On 1943 ENIAC started building at 1943. Then on 1945 ENIAC was completed. On February 14, ENIAC was introduced.
-
The UNIVAC was the first commercial and bussines computer. As ENIAC was very big, UNIVAC was smaller than ENIAC.

The Second Generation of Computers used Transistors.
-
The Transistor was invented in 1947 but it came out in the 1950s. The transistor replaced the Vacuum Tubes. It was used in the second generation computers.

The Fourth Generations Computers used Microproccessors
-
Microprocessors was invented by Marcian Hoff, Stanley Mazor, and Masatoshi Shima in 1972. The forth generation computersd used Microprocessors. Microprocessors was like thousands of integrated cicuts fit in one single silicon chip.
