The computer was never truly completed due to Atanasoff's departure from Iowa State University in 1942 to work for the United States Navy. [41] [42] Many people credit ABC with many of the ideas used in later developments during the age of early electronic computing. [43]
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.
