A computer is a machine with an intricate network of electronic circuits that operate switches or magnetize tiny metal cores. The switches, like the cores, are capable of being in one of two possible states, that is, on or off; magnetized or demagnetized. The machine is capable of storing and manipulating number, letters, and characters. The basic idea of a computer is that we can make the machine do what we want by inputting signals that turn certain switches on and turn others off, or that magnetize or do not magnetize the cores. The basic job of computer is the processing of information. Three basic steps are involved in the process. First, data is fed into the com puter’s memory. Then, when the program is run, the computer performs a set of instructions and processes the data. Finally, we can see the results (the output) on the screen or in printed form. Information in the form of data and programs is known as softw are, and the electronic and mechanical parts that make up a computer system are called hardw are. Computers have many remarkable powers. However, most computers, whether large or small have three basic capabilities. First, computer has circuits for performing arithmetic operations, such as: addition, subtraction, division, multiplication and exponentiation. Second, computer has a means of communicating with the user. After all, if we couldn’t feed information in and get results back, these machines wouldn’t be of much use. However, certain computer (commonly minicomputers and microcomputers ) are used to control directly things such as robots, aircraft navigation systems, medical instruments, etc. A standard computer system consists of three "main sections: The centre processing unit (C PU ), the main memory and the peripherals. Task 1 Decide whether the follow ing statements are true or fa lse (T/F) by referring to the inform ation in the text. Then make the necessary changes so that the fa lse statem ent becomes true. information to do so. 10 f 2. All computers accept and process information in the form of instructions and characters. 3. The information necessary for solving problems is found in the memory of the computer. 4. Not all computers can perform arithmetic operations, make decisions and communicate in some ways with the user. 5. Computers can still be useful machines even if they can’t communicate with the user. 6. There are many different devices used for feeding information into a computer. 7. There aren’t as many different types of devices used for giving results as there are for accepting information. 8. Computers can make any type of decision they are asked to. 9. Computers can work endlessly without having to stop to rest unless there is a breakdown. LISTENING AND WRITING Task 2 Before listening, answer these questions 1. Have you got a computer at home, school or work? What kind is it? 2. How often do you use it? What do you use it for? Task 3 Listen to these people talking about how they use com puters at work and write each speaker's jo b in the table.

LANGUAGE STUDY The passive Passives are very common in technical writing where we are more interested in facts, processes, and events than in people. We form the passive by using the appropriate tenses of the verb to be followed by the past participle of the verb we are using. Exam ples Active 1. We sell computers, (simple present) 2. Babbage invented ‘ The Analytical Engine’, (simple past) Passive 1 Computers a re sold 2 “The Analytical Engine” was invented in 1830. ■ ■ ■ ■■ - u \ - j 13 Task 8 Read the text below, which describes the insurance com pany's procedure fo r dealing with PC-users' problems.
