What is a personal computer? Personal computers (PC.) are small, relatively inexpensive computers for an individual user. Their price can be from a few hundred dollars to thousands of dollars. All are based on the microprocessor technology that enables manufacturers to put an entire CPU on one chip. Personal computers are used in business for word processing, accounting, desktop publishing. At home, the most popular use for personal computers is for playing games.

Then, in 1981, IBM (International Business Machines) made its first personal computer, known as the IBM PC. The IBM PC quickly became the most popular personal computer.
