Вопрос № 1006895 - Английский язык

Personal computers (or microcomputers) were made possible by two technical innovations in the field of microelectronics: the integrated circuit, or IС, which was developed in 1959 and the microprocessor that first appeared in 1971. The IС 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.
