1 TOPIC: LIVING WITH A COMPUTER Plan: 1. Understanding of personal computer. 2. Basic devices of a personal computer 3. Additional devices of the personal computer

1. Understanding of personal computer.

• The first personal computer was created in 1973 in France by Nruohg Trohg Ti. The first masked personal computer was considered an electronic toy. This computer was perfected by the American company "Apple Computer" led by Steve Jobs in 1977, implemented a large set of programs and began to be released in mass. Since then, the computer has firmly established itself in our lives and has become the most modern means of information processing.
• A computer can be understood as a universal automatic device that provides rapid processing of information of various sizes and forms.

Currently, many modern computers are serving people directly. Their appearance is also different. But if we take a closer look at the devices that make them up (i.e. hardware), we will see that there are similarities in the devices of different categories of machines. Any computer hardware consists of basic and additional devices. Basic devices provide computer operation, additional devices extend the possibility of working with the computer.

• A computer (English: computer - "I calculate") is an automatic device that works according to a predetermined program. The same term as electronic calculator (EHM). However, in addition to performing computer calculations, its function is much wider. Several generations of computers can be shown in the development of EHMs. These generations differ from each other in terms of types of elements, constructive-technological features, logical structure, software support, technical details, ease of use of equipment. In the first generation of computers (Ural-1, Minsk-2, BSEM-2), the main element was an electronic lamp, so it occupied a very large space. Then a computer using transistors instead of a lamp (Razdan-2, M-220, Minsk-22, etc.), a computer using integrated circuits (IBM-360, 1BM-370, (USA), YESEVM (Russia), etc.), with a high degree of integration personal computers with built-in integrated circuits appeared.
