The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1970s. A personal computer is one intended for interactive individual use, as opposed to a mainframe computer where the end user's requests are filtered through operating staff, or a time-sharing system in which one large processor is shared by many individuals.
A hobby-type computer often would have required significant expansion of memory and peripherals to make it useful for the usual role of a factory-made home computer. School computers usually had facilities to share expensive peripherals such as disk drives and printers, and often had provision for central administration.

A different model of computer use was foreshadowed by the way in which early, pre-commercial, experimental computers were used, where one user had exclusive use of a processor. [36] Some of the first computers that might be called "personal" were early minicomputers such as the LINC and PDP-8 , and later on VAX and larger minicomputers from ...
