Computers
Computer is an electronic device that can receive a program (a set of instructions) and then carry out this program by calculating numerical information.
The modern world of high technology is possible mainly due to the development of the computer. Computers have opened up a new era in manufacturing by means of automation, and they have enhanced modern communication systems.
Personal Сomputers
Personal computers also called microcomputers or home computer. The most compact are called laptops. They are portable and work on build-in batteries. Personal computers are designed for use at homes, schools, and offices. At home they can be used for home management (balancing the family finances, for example) and for playing computer games, watching films or listening to music. Schoolchildren can use computers for doing their homework and many schools now have computers for independent learning and computer-literacy studies. In the office personal computers may be used for word processing, bookkeeping, storage and handling of necessary information.
Personal computers were made possible by two technical innovations in the field of microelectronics: the integrated circuit, or IC, which was developed in 1959 and the microprocessor that first appeared in 1971 the IC permitted the miniaturization of computer-memory circuits, and the microprocessor reduced the size of a computer’s CPU to the size of a single silicon chip. Because a CPU calculates, performs logical operations, contains operating instructions, and manages data flows, a complete microcomputer as a separate system was designed and developed in 1974.
In 1981, IBM Company offered its own microcomputer model, the IBM PC that became a necessary tool for almost every business. The PC’s use of a 16-bit microprocessor initiated the development of faster and more powerful personal computers, and its use of an operating system that was available to all other computer makers led to a standardization of the industry. In the mid – 1980s, a number of other developments were especially important for the growth of personal computers. 0ne of these was the introduction of a powerful 32-bit CPU capable of running advanced operating systems at high speeds.
Another innovation was the use of conventional operating systems, such as UNIX, OS/2 Windows. The Apple Macintosh computers were the first to allow the user to select icons – graphic symbols of computer functions – from a display screen instead of typing commands. New voice-controlled systems are now available, and users are able to use the words and syntax of spoken language to operate their personal computers.

4. Переведите предложения. Определите верные они или нет, если нет, найдите в тексте правильный вариант ответа:
1) Computer is made of electronic components so it is referred to as electronic device. 2) Computer has no intelligence until software is loaded. 3) There are four elements of computer system: hardware, software, diskettes and data. 4) Without software instructions hardware doesn’t know what to do. 5) The software is the most important component because it is made by people. 6) The user inputs data into computer to get information as an output.
