Unit 1 Computers origins
The first suggestion that a machine for mathematical computation could be built was made more than a hundred years ago by the mathematician Charles Babbage. We now realize that he understood clearly all the fundamental principles of modern computers. Babbage was born in Devonshire, England, 1792. He did not receive a good education, but he taught himself mathematics so well that when he went in Cambridge, he found that he knew more algebra than his tutor. At that time mathematics in Cambridge was still under the influence of Newton and was quite unaffected by the contemporary developments on the continent. Charles Babbage was outstanding among his contemporaries because he insisted on practical application of science and mathematics. For example, he wrote widely on the economic advantages of mass productions and on the development of machine tools. In 1812 he was sitting in his room looking at a table of logarithms which he knew to be full of mistakes, when an idea occurred to him of computing all tabular functions by machinery. Babbage constructed a small working model which he demonstrated in 1822. The Royal Society supported the project and Babbage was promised a subsidy. In 1833 he began to think of building a machine which was in fact the first universal digital computer, as the expression is understood today. Babbage devoted the rest of his life to an attempt to develop it. He had to finance all of the work himself and he was only able to finish part of the machine though he prepared thousands of detailed drawings from which it could be made. Babbage wrote more than 80 books and papers, bur he was misunderstood by his contemporaries and died a disappointed man in 1871. He tried to solve by himself and with his own resources a series of problems which in the end required the united efforts of two generations of engineers. After his death his son continued his work and built part of an arithmetic’s unit, which printed out its results directly on paper. Vocabulary

Computers today Yesterday’s computers were tools for scientists, mathematicians, and engineers. Today many businesses and organizations own computers although they have different types of computers and use them for different purposes. Hardly a day goes by when do not make a controlled business transaction. Each time we visit the bank, use a credit card, pay a bill or a ticket a computer lurks behind the scene, recording each transaction. Computers can process data in a fraction of the time it would take to perform the same jobs manually. They reduce the paperwork involved in these transactions and also reduce costs. No area of enterprise seems without computers nowadays. Scientists build computer models of airplane crashes in order to determine the ‘crash behavior’ of airplanes, which in turn helps aircraft designers plan safer seats, windows, and fabrics to decrease fire hazards during a crash. Ecologists use computers to monitor environmental problems like acid rain and suggest solutions. Engineers use computers to design replacement for the damaged bones. Educators use computers in the classroom to perform chemistry experiments that might otherwise be dangerous. There seems to be no limit to computer applications. Hard copy, modem, database, peripherals: all these words refer to a relatively new and rapidly changing technology – that of the computer. Computers are changing our language, and they are also changing us. No longer are computer expert the only people who interact with computers. Today the lives of most of us are affected by computers every day.

_________________________________________________________________________ Unit 3 What is a computer? Computer is device for processing information. Computer has no intelligence by itself and is called hardware. A computer system is a combination of four elements: · Hardware · Software · Procedures · Data/information Software are the programmes that tell the hardware how to perform a task. Without software instructions, the hardware doesn’t know what to do. The basic job of the computer is the form of instructions called programs and symbols called data. After that they perform various mathematical and logical operations, and then give the results (information). Computer is used to convert data into information. Computer is also used to store information in the digital form. Vocabulary: Device устройство Intelligence разум Hardware оборудование Software программы Processing обработка Procedures процедуры, операции to perform выполнять Manner манера, способ Various различные Purpose цель to convert превращать Data данные to store хранить Digital цифровой

Translate the text IMB (international business Machines) launched the PC in 1981. Improved versions quickly followed. The basic PC had just 64K (K=Kilobyte) of RAM. RAM is (R)andom (A)ccess (M)emory, the computer's built-it memory, used for holding the instruction programs, for working space, and working storage. The first PC had one floppy-disk drive. Floppy disks are a mean of electronically recording computer programs and computer output. The disks are “read” and “written to” in a disk drive. They are called “floppy” disks because, initially, they were. Today, huge-capacity storage disks are built into most computers. ______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 1.

Unit 4 What is hardware? The hardware- the devices composing a computer system. Computer hardware can be divided into four categories:
Input hardware Input hardware collects data and converts them into a form suitable for computer processing. The most common input device is a keyboard. It looks very much like a typewriter. The mouse is hand-held device connected to the computer by a small cable. As the mouse is rolled across the desktop, the cursor moves across the screen. When the cursor reaches the desired location, the user usually pushes a button on the mouse once or twice to give a command to the computer. Processing hardware
Processing hardware directs the execution of software instructions in the computer. The most common components of processing hardware are the central processing unit and main memory. The central processing unit (CPU) is the brain of the computer. It reads and interprets software instructions and coordinates the processing. Memory is the component of the computer in which information is stored. There are two types of computer memory: RAM and ROM. RAM (random access memory) is the memory, used for creating, loading and running programs. ROM (read only memory) is computer memory used to hold programmed instructions to the system. The more memory you have in your computer, the more operations you can perform. Storage hardware The purpose of storage hardware is to store computer instructions and date hardware. There are two types of output; soft copy and hard copy. Soft copy is information that is seen on a television-like screen, of monitor, attached to most computers. It is temporary; as soon as the monitor is turned off or new information is required, the old information vanishes. Hard copy is output printed in a tangible form such as on paper. It can be read without using the computer and can be conveniently carried around, written on, or passed to other readers. Vocabulary:
Keyboard клавиатура Mouse мышь to load загружать Instruction команда Error message сообщение об ошибки Input ввод Output вывод информации Button кнопка Memory память to create создавать Soft copy мягкая копия, изображение на экране Hard copy твердая копия, машинная (печатная) to attach подсоединяться, подключать Passive Voice Времена страдательного залога образуются при помощи вспомогательного глагола to be в соответствующем времени и причастия прошедшего времени (Past Participle) смыслового глагола. При спряжении глагола в страдательном залоге изменяется только глагол to be , смысловой же глагол имеет во всех временах одну и ту же форму – Past Participle. Следовательно, время определяется формой, в котором стоит глагол в страдательном залоге, определяется формой, в которой стоит вспомогательный глагол to be:
При образовании вопросительной формы вспомогательный глагол ставится перед подлежащим: Am I asked? Меня спрашивают? Shall I be asked? Меня спросят? Have I been asked? Меня спросили? When was the book written? Когда была написана книга? При образовании отрицательной формы Passive Voice частица not ставится после вспомогательного глагола: I am not asked. I shall not be asked. С модальными глаголами must, can (could), may (might), should, ought to, have to, be to пассивная форма образуется с помощью to be и Past Participle основного глагола. This work must be finished today. This report ought to be finished tonight. That room cannot be used as a classroom.

Unit 5 Software Not visible units the software. Software consists of the instruction to the computer that enable it to do things, such as finding the best sport to drill for oil or playing a competitive game of bridge. These computer instructions are also called programs.
Computers only do what they are told to do. Often, we want the computer to do the same thing again and again. So standard instructions – programs – are produced. First though, a computer needs to know where, within its built-in memory, to store information and how to work on it. This basic program is called an operating system (or disk operating system). One popular operating system, introduced with the IBM PC, is called MS-DOS (from (M)icro(S)oft (D)isk (O)preating (S)ystem). A recent development from MS-DOS lets you tell the computer what to do by “pointing” at things (words or pictures) on the screen. This easy to use system is called Windows. Once the computer has its operating instructions it can be programmed to do many other things. Popular computer programs include word processors, databases, spreadsheets and graphics: · Word processors produce the printed words – immaculately. · Databases store masses of information – for easy access. · Spreadsheets record and process numbers. · Graphics programs produce graphs and diagrams.

THE ORIGINS OF THE INTERNET Text Part I The Internet is a global computer network. Millions of people around the world use the Internet to search for and retrieve information on all sorts of topics, such as arts, business, humanities, news, politics, recreation and others. People communicate through electronic mail (e-mail), discussion groups, chat channels and other means of informational exchange. They share information and make commercial and business transaction. How did Internet get started? The Internet began in the late 1960s as an experiment by the U.S Department of Defense to see if a non-centralized network could be built to 'withstand the destruction of one or more of its parts. Unlike previous networks, this new network did not have a single central point. Instead, all sites on the network were interconnected. Out of this network came a protocol for linking computers together. A protocol is a set of standards for how network communication takes place. The protocol is called TCP/IP (Transmission Control Protocol/lnternet Protocol). This protocol is the standard that makes it possible for different computers all over the globe to talk to each other. The TCP/IP protocol is the foundation of the Internet.
Part II At first, the Internet was used solely by the US government, but soon universities and other institutions connected themselves to the Internet to communicate with one another and collaborate on projects. The Internet grew to connect hundreds or different sites all across the world. Each organization on the Internet was responsible for maintaining its part of the network, so the Internet was not owned or controlled by anyone organization. Today, the Internet connects up to 40 million people around the globe and is growing by as much as 10% per month. The Internet is like a system of roads, freeways, and bridges. The term " Information Superhighway" describes how the Internet works. From road in any city, you can get to almost any other road in any other. From your computer you can send all electronic mail message to icone sitting at a computer in Helsinki, Warsaw, or Moscow. Internet access companies or Internet Service Providers (lSP) vide physical connections that allow you to access the internet. These connections are called " POPs, ” which stands for " points of sence." Your computer uses a modem to dial into a POP, which connects you to the Internet. Once connected to a POP, you have access to all the resources of the Internet. Most ISP's will also supply you with software available for work in the Internet: a Web browser. Vocabulary:
to retrieve recreation humanities to share sole website department of defense to withstand site network communication TCP/IP (Transmission Control Protocol/Internet Protocol) ARPANET
Freeway Superhighway Internet Service Providers
