Computers' History Timeline

May 08, 2015



This is a timeline about computers' history starting at Mark 1, first electromechanical computer, going over electronic vacuum tubes, ENIAC, EDSAC, EDVAC, LEO, UNIVAC, Apple II or Apple ][, IBM PC, first Macintosh, and the different ages of computers' history.

  • 1.1942 Mark 1, First electromechanical computer, using mechanical devices, weighed 5 tons, it used about 750,000 partsBeyond1946 ENIAC, First Electronic High-Speed, GeneralPurpose Computer Using Vacuum Tubes1959 1963 1951 LEO & UNIVAC, First commercial automatic computersWere used transistors (with semiconductors) as main logic element and magnetic tape and disks (external), and magnetic cores (internal) to store data.19771981Apple ][, first highly successful massproduced personal microcomputer, designed by Steve Wozniak.IBM PC (personal computer), and MS-DOS (Microsoft Disk Operating System), was developped.Now, theyre being developed artificial intelligence, applications, parallel processing, superconductors, quantum computation, nanotechnology, etc., to improve computers, and they are more and more technological. Onwards1940194319491951 19581964 1979Electronic vacuum tubes, Controlling electric current through a vacuum in a sealed containerEDSAC & EDVAC, First storedprogram computersWere used vacuum tubes as main logic element, punch cards (external) and rotating magnetic drums (internal) to stare data, and compilers to transform codes.Were used integrated circuits as logic element, and magnetic core internal memories began to give way to metal oxide semiconductor (MOS) memory. They used siliconbacked chips.1984 1979 Present Integrated circuits became First Apple Mac large-scale and very large-scale (Macintosh), (LSIs and VLSICs); memory, targeted mainly at the logic, and control circuits (an home, education, and entire CPU) were in creative professional microprocessors; they appeared markets, by Apple Inc. home-use PCs; language software are very easy.
