1.2. Work in pairs or small groups. How would you describe what a computer is to someone who:
knows nothing about computers?
knows quite enough about computers?
1.3. Now read the text and describe a computer using the key vocabulary in bold type.
Technically, a computer is a programmable machine. Today, however, the term is most often used to refer to the desktop and laptop computers that most people use. When referring to a desktop model, the term "computer" technically only refers to the computer itself – not the monitor, keyboard, and mouse. Still, it is acceptable to refer to everything together as the computer. If you want to be really technical, the box that holds the computer is called the "system unit".
Some of the major parts of a personal computer (or PC) include the motherboard, CPU, memory (or RAM), hard drive, and video card. While personal computers are by far the most common type of computers today, there are several other types of computers. For example, a "minicomputer" is a powerful computer that can support many users at once.
A "mainframe" (1) is a large, high-powered computer that can perform billions of calculations from multiple sources at one time. Finally, a "supercomputer" (2) is a machine that can process billions of instructions a second and is used to calculate extremely complex calculations.
(1) mainframe базовое вычислительное устройство; большой

(2) supercomputer суперкомпьютер; сверхбыстродействующая ЭВМ;
сверхбольшая ЭВМ
