The concept of a personal computer (micro and -micro EHM) began to spread widely from the end of the 70s of the 20th century. In the next generations of personal computers, microelectronics and biocircuits were used; their size is reduced to the size of a book, and their mass is 3 .5 kg. In 1981, IBM began to develop more advanced models of the personal computer. Later, other companies created the PC with IBM, and Apple created the Macintosh (pronounced "Mackintosh") or simply "maki". At the beginning of the 21st century, there were tens of millions of personal computers, about 1 million EHMs (including several tens of superEVMs) in the world. Computers differ from each other in the composition and description of the components used to solve problems. A computer with powerful devices is used to solve complex problems, and a computer with a typewriter is used to print documents. Any computer consists of a system unit, a monitor and a keyboard. Other devices are connected as needed. The system block contains the important parts necessary for the operation of the computer (disk drive, Winchester - hard disk, microcircuits that perform logical operations), and the rest of the devices are connected to it.
