Computer Generation
− The earliest computers, developed in the
1940s and 1950s
− Made from valves and wire circuits
First Generation
ENIAC Computer
Atanasof-Berry Computer
− From the late 1950s to the early 1960s
− Based on transistors and printed circuits
Second Generation
− From the early 1960s to 1970
− Using integrated circuits and often sold as
families of computers, such as the IBM 360
series
Third Generation
ERMA - Electronic
Recording Method of
Accounting computer
processing system. ERMA
began as a project for the
Bank of America in an effort
to computerize the banking
industry.
Fourth Generation
− From the 1970s and still in use
− Using microprocessor
− Based on emerging microelectronic
technologies with high computing speeds
and parallel processing
− The development of very large-scale integration
(VLSI) technology, enables many more circuits
onto an integrated circuit (chip); produce far
more powerful computers
− currently under development
Fifth Generation
