The term "fifth generation" was chosen to emphasize the system's advanced nature. In the history of computing hardware, there had been four prior "generations" of computers: the first generation utilized vacuum tubes; the second, transistors and diodes; the third, integrated circuits; and the fourth, microprocessors. While earlier generations ...
The first digital electronic computer was developed in the period April 1936 - June 1939, in the IBM Patent Department, Endicott, New York by Arthur Halsey Dickinson. [35] [36] [37] In this computer IBM introduced, a calculating device with a keyboard, processor and electronic output (display). The competitor to IBM was the digital electronic ...

Third-generation computers were offered well into the 1990s; for example the IBM ES9000 9X2 announced April 1994 [30] used 5,960 ECL chips to make a 10-way processor. [31] Other third-generation computers offered in the 1990s included the DEC VAX 9000 (1989), built from ECL gate arrays and custom chips, [32] and the Cray T90 (1995).
Computers built after 1972 are often called fourth-generation computers, based on LSI (Large Scale Integration) of circuits (such as microprocessors) – typically 500 or more components on a chip. Later developments include VLSI (Very Large Scale Integration) of integrated circuits 5 years later – typically 10,000 components.

The original GUI was developed on the Xerox Alto computer system at Xerox Palo Alto Research Center in the early 1970s and commercialized by many vendors throughout the 1980s and 1990s. Since the late 1990s, there have been three operating systems in widespread use on personal computers: Apple Inc.'s macOS, the open source Linux, and Microsoft ...
