ENIAC (/ ˈ ɛ n i æ k /; Electronic Numerical Integrator and Computer) [1] [2] was the first programmable, electronic, general-purpose digital computer, completed in 1945. [ 3 ] [ 4 ] Other computers had some of these features, but ENIAC was the first to have them all.
The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1970s. A personal computer is one intended for interactive individual use, as opposed to a mainframe computer where the end user's requests are filtered through operating staff, or a time-sharing system in which one large processor is shared by many individuals.
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 ...
Colossus is thus regarded [2] as the world's first programmable, electronic, digital computer, although it was programmed by switches and plugs and not by a stored program. [ 3 ] Colossus was designed by General Post Office (GPO) research telephone engineer Tommy Flowers [ 1 ] based on plans developed by mathematician Max Newman at the ...
Desk-size computer made by Librascope; bit-serial drum machine with only 113 tubes, along with 1,450 diodes. [15] Ferranti Pegasus: 1956 38: Vacuum tube computer with magnetostrictive delay line memory intended for office usage. Second oldest surviving computer in the world. [16] RCA BIZMAC: 1956 6: RCA's first commercial computer, it contained ...
The UNIVAC I (Universal Automatic Computer I) was the first general-purpose electronic digital computer design for business application produced in the United States. It was designed principally by J. Presper Eckert and John Mauchly , the inventors of the ENIAC .
It's difficult to imagine life today without computers, but the personal computer was barely a reality just 33 years ago. On August 12th, 1981, IBM introduced their first PC model, also known as ...
Their first transistorized computer, and the first in the world, was operational by 1953, [146] and a second version was completed there in April 1955. [146] The 1955 version used 200 transistors, 1,300 solid-state diodes, and had a power consumption of 150 watts. However, the machine did make use of valves to generate its 125 kHz clock ...
