History of Computers

A personal computer capability has changed greatly since the introduction of electronic computers. By the early 1970s, people in academic or research institutions had the opportunity for single-person use of a computer system . The introduction of the microprocessor, a single chip with all the circuitry that formerly occupied large cabinets, led to the proliferation of personal computers after about 1975. The peripherals reqiored for a computer such as keyboards, computer terminals, disk drives, and printers are developed in a sophisticated manner. Now a days, we cannot imagine an office, bank, architectural establishment, engineering departments, even hospitals and residences without a computer. Even local area networking, originally a way to allow business computers to share expensive mass storage and peripherals, became a standard feature of the personal computers used at home.
