Almost every home has a computer. Some need it for work, and others for communication and leisure. In 1946, the world's first computer was assembled in the USA, which was intended for the needs of the army and was huge.
Its construction cost about half a million dollars. They worked on it for about three years. It weighed 28 tons. And the first computer was cooled by aircraft engines. A personal computer has the following parts: motherboard, power supply, RAM, processor, video adapter, hard disk, disk drive, expansion cards.
The process of interaction between a person and a PC is more than 40 years old. Until recently, only engineers, mathematicians – programmers, and operators could participate in this process. Now the situation has changed, the role of the user can be not only a specialist, but also any person, be it a schoolboy or a housewife, a doctor or a teacher, a worker or an engineer.
