Microsoft windows is a software program that makes your ibm pc — Ваш верный помощник с OS Windows

Microsoft
Windows (or simply Windows) is a software programme that makes your
IBM PC (or compatible) easy to use. It does this by simplifying the
computer’s user
interface. The
word interface
refers
to the way you give your computer commands, the way you interact with
it.

Usually
the interface between you and the computer consists of the screen and
the keyboard, you interact with the computer by responding to what’s
on the screen, typing in commands at the DOS command line to do your
work.

DOS
often isn’t very intelligent at interpreting your commands and most
people consider it awkward or intimidating as a user interface. These
commands can be confusing and difficult to remember. Who wants to
learn lots of computer commands just to see what’s on your disk, copy
a file, or format a disk?

Windows
changes much of this. What’s been missing from the PC is a programme
that makes the computer easy to use. Windows is just such a program.
With Windows, you can run programmes, enter and move data around, and
perform DOS-related tasks simply by using the mouse
to
point at objects on the screen. Of course, you also use the keyboard
to type in letters and numbers. Windows interprets your actions and
tells DOS and your computer what to do.

In
addition to making DOS housekeeping tasks such as creating
directories, copying files, deleting files, formatting disks, and so
forth, easier, Windows makes running your favorite applications
easier,
too. (An application is a software package that you use for a
specific task, such as word processing). Windows owes its name to the
fact that it runs each programme or document in its own separate
window.
(A
window is a box or frame on the screen.) You can have numerous
windows on the screen at a time, each containing its own programme
and/or document. You can then easily switch between programs without
having to close one down and open the next.

Another
feature is that Windows has a facility — called the Clipboard — that
lets you copy material between dissimilar document types, making it
easy to cut
and
paste
information
from, say, a spreadsheet into a company report or put a scanned
photograph of a house into a real estate brochure. In essence,
Windows provides the means for seamlessly joining the capabilities of
very different application programs. Not only can you paste portions
of one document into another, but by utilizing more advanced
document-linking features those pasted elements remain «live».
That is, if the source document (such as some spreadsheet data)
changes, the results will also be reflected in the secondary document
containing the pasted data.

As
more and more application programmes are written to run with Windows,
it’ll be easier for anyone to learn how to use new programmes. This
is because all application programmes that run in Windows use similar
commands and procedures. Windows comes supplied with a few of its own
handy programmes. There’s a word-processing programme called Write, a
drawing programme called Paintbrush, a communications programme
called Terminal for connecting to outside information services over
phone lines, small utility programmes that are helpful for keeping
track of appointments and notes, a couple of games to help you escape
from your work, and a few others.

Years
of research went into developing the prototype of today’s popular
graphical user interfaces. It was shown in the early 1980s that the
graphical user interface, in conjunction with a hand-held pointing
device (now called the mouse), was much easier to operate and
understand than the older-style keyboard-command approach to
controlling a computer. A little-known fact is that this research was
conducted by the Xerox Corporation and first resulted in the Xerox
Star computer before IBM PCs or Macintoshes existed. It wasn’t until
later that the technology was adapted by Apple Computer for its
Macintosh prototype, the Lisa.

Microsoft WINDOWS (or simply WINDOWS) is a software program that makes your IBM PC (or compatible) easy to use. It dose this by simplifying the computer’s interface — a terms that refers to the way you give your computer comments, the way you interact with it.

Basically, the computer component of our computer system is a series of electronic circuits. Therefore , in order to communicate with it, we need an input device such as a keyboard or mouse, and an output device such as printer or monitor.

Microsoft Windows , (или просто Windows) это программа , которая делает ваш IBM PC (или совместимый) прост в использовании. Она делает это за счет упрощения пользовательского интерфейса компьютера.

Интерфейс слово относится к тому , как вы даете команд на компьютере, то , как вы взаимодействуете с ним.

Обычно интерфейс между вами и компьютером состоит из экрана и клавиатуры: вы взаимодействовать с компьютером, отвечая на то , что на экране, набрав команд в командной строке DOS , чтобы делать свою работу.

DOS часто не очень умный при интерпретации ваших команд и большинство людей считают неудобным или пугающим в качестве пользовательского интерфейса. Эти команды могут сбивать с толку и трудно вспомнить. Кто хочет узнать много компьютерных команд, чтобы посмотреть , что находится на вашем диске, скопировать файл, или отформатировать диск?

Окна изменяет большую часть этого. Что пропал с ПК это программа , которая позволяет легко использовать компьютер. Окна это просто такая программа. В операционной системе Windows можно запускать программы, вводить и перемещать данные, а также выполнять DOS-задачи , связанные с простым с помощью мыши , чтобы указать на объекты на экране. Конечно, вы можете также использовать клавиатуру для ввода букв и цифр.

Windows , интерпретирует ваши действия и говорит DOS и ваш компьютер , что делать.

В дополнение к созданию задач DOS ведению домашнего хозяйства , такие как создание каталогов, копирование файлов, удаление файлов, форматирование дисков и т.д., проще, Windows делает запуск ваших любимых приложений проще, тоже. (Приложение представляет собой программный пакет , который вы используете для конкретной задачи, такие как обработка текстов. WordPerfect является примером приложения. В этой книге я буду использовать программу слов и применение взаимозаменяемы.)

Windows , обязана своим названием к Тот факт , что он работает каждую программу или документ в его собственном отдельном окне. (Окно представляет собой окно или кадр на экране.) Вы можете иметь многочисленные окна на экране в то время, каждая из которых содержит свою собственную программу и / или документ. Вы можете легко переключаться между программами без необходимости закрывать один вниз и откройте следующий.

Еще одной особенностью является то , что Windows , есть средство — называется буфером обмена — что позволяет копировать материал между разнородными типами документов, что делает его легко вырезать и вставлять информацию из, скажем, электронную таблицу в отчет компании или поместить отсканированную фотографию дома в брошюра о недвижимости. В сущности, Windows предоставляет средства для присоединения бесшовно возможности самых различных прикладных программ. Мало того, вы можете вставить части одного документа в другой, но за счет использования более продвинутых документов сшивание особенности эти вставленные элементы остаются «вживую». То есть, если исходный документ (например, некоторые электронные таблицы данных) изменения, результаты также будут отражены в документе , содержащем вторичного вставленных данных.

Поскольку все больше и больше прикладных программ написаны для работы с Windows, это будет проще для тех , кто , как использовать новые программы. Это потому , что все прикладные программы, работающие в Windows , используют аналогичные команды и процедуры.

Окна поставляется с несколькими из своих собственных удобных программ, и мы обсудим их в этой книге. Там в программе обработки текстов под названием Write, программа для рисования под названием Paintbrush, программа связи вызываемый терминал для подключения к внешним информационным услугам по телефонным линиям, маленьких вспомогательных программ, которые полезны для отслеживания назначений и заметок, несколько игр , чтобы помочь вы убегаете от вашей работы, и некоторые другие.

Годы исследований вошли в развитие прототип современных популярных графических пользовательских интерфейсов. Как было показано в начале 1980 — х , что графический пользовательский интерфейс, в сочетании с ручной указывая устройство (теперь называется мышь), было гораздо легче работать и понимать , чем клавиатура командно-подход старого стиля к управлению компьютером. Малоизвестный факт, что это исследование было проведено с помощью Xerox Corporation и впервые привела к компьютеру Xerox Star , прежде чем персональных компьютеров IBM или Macintoshes существовали. Он не был до позже , что эта технология не была адаптирована Apple Computer для своего прототипа Macintosh, на Лизу.

What
is MS-DOS

The
Microsoft MS-DOS operating
system is
like a translator between you and your computer. The programs in this
operating system allow you communicate with your computer, your disk
drives and your printer, letting you use these resources to your
advantage.

MS-DOS
also helps you to manage programs and data. Once you have loaded
MS-DOS into your computer’s memory, you can compose letters and
reports, run programs and languages such as Microsoft GW-BASIC, and
use devices such as printers and disk drives.

Terms You Should Know

When you are introduced to a
new or different idea, you must often a new set of words to
understand the idea. The MS-DOS operating system is no exception. The
following pages explain some terms you will know so that you can read
and use the manuals.

Program

Programs,
often called application
programs, applications, or
softwareare
series of instructions written in computer languages. These
instructions are stored in files and tell your computer to perform a
task. For example, a program might tell your computer to
alphabetically sort a list of names. Spreadsheets and word processors
are other examples of programs.

File

A
file is a collection of related information, like the contents of a
file folder in a desk drawer. File folders, for instance, might
contain business letters, office memos, or monthly sales data. Files
on your disks could also contain letters, memos, or data. For
example, your MS-DOS master disk contains more than thirty files.
Your other disks may contain files that you’ve created, or that came
with the disk.

Filename

Just
as each folder in a file cabinet has a label, each file on a disk has
a name. This name has two parts: a filename
and
an extension.
A
filename can be from one to eight characters in length, and can be
typed in uppercase or lowercase letters. MS-DOS automatically
converts filenames to uppercase letters.

Filename
extensions consist of a period followed by one, two, or three
characters. Extensions are optional, but it’s good idea to use them,
since they are useful for describing the contents of a file to you
and to MS-DOS For instance, if you want to be able to quickly
identify your report files, you can add the filename extension .rpt
to
each one. Here’s an example of a filename with this extension:

progress .rpt

filename filename
extension

Directory

A directory is a table of
contents for a disk. It contains the names of your files, their
sizes, and the dates they were last modified.

Volume
Label

When
you use a new disk, you can put a label on the outside of it to help
you identify its contents. You can also give each of your disks an
internal name, called a volume
label.

You
can look at the volume label on a disk by displaying its directory,
programs may look at the volume label to see if you are using the
correct disk. So make sure that you label your disks.

Disk Drive

To
use the files or programs that are on a floppy disk, you must first
insert the disk into a floppy disk drive Floppy disk drives are
commonly referred to as the A drive and the B drive. A hard disk
drive, normally installed inside your computer, is usually referred
to as the C drive.

Drive
Name

A
complete drive
name consists
of a drive
letter and
a colon.
When
using a command, you may need to type a drive name before your
filename to tell MS-DOS where to find the disk that contains your
file. For example, suppose you have a file named finances.doc
on
the disk in drive B To tell MS-DOS where to find this file you would
type the drive name before the filename:

b: finances.doc

drive name filename with
extension

Command

Just
as you will run programs to create and update files containing your
data, you will also need to run some special programs, called MS-DOS
commands, that let you work with entire files.

When
you type MS-DOS commands, you are asking the computer to perform
tasks. For example, when you use the diskcopy command to copy your
MS-DOS master disk, you are using a file named diskcopy.exe,
whose
task is to copy the files on the MS-DOS disk.

Error messages

If
you or your computer makes a mistake when using a device or
MS-command, MS-DOS displays an appropriate error
message. Error
messages apply to general errors (such as misspelling a command) or
to device errors (such as trying to use a printer that is out of
paper) For a complete list and explanation of each MS-DOS error
message (device and general), see the MS-DOS
User ‘s Reference, Appendix
F.

Memory

Memory
is
the place in your computer where information is actively used. When
you run a program, MS-DOS stores that program and the files
it
uses in the computer’s available memory. Some programs and files use
more memory than others, depending on how large and complex they are.

Devices

Whenever
you use your computer, you supply the information (input) and expect
a result (output). Your computer uses pieces of hardware called
devices
to
receive input and send output.

For example, when you type a
command, your computer receives input from your keyboard and disk
drive, and usually sends output to your screen. It can also receive
input from a mouse, or send output to a printer. Some devices, such
as disk drives, perform both input and output.

Device
Names

Device
names are
special names given to each device that your computer «knows»
about. An example of a device name is LPT1, which stands for the
first parallel lineprinter connected to your computer.

When
you add a new device, such as a mouse, to your computer, you
sometimes need to tell MS-DOS about it by setting up (configuring)
your computer for that device.

как их не надо часто поливать. Иногда
для работы мне нужно много книг, журналов,
справочников. Компьютер часто завален
книгами. Мне не хватает места. Мне
приходится ставить компьютер и все
устройства на пол. Но это не страшно,
так как на полу лежит толстый мягкий
ковер. Я слежу за тем, чтобы шнур не
попадал ни под какие предметы. Я знаю,
что, если произойдут какие-то сбои в
работе техники, лучше обратиться за
помощью к профессионалу. Но пока все в
порядке. И я получаю удовольствие от
работы. Особенно, когда работаешь, и

What
is a network?

A network is simply
two or more computers linked together. It allows users to share not
only data files and software applications, but also hardware like
printers and other computer resources such as fax.

Most networks link
computers within a limited area – within a department, an office,
or a building. These are called Local Area Networks, or LANs. A LAN
connects network devices over a relatively short distance. A
networked office building, school, or home usually contains a single
LAN, though sometimes one building will contain a few small LANs, and
occasionally a LAN will span a group of nearby buildings. In IP
networking, one can conceive of a LAN as a single IP subnet (though
this is not necessarily true in practice).

Besides operating in a
limited space, LANs include several other distinctive features. LANs
are typically owned, controlled, and managed by a single person or
organization. They also use certain specific connectivity
technologies, primarily Ethernet
and Token Ring.

But networks can link
computers across the world, so you can share information with someone
on the other side of the world as easily as sharing with a person at
the next desk. When networks are linked together in this way, they
are called Wide AREA Networks, or WANs.

A
wide-area network spans a large physical distance. A WAN like the
Internet spans most of the world!

A
WAN is a geographically-dispered collection of LANs. A network device
called a router
connects LANs to a WAN. In IP networking, the router maintains both a
LAN address
and a WAN address.

WANs
differ from LANs in several important ways. Like the Internet, most
WANs are not owned by any one organization but rather exist under
collective or distributed ownership and management.

Networks
increase productivity by allowing workers to share information easily
without printing, copying, telephoning, or posting. They also have
money by sharing peripherals such as printers.

users need to access or share with others.
___________ This is the
desktop computer or notebook computer on your desk. It is linked to
the server, and can access files and applications on it. Each
computer on the network has a device called a network interface card
which connects the computer to the network. Many computers come with
these cards fitted as standard.
___________ Once you have a
network you can share any number of these including printers,
scanners, CD-ROM drives, and backup devices.
___________ Desktops

in a network can be connected in different ways, in different
topologies. Topology is a geometric arrangement of the network. The
three basic ways of connecting computers are: a bus, a ring, and a
star topology.

A
bus topology has all the computers connected to a common cable. The
data travels in both directions along the cable. If a computer fails,
or we remove one from the network, it won’t affect the other
computers. But if the main cable (a backbone) fails, the entire
network fails too.

In
a ring topology each computer is connected to its neighbor in a
circle. The data flows in one direction (clockwise or
counterclockwise) round the ring. If a cable breaks or one of the
computers fails, the whole network will be affected.

A
star topology has a server computer and a separate cable connecting
the server to each of the other computers in the network. This server
is also called a hub. The central server controls the flow of data in
the network. If any computer fails, it won’t affect the network.
But if the central server fails, the whole network will fail.

A
mesh topology includes the concept of routes. A message in the
network can take any possible path from source to destination. It is
the most reliable network topology, because if any computer or a
cable fails, it won’t affect the entire network. But at the same
time it’s the most expensive one.

Most
networks are usually a combination of star, ring and bus topologies
to overcome some of these problems.

Task
7. Which topologies do these statements refer to?

If one of the computers
fails, the whole network will be affected.
If we remove a computer from
the network, it won’t affect the other computers.
If the main cable fails, the
whole network will fail.
If the central server fails,
the whole network will fail.
If a cable breaks, the whole
network will be affected.
If
a computer fails, it won’t affect the other computers.

Unit 1. History of computers

Text. History of computers

Let us take a look at the history of computers that we know today. The very first calculating device used was the ten fingers of a man’s hands. This, in fact, is why today we still count in tens and multiples of tens. Then the abacus was invented, a bead frame in which beads are moved from left to right. People went on using abacus till the 16^th century and they sometimes use it now because it can be understood without knowing how to read.

During the 17^th and 18^th centuries many people tried to find easy ways of calculating. J. Napier, a Scotsman, devised a mechanical way of multiplying and dividing, which is how the modern slide rule works. Henry Briggs used Napier’s ideas to produce logarithm tables which all mathematicians use today. Calculus, another branch of mathematics, was independently invented by both Sir Isaac Newton, an Englishman, and Leibniz, a German mathematician.

The first real calculating machine appeared in 1820 as the result of several people’s experiments. This type of machine, which saves a great deal of time and reduces the possibility of making mistakes, depends on a series of ten-toothed gear wheels. In 1830 Charles Babbage, an Englishman, designed a machine that was called “The Analytical Engine”. This machine, which Babbage showed at the Paris Exhibition in 1855, was an attempt to cut out the human being altogether, except for providing the machine with the necessary facts about the problem to be solved. He never finished his work, but many of his ideas were the basis for building today’s computers.

In 1930, the first analog computer was built by an American named Vannevar Bush. This device was used in World War II to help aim guns. Mark I, the name given to the first digital computer, was completed in 1944. The men responsible for this invention were Professor Howard Aiken and some people from IBM. This was the first machine that could figure out long lists of mathematical problems, all at a very fast rate. In 1946 two engineers at the University of Pennsylvania, J. Eckert and J. Mauchly, built the first digital computer using parts called vacuum tubes. They named their invention ENIAC. Another important advancement in computers came in 1947, when John von Newman developed the idea of keeping instructions for the computer inside the computer’s memory.

The first generation computers, which used vacuum tubes, came out in 1950. Univac I is an example of these computers which could perform thousands of calculations per second. In 1960 the second generation of computers was developed and these could perform work ten times faster then their predecessors. The reason of this extra speed was the use of transistors instead of vacuum tubes. The second generation computers were smaller, faster and more dependable than first generation computers. The third generation computers appeared on the market in 1965. These computers could do a million calculations a second, which is 1000 times as many as the first generation computers. Unlike the second generation computers, these are controlled by tiny integrated circuits and are consequently smaller and more dependable.

In the fourth generation computers integrated circuits have been greatly reduced in size. This is due to microminiaturization, which means that the circuits are much smaller than before; as many as 1000 tiny circuits now fit onto a single chip. A chip is a square or rectangular piece of silicon, usually from 1/10 to ¼ inch, upon which several layers of an integrated circuit are etched or imprinted, after which the circuit is encapsulated in plastic, ceramic or metal. The fourth generation computers are 50 times faster than third generation computers and can complete approximately 1,000,000 instructions per second.

At the rate computer technology is growing, today’s computers might be obsolete tomorrow. It has been said that if transport technology had developed as rapidly as computer technology, a trip across the Atlantic Ocean today would take a few seconds.

Unit 2. Computers in our life.

Text. Computers changed the world.

Computers changed the world a lot. It helped a man to step forward into the future. Thanks to computers, space exploration came true, new designs of vehicles and other transportation were made; entertainment became more entertaining, medical science made more cures for diseases, etc. The computers influenced our lives in many ways. They did make life a lot easier. Without computers the world would be a harder place to live in.

Computers are being used more and more extensively in the world today for the simple reason that they are far more efficient than human beings. They have much better memories, can store great amount of information, solve a series of problems and make thousands logical decisions without becoming tired or bored. They can find solutions to problems in a fraction of the time it takes a human being to do the job. A computer can replace people in dull, routine work.

In fact, computers can do many things we do but faster and better. They can control machines at factories, make the weather forecast and even play chess, write poetry or compose music. Computers make all modern communications possible. They operate telephony, radio and television broadcasts. Local and wide area networks link companies and their departments, universities and just simple users all over the world.

It is difficult to say in what area of our life computers are not used. First of all it is science. Computers are used by scientists and researchers to perform difficult calculations and to build simulations and exact models.

Business uses computers to keep track of accounts, money, or items that they need. You may notice business people using computers a lot, especially the laptop computers, portable computers that can be taken to any place. You may see people use things like pie-charts and graphs when they present information to other business people at meetings. Most of those charts were made by computers. The business field uses the computers a lot for their companies and organizations.

Another area computers impacted on is the entertainment area. Most of the people like science fiction or action movies, especially the ones with special effects made by computers. Most of the movies today use computer graphics to make things more realistic. Some of the cartoons are completely made by computers. We can’t help mentioning computer games. The constantly improving graphics and sound make them very popular.

Computers are also widely used in education. They help students in preparing projects and essays. They can type their reports in a word-processing program, search information in the Internet. There are also special educational programs on different subjects, so you can use a computer as a tutor, what is particularly important for disabled people. Teachers use computers as well. They use computers to keep track of grades, type out instruction for their students, etc.

Computer helped the medical area a lot. The pharmacists use computers to keep a record of what medication to give to a patient and the amount they need. Most computers in hospitals are used to keep data of patients and their status. Scientists need the help of computers to find cures for diseases.

In a very short period of time computers changed our life. They changed the way in which many kinds of work are performed. Computers can remove many of the routine and boring tasks from our lives, thereby leaving us with more time for interesting, creative work. The development in many fields would be impossible without computers. No doubt, our life became different with this great invention of the 20^th century.

Unit 3.What is a computer?

Text. What is a computer?

Computer is a machine designed to store and process electronically, specially prepared pieces of information which are called data. Computers are made up of millions of electronic devices capable of storing data or moving it at enormous speed through complex circuits with different functions.

When talking about computers, both hardware and software need to be considered. Hardware refers to the machinery, whereas software refers to the programs which control and coordinate the activities of hardware while processing the data.

Software is the term used to describe the instructions that tell the hardware how to do a task. Without software instructions, the hardware doesn’t know what to do. People, however, are the most important component of the computer system: they create the computer software instructions and respond to the procedures that those instructions present.

The basic job of a computer is the processing of information. The machine accepts information in the form of instructions called a program and characters called data, performs mathematical and/or logical operations and then supplies the results of these operations.

The program, which tells the computer what to do and the data, which provide the information needed to solve the problem, are kept inside the computer in a place called memory.

The information presented to the machine is the input, the internal manipulative operations – the processing, and the result – the output.

A computer has no known limit on the kinds of things it can do; its versatility is limited only by the imagination of the people using it.

During the early period of computer development, these machines were large, not so reliable and very expensive to own. A large number of support personnel were needed to keep the equipment operating. This has changed now that computers have become portable, more compact and cheaper.

Vocabulary

to store information – хранить информацию

Unit 4. Hardware and software.

Text 1. Software

A computer system implies a mixture of integrated parts working together. It consists of two parts. The first part is hardware – the physical, electronic devices that are thought of as “computers”. The hardware consists of equipment: keyboard, mouse, monitor, system unit and other devices. The second part is software – the programs that control and coordinate the activities of the computer hardware and that direct the processing of data.

There are two major kinds of software: system software and application software. The user interacts with application software. System software enables the application software to interact with the computer hardware. System software is “background” software that helps the computer manage its own internal resources. The most important system software program is the operating system, which interacts between the application software and the computer. The operating system handles such details as running (“executing”) programs, storing data and programs, and processing data.

Application software might be described as “end-user” software. Application software performs useful work on general-purpose tasks such as word processing and cost estimating. Application software may be packaged or custom-made.

Packaged software is programs prewritten by professional programmers that are typically offered for sale.

Custom-made software, or custom programs, is programs written for a specific purpose and for a specific organization. Using computer languages, programmers create this software to instruct the company computer to perform whatever tasks the organization wants. A program might compute payroll checks, keep track of goods in the warehouse, calculate sales commissions, or perform similar business functions.

General-purpose programs, or “basic applications”, are widely used in nearly all career areas. One of these basic applications is a browser to navigate, explore, and find information in the Internet.

There are more advanced applications that are more specialized than the basic applications. They are widely used within certain career areas. One of the most exciting advanced applications is multimedia, which integrates video, music, voice, and graphics to create interactive presentations.

Text 2. Hardware.

Microcomputer hardware – the physical equipment – falls into five categories. They are input devices, the system unit, secondary storage, output devices and communications devices.

Input devices translate data and programs that humans can understand into a form that the computer can process. The most common input devices for microcomputers are the keyboard and the mouse. The keyboard on a computer looks like a typewriter keyboard, but it has additional specialized keys. A mouse is a pointing device that typically rolls on the desktop. It directs the insertion point, or cursor, on the display screen. As you glide the mouse, the arrow on the screen moves in the direction of your movement. A mouse has one or more buttons. You click (press and release the button one time) or double-click the mouse button to open the document or to start the program, for example.

The large metal box, or the case, with its contents (electronic circuitry) is called the system unit. The two most important components of the system unit are:

1. The central processing unit (CPU) controls and manipulates data to produce information. A microcomputer’s CPU is contained on a single integrated circuit or microprocessor chip. These chips are called microprocessors.

2. Memory, also known as primary storage or random access memory (RAM), holds data and program instructions for processing the data. It also holds the processed information before it is output. Memory is sometimes referred to as temporary storage, because it will be lost if the electrical power to the computer is disrupted or cut off. Data and instructions are held in memory only as long as the electrical power to the computer is on. Memory is located in the system unit on the tiny memory chips.

Secondary storage also holds data and programs. It stores permanently, that is, the data and programs remain even after the turning off the electrical power. The most important kinds of secondary storage devices are: floppy disks, hard disks, optical disks, flash cards.

Floppy disks, or diskettes, were widely used to store and transport data from one computer to another. They are called “floppy” because data is stored on a very thin flexible plastic disk. The disk rotates within a protective sturdy plastic cover. Today’s standard floppy disk is a ”3,5-inch 2HD” (two-sided high density) with a capacity to hold the equivalent of 400 type-written pages.

Hard disks are typically used to store programs and very large data files. Hard disks have much greater capacity and are able to access information much faster than floppy disks. Almost every microcomputer system has an internal hard disk that is permanently installed within the system cabinet. This disk is used to store system programs, application programs and data.

Optical disks are laser technology and have great capacity. There are two basic types of optical disks: CD and DVD. CDs (compact disks) are widely used today, they are used to store great amount of data. DVD stands for both digital versatile disk and digital video disk. Its capacity is far greater than CD’s. DVDs can be used for all the things that CDs are used for, but also they can distribute full-length motion pictures.

Flash cards have become very popular today, because they are very compact and therefore more convenient. Flash cards can hold great number of gigabytes of data.

Output devices are pieces of equipment that translate the processed information from the CPU into a form that humans can understand. One of the most important output devices is the monitor or video display screen, which resembles a television screen. The monitor displays text characters and video images. It allows you to see the result of your work going on inside the system unit. The image that you see is made up of tiny dots called pixels. The sharpness of the picture depends on the number and size of these pixels. The more pixels, the sharper the image. This is called resolution. Another important output device is a printer, a device that produces printed paper output.

Communications hardware sends and receives data and programs from one computer or secondary storage device to another. Many microcomputers use a modem. This device converts the electronic signals that can travel over a telephone line. A modem at the other end of the line then translates the signals for the receiving computer. A modem may be internal or located inside a microcomputer’s system cabinet. It may also be a separate unit, or external.

Unit 5. Programs and programming languages.

Text. Programs and programming languages

Computers can deal with different kinds of problems if they are given the right instructions for what to do. Instructions are first written in one of the high-level languages, e.g. FORTRAN, COBOL, ALGOL, PL/I, PASCAL, BASIC, or C, depending on the type of problem to be solved. A program written in one of these languages is often called a source program, and it cannot be directly processed by the computer until it has been compiled, which means interpreted into machine code. Usually a single instruction written in a high-level language, when transformed into machine code results in several instructions. Here is a brief description of some of the many high-level languages:

FORTRAN acronym for FORmula TRANslation. This language is used for solving scientific and mathematical problems. It consists of algebraic formulae and English phrases. It was first introduced in the United States in 1954.

COBOL acronym for COmmon Business-Oriented Language. This language is used for commercial purposes. COBOL, which is written using English statements, deals with problems that do not involve a lot of mathematical calculations. It was first introduced in 1959.

ALGOL acronym for ALGOrithmic Language. Originally called IAL, which means International Algebraic Language. It is used for mathematical and scientific purposes. ALGOL was first introduced in Europe in I960.

PL/I Programming Language I. Developed in 1964 to combine features of COBOL and ALGOL. Consequently, it is used for data processing as well as scientific applications.

BASIC acronym for Beginner’s All-purpose Symbolic Instruction Code. Developed in 1965 at Dartmouth College in the United States for use by students who require a simple language to begin programming.

C developed in the 1970s to support the UNIX operating system. C is a highly portable general-purpose language.

Other such languages are APL (developed in 1962), PASCAL (named after Blaise Pascal and developed in 1971), and LISP and PROLOG, both of which are used for work in artificial intelligence. LOGO is a development of LISP which has been used to develop computer-based training (CBT) packages.

When a program written in one of these high-level languages is designed to do a specific type of work such as calculate a company’s payroll or calculate the stress factor on a roof, it is called an applications program. Institutions either purchase these programs as packages or commission their own programmers to write them to meet the specifications of the users.

The program produced after the source program has been converted into machine code is referred to as an object program or object module. This is done by a computer program called the compiler, which is unique for each computer. Consequently, a computer needs its own compiler for the various high-level languages if it is expected to accept programs written in those languages. For example, in order that an IBM RS/6000 may process a program in FORTRAN, it needs to have a compiler that would understand that particular model and the FORTRAN language as well.

The compiler is a systems program which may be written in any language, but the computer’s operating system is a true systems program which controls the central processing unit (CPU), the input, the output, and the secondary memory devices. Another systems program is the linkage editor, which fetches required systems routines and links them to the object module (the source program in machine code). The resulting program is then called the load module, which is the program directly executable by the computer. Although systems programs are part of the software, they are usually provided by the manufacturer of the machine.

Unlike systems programs, software packages are sold by various vendors and not necessarily by the computer manufacturer. They are a set of programs designed to perform certain applications which conform to the particular specifications of the user. Payroll is an example of such a package which allows the user to input data — hours worked, pay rates, special deductions, names of employees — and get salary calculations as output. These packages are coded in machine language (0s and 1s) on magnetic tapes or disks which can be purchased, leased, or rented by users who choose the package that most closely corresponds to their needs.

Unit 6. Operating systems MS-DOS and Windows.

Text 1. MS-DOS and its main terms.

What is MS-DOS.

The Microsoft MS-DOS operating system is like a translator between you and your computer. The programs in this operating system allow you communicate with your computer, your disk drives and your printer, letting you use these resources to your advantage.

MS-DOS also helps you to manage programs and data. Once you have loaded MS-DOS into your computer’s memory, you can compose letters and reports, run programs and languages such as Microsoft GW-BASIC, and use devices such as printers and disk drives.

Terms you should know.

When you are introduced to a new or different idea, you must often learn a new set of words to understand the idea. The MS-DOS operating system is not an exception. The following pages explain some terms you will need to know so that you can read and use the manuals.

Program.

Programs, often called application programs, or applications, or software are series of instructions written in computer languages. These instructions are stored in files and tell your computer to perform a task. For example, a program might tell your computer to alphabetically sort a list of names. Spreadsheets and word processors are other examples of programs.

File.

A file is a collection of related information, like the contents of a file folder in a desk drawer. File folders, for instance, might contain business letters, office memos, or monthly sales data. Files on your disks could also contain letters, memos, or data. For example, your MS-DOS master disk contains more than thirty files. Your other disks may contain files that you’ve created, or that came with the disk.

Filename.

Just as each folder in a file cabinet has a label, each file on a disk has a name. This name has two parts: a filename and an extension. A filename can be from one to eight characters in length, and can be typed in uppercase or lowercase letters. MS-DOS automatically converts filenames to uppercase letters.

Filename extensions consist of a period followed by one, two or three characters. Extensions are optional, but it’s a good idea to use them, since they are useful for describing the contents of a file to you and to MS-DOS. For instance, if you want to be able to quickly identify your report files, you can add the filename extension .rpt to each one. Here’s an example of a filename with this extension:

progress. rpt

Directory.

A directory is a table of contents for a disk. It contains the names of your files, their sizes, and the dates they were last modified.

Volume label.

When you use a new disk, you can put a label on the outside of it to help you identify its contents. You can also give your disks an internal name, called a volume label.

You can look at the volume label on a disk by displaying its directory. Some programs may look at the volume label to see if you are using the correct disk. So make sure that you label your disks.

Disk drive.

To use the files or programs that are on a floppy disk, you must first insert the disk into a floppy disk drive. Floppy disk drives are commonly referred to as the A drive and the B drive. A hard disk drive, normally installed inside your computer, is usually referred to as the C drive.

Drive name.

A complete drive name consists of a drive letter and a colon. When using a command, you may need to type a drive name before your filename to tell MS-DOS where to find the disk that contains your file. For example, suppose you have a file named finances.doc on the disk in drive B. To tell MS-DOS where to find this file you would type the drive name before the filename:

b: finances.doc

Command.

Just as you will run programs to create and update files containing your data, you will need to run some special programs, called MS-DOS commands, which let you work with entire files.

When you type MS-DOS commands, you are asking the computer to perform tasks. For example, when you use the diskcopy command to copy your MS-DOS master disk, you are using a file named diskcopy.exe, whose task is to copy the files on the MS-DOS disk.

Error messages.

If you or your computer makes a mistake when using a device or MS-DOS command, MS-DOS displays an appropriate error message. Error messages apply to general errors (such as misspelling a command) or to device errors (such as trying to use a printer that is out of paper).

Memory.

Memory is a place in your computer where information is actively used. When you run a program, MS-DOS stores that program and the files it uses in the computer’s available memory. Some programs and files use more memory than others, depending on how large and complex they are.

Devices.

Whenever you use your computer, you supply the information (input) and expect a result (output). Your computer uses pieces of hardware called devices to receive input and send output.

For example, when you type a command, your computer receives input from your keyboard and disk drive, and usually sends output to your screen. It can also receive input from a mouse, or send output to a printer. Some devices, such as disk drives, perform both input and output.

Device names.

Device names are special names given to each device that your computer “knows” about. An example of a device name is LPT 1, which stands for the first parallel line printer connected to your computer.

When you add a new device, such as a mouse, to your computer, you sometimes need to tell MS-DOS about it by setting up (configuring) your computer for that device.

Text 2. Windows.

Microsoft Windows (or simply Windows) is a software program that makes your PC easy to use. It does this by simplifying the computer’s user interface.

The word interface refers to the way you give your computer commands, the way you interact with it.

Usually the interface between you and the computer consists of the screen and the keyboard: you interact with the computer by responding to what’s on the screen, typing in commands at the DOS command line to do your work.

DOS often isn’t very intelligent at interpreting your commands and most people consider it awkward or intimidating as a user interface. These commands can be confusing and difficult to remember. Who wants to learn lots of computer commands just to see what’s on your disk, copy a file, or format a disk?

Windows changes much of this. What’s been missing from the PC is a program that makes your computer easy to use. Windows is just such a program. With Windows you can run programs, enter and move data around and perform DOS-related tasks simply by using a mouse to point at objects on the screen. Of course, you also use a keyboard to type in letters and numbers.

Windows interprets your actions and tells DOS and your computer what to do.

In addition to making DOS housekeeping tasks, such as creating directories, copying files, deleting files, formatting disks, and so forth, easier, Windows makes running your favorite applications easier too. (An application is a software package that you use for a specific task, such as word processing.)

Windows owes its name to the fact that it runs each program or a document in its own separate window. (A window is a box or a frame on the screen.). You can have numerous windows on the screen at a time, each containing its own program and/or document. You can then easily switch between programs without having to close one down and open the next.

Another feature is that Windows has a facility called the Clipboard that lets you copy material between dissimilar document types, making it easy to cut and paste information from, say, a spreadsheet into a company report or put a scanned photograph of a house into a real estate brochure. In essence, Windows provides the means for seamlessly joining the capabilities of very different application programs. Not only can you paste portions of one document into another, but by utilizing more advanced document-linking features those pasted elements remain “live”. That is, if the source document (such as some spreadsheet data) changes, the result will also be reflected in the secondary document containing the pasted data.

As more and more application programs are written to run with Windows, it’ll be easier for anyone to learn how to use new programs. This is because all application programs that run in Windows use similar commands and procedures.

Windows comes supplied with a few of its own handy programs. There’s a word-processing program called Word, a drawing program called Paint, a communications program called Terminal for connecting to outside information services over phone lines, small utility programs that are helpful for keeping track of appointments and notes, a couple of games to help you escape from your work, and a few others.

Years of research went into developing the prototype of today’s popular user interfaces. It was shown in the early 1980s that the graphical user interface, in conjunction with a hand-held pointing device (now called the mouse), was much easier to operate and understand than the older-style keyboard-command approach to controlling a computer. A little-known fact is that this research was conducted by the Xerox Corporation and first resulted in the Xerox Star computer before IBM PCs or Macintoshes existed. It wasn’t until later that the technology was adapted by Apple Computer for its Macintosh prototype, the Lisa.

Unit 7. Computer networks.

Text. Computer networks.

Computer networks link computers by communication lines and software protocols, allowing data to be exchanged rapidly and reliably. Traditionally, networks have been split between wide area networks (WANs) and local area networks (LANs). A WAN is a network connected over long distance telephone lines, and a LAN is a localized network usually in one building or a group of buildings close together. The distinction, however, is becoming blurred. It is now possible to connect up LANs remotely over telephone links so that they look as though they are a single LAN. Originally, networks were used to provide terminal access to another computer and to transfer files between computers. Today, networks carry e-mail, provide access to public databases and bulletin boards, and are beginning to be used for distributed systems. Networks also allow users in one locality to share expensive resources, such as printers and disk-systems. Distributed computer systems are built using networked computers that co-operate to perform tasks. In this environment each part of the networked system does what it is best at. The high-quality bit-mapped graphics screen of a personal computer or workstation provides a good user interface. The mainframe, on the other hand, can handle large numbers of queries and return the results to the users. In a distributed environment, a user might use his PC to make a query against a central database. The PC passes the query, written in a special language (e.g. Structured Query Language — SQL), to the mainframe, which then parses the query, returning to the user only the data requested. The user might then use his PC to draw graphs based on the data. By passing back to the user’s PC only the specific information requested, network traffic is reduced. If the whole file were transmitted, the PC would then have to perform the query itself, reducing the efficiency of both network and PC.

In the 1980s, at least 100,000 LANs were set up in laboratories and offices around the world. During the early part of this decade, synchronous orbit satellites lowered the price of long-distance telephone calls, enabling computer data and television signals to be distributed more cheaply around the world. Since then, fibre-optic cable has been installed on a large scale, enabling vast amounts of data to be transmitted at a very high speed using light signals.

The impact of fibre optics will considerably reduce the price of network access. Global communication and computer networks will become more and more a part of professional and personal lives as the price of microcomputers and network access drops. At the same time, distributed computer networks should improve our work environments and technical abilities.

Unit 8. The Internet.

Text 1. The Internet.

The Internet, a global computer network which embraces millions of users all over the world, began in the United States in 1969 as a military experiment. It was designed to survive a nuclear war. Information sent over the Internet takes the shortest path available from one computer to another. Because of this, any two computers on the Internet will be able to stay in touch with each other as long as there is a single route between them. This technology, known as packet switching, in which data meant for another location is broken up into little pieces, each with its own “forwarding address” had the promise of letting several users share just one communications line. Owing to this technology, if some computers on the network are knocked out (by a nuclear explosion, for example), information will just route around them. One such packet switching network already survived a war. It was the Iraq computer network which was not knocked out during the Gulf War.

Most of the Internet host computers (more than 50%) are in the United States, while the rest are located in more than 100 other countries. Although the number of host computers can be counted fairly accurately, nobody knows exactly how many people use the Internet, there are millions, and their number is growing by thousands each month worldwide.

The most popular Internet service is e-mail. The people, who have access to the Internet, use the network for sending and receiving e-mail messages. Every person connected can communicate with anyone on the Internet, or to use any public resources available in it, to publish any documents and ideas, to sell or to buy products and online goods and services. The Internet is based on the number of protocols and services. It is first of all TCP/IP protocol. HTTP protocol is used to retrieve a hypertext, graphics, audio and video and other media content. SMTP/POP3 allows to send and to receive e-mail. XML/web services give a great opportunity for developers to the powerful client-server applications.

In many developing countries the Internet may provide businessmen with a reliable alternative to the expensive and unreliable telecommunications systems of these countries. Commercial users can communicate over the Internet with the rest of the world and can do it very cheaply. When they send e-mail messages, they only have to pay for phone calls to their local service providers, not for calls across their countries or around the world. But who actually pays for sending e-mail messages over the Internet long distances, around the world? The answer is very simple: a user pays his service provider a monthly or hourly fee. A part of this fee goes towards its costs to connect to a larger service provider. And a part of the fee got by the larger provider goes to cover its cost of running a worldwide network of wires and wireless stations.

However, there are some problems in the Internet. The most acute one is security. When you send an e-mail message to somebody, it can travel through many different networks and computers. The data is constantly directed towards its destination by special computers called routers. Because of this, it is possible to get into any computer along the route, intercept and even change the data. In spite of the fact that there are many strong encoding programs available nearly all the information being sent over the Internet is transmitted without any form of encoding, i.e. “in the clear”

People use the Internet for different purposes. It can be used in business for providing access to complex databases; businessmen can conduct transactions and negotiations over the Internet. With the Internet it is possible to get information on nearly all the subjects, so it is very helpful for students in their study. You can also do research, download music, play interactive games, shop, talk in chat rooms and communicate with your friends using e-mail. The possibilities of the internet seem to be unlimited.
