Who invented the first computer in the world and when?
The first electronic digital computer was the ABC built by John V. Atanasoff and Clifford Berry in 1940 at Iowa State University. Several of its ideas were incorporated into the ENIAC which ran from 1945-1955 and is considered the first functionally useful electronic digital computer. The patent for ENIAC was awarded to Atanasoff by court order in 1974. The first commercially available electronic computer in the USA was the UNIVAC I, bought by and delivered to the US Census Bureau in 1951. One of the earliest personal computers was the Intellec 4 by Intel, using their first commercially produced microprocessor – the four-bit 4004. The Altair built by MITS was the first commercially successful personal computer and the computer Bill Gates and Paul Allen wrote Microsoft’s (then known as Micro-Soft) first software product for – “BASIC for the Altair.” Douglas Engelbart, then at the Stanford Research Institute (SRI), demonstrated a mouse-keyboard component at a computer conference in 1968
