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
