Third Generation Of Computers

Third Generation of Computers - Circuits - 

(1965  – 1975  )

    Integrated circuits (IC) were used instead of separate

 transistors

    A single chip may contain thousands of transistors

    IC was invented by Robert Noyce and Jack S Kilby in   

 1958-59

    Smaller in size, faster, more reliable and less expensive

 compared to older generation computers

    Few examples are IBM 360, IBM 370, UNIVAC 1108,

 UNIVAC AC 9000, PDP-8, PDP-11, ICL 2900 etc.

    Time for calculation reduced to nanoseconds

    Programming languages were higher level languages like

 BASIC.

    Large magnetic tapes or discs were used to store data

    Magnetic tape, keyboard, printer, monitor e.t.c were the

 input and output devices.
