Task I 1. Read and translate the text. Computers A computer is an electronic machine that performs input, processing, storing, and output according to programmed instructions to carry out specific tasks. Computers were used primarily to do arithmetic computations (вычисления, расчеты), hence (отсюда) the term ‘computer’. A modern computer works in a similar way. Information is input into a computer with the help of a keyboard or a mouse. Then the computer processes the input, stores the result, and displays the result with the help of monitor, speaker, printer, or other output devices. There are different types of computer. The word you choose to describe them usually depends on the size. A PC (personal computer) is a computer which you use at home or in an office. PCs are also sometimes called desktop computers or just desktops. They usually have four separate parts: the computer itself, the screen, the mouse and the keyboard. The screen or monitor is the thing you look at, the keyboard is for typing, and the mouse is for clicking. A laptop is a smaller computer. It's called a laptop because it fits on your lap (your knees). It doesn't usually have a separate keyboard and screen. You often use a laptop when you need to move around because it's easy to carry. You can also have a hand-held computer. This is a very small computer that can be held in one hand. 2. Complete the sentences using the information from the text. a.
