Personal computer is a small, relatively inexpensive computer designed for an individual user. In price, personal computers range anywhere from a few hundred dollars to thousands of dollars AJI are based on the microprocessor technology that enables manufacturers 1 C to put an entire CPU on one chip. CPU stands for Central Processing Unit The reason the CPU is called a processor is because it can work with data it can do calculations; it can move data Businesses use personal computers for word processing, accounting, desktop publishing, and for running spreadsheet and database management applications. At home, the most popular use for personal computers is for playing games.
