CSIRAC (/ ˈsaɪræk /; Commonwealth Scientific and Industrial Research Automatic Computer), originally known as CSIR Mk 1, was Australia 's first digital computer, and the fifth stored program computer in the world. [1] It is the oldest surviving first-generation electronic computer [2] (the Zuse Z4 at the Deutsches Museum is older, but was ...
General Electric. RCA. Some examples of 1960s second generation computers from those vendors are: the IBM 1401, the IBM 7090/7094, and the IBM System/360; the Burroughs 5000 series; the UNIVAC 1107; the NCR 315; the CDC 1604 and the CDC 3000 series; the Honeywell 200, Honeywell 400, and Honeywell 800;
A vacuum-tube computer, now termed a first-generation computer, is a computer that uses vacuum tubes for logic circuitry. While the history of mechanical aids to computation goes back centuries, if not millennia, the history of vacuum tube computers is confined to the middle of the 20th century. Lee De Forest invented the triode in 1906.
700 pounds (320 kg) The Atanasoff–Berry computer (ABC) was the first automatic electronic digital computer. [1] Limited by the technology of the day, and execution, the device has remained somewhat obscure. The ABC's priority is debated among historians of computer technology, because it was neither programmable, nor Turing-complete. [2]
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 Z3 was a German electromechanical computer designed by Konrad Zuse in 1938, and completed in 1941. It was the world's first working programmable, fully automatic digital computer. [ 3 ] The Z3 was built with 2,600 relays, implementing a 22- bit word length that operated at a clock frequency of about 5–10 Hz. [ 1 ]
Vacuum-tube computers, now called first-generation computers, [ 1 ] are programmable digital computers using vacuum-tube logic circuitry. They were preceded by systems using electromechanical relays and followed by systems built from discrete transistors. Some later computers on the list had both vacuum tubes and transistors.
The EDVAC as installed in Building 328 at the Ballistic Research Laboratory. EDVAC (Electronic Discrete Variable Automatic Computer) was one of the earliest electronic computers. It was built by Moore School of Electrical Engineering, Pennsylvania. [1][2]: 626–628 Along with ORDVAC, it was a successor to the ENIAC.
