(詳細はHistory of computing hardware (1960s–present)を参照) The history of the personal computer as mass-market consumer electronic devices effectively began in 1977 with the introduction of microcomputers, although some mainframe and minicomputers had been applied as single-user systems much earlier. 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. After the development of the microprocessor, individual personal computers were low enough in cost that they eventually became affordable consumer goods. Early personal computers – generally called microcomputers– were sold often in electronic kit form and in limited numbers, and were of interest mostly to hobbyists and technicians. ==Etymology== An early use of the term "personal computer" appeared in a November 3, 1962, ''New York Times'' article reporting John W. Mauchly's vision of future computing as detailed at a recent meeting of the Institute of Industrial Engineers. Mauchly stated, "There is no reason to suppose the average boy or girl cannot be master of a ''personal computer''". Six years later a manufacturer took the risk of referring to their product this way, when Hewlett-Packard advertised their "Powerful Computing Genie" as "The New Hewlett-Packard 9100A personal computer". This advertisement was deemed too extreme for the target audience and replaced with a much drier ad for the HP 9100A programmable calculator. Over the next seven years the phrase had gained enough recognition that when ''Byte'' magazine published its first edition, it referred to its readers as "() the ''personal computing'' field", and ''Creative Computing'' defined the personal computer as a "non-(time)shared system containing sufficient processing power and storage capabilities to satisfy the needs of an individual user." Two years later, when what ''Byte'' was to call the "1977 Trinity" of pre-assembled small computers hit the markets, the Apple II and the PET 2001 were advertised as ''personal computers'', while the TRS-80 was a described as a microcomputer used for household tasks including "''personal'' financial management". By 1979 over half a million microcomputers were sold and the youth of the day had a new concept of the personal computer. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「History of personal computers」の詳細全文を読む スポンサード リンク
