Discuss about how the development of the pcs has extended the use of computers in presents days

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. 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 3 November 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 ". [1]

In 1968, 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". [2] This advertisement was deemed too extreme for the target audience and replaced with a much drier ad for the HP 9100A programmable calculator. [3][4]

Over the next seven years, the phrase had gained enough recognition that

Byte magazine referred to its readers in its first edition as "[in] the personal computing field", [5] 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." [6] In 1977, three new pre-assembled small computers hit the markets which Byte would refer to as the "1977 Trinity" of personal computing. [7] The Apple II and the PET 2001 were advertised as personal computers,[8][9] while the TRS-80 was 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. [10]

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.
