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.
Transcript of Computers' History Timeline
1942Mark 1, First
electromechanical computer, using
mechanical devices, weighed 5 tons, it used about
750,000 parts
1946ENIAC, First Electronic
High-Speed, General-Purpose
Computer Using Vacuum
Tubes
1951LEO &
UNIVAC, First commercial automatic computers
1943Electronic
vacuum tubes, Controlling
electric current through a vacuum
in a sealed container
1949EDSAC & EDVAC,
First stored-program computers
1951 – 1958Were used vacuum tubes
as main logic element, punch cards (external) and rotating magnetic
drums (internal) to stare data, and compilers to
transform codes.
1959 – 1963Were used transistors
(with semiconductors) as main logic element and magnetic tape and disks (external), and magnetic cores (internal) to store
data.
1964 – 1979 Were used integrated
circuits as logic element, and magnetic
core internal memories began to give way to metal oxide semiconductor (MOS) memory. They used silicon-
backed chips.
1977Apple ][, first highly
successful mass-produced personal
microcomputer, designed by Steve
Wozniak.
1979 – PresentIntegrated circuits became
large-scale and very large-scale (LSIs and VLSICs); memory,
logic, and control circuits (an entire CPU) were in
microprocessors; they appeared home-use PC’s; language software are very easy.
1940 Onwards
1984First Apple Mac
(Macintosh), targeted mainly at the home, education, and creative professional
markets, by Apple Inc.
1981IBM PC (personal computer), and
MS-DOS (Microsoft Disk Operating System), was developped.
BeyondNow, they’re being developed
artificial intelligence, applications, parallel
processing, superconductors, quantum computation,
nanotechnology, etc., to improve computers, and they
are more and more technological.
