History of Personal Computer
Prior to the Personal Computer (acronym PC), computers were designed for large organization who attached thin terminals for multiple users to a single large computer whose resources were shared among all users. The advent of the personal computer (PC), they break up the tradition of terminals computing. By the late 1980s, technology advances made it feasible to build a small computer that an individual could own and use.
The personal computer began to be wide spread in the 1980s. The first was expensive, work late and had little capacity seen with today's eyes. History shows that they had their antecedents in particular as calculating machines. It was the development of an effective operating system and a user friendly interface which gave impetus to the development and let them be word processors.
According to the Computer History, the first "personal computer" was the Kenbak-1, launched in 1971. Had256 bytes of memory and was advertised in Scientific American for $750, however, did not have CPU and was, like other systems of this era, designed for educational use.
Uses of Personal Computers
Personal computer (PC) is used for Work with word processing, Internet communications, and sound compositions and also for DTP. The PC is a most valued piece of technology around the world. The data processing capabilities of PC have added to their usage.
