1. GENERATION OF
COMPUTER
Dipu Thomas Joy

2. FIRST GENERATION (1940-1956) VACUUM TUBES
 vacuum tubes
 magnetic drums for memory
 taking up entire rooms
 using a great deal of electricity
 only solve one problem at a time
 displayed on printouts.
 UNIVAC and ENIAC computers
 Used by scientist

4. SECOND GENERATION (1956-1963)
TRANSISTORS
 Transistors replaced vacuum tubes
 allowing computers to become smaller,
 smaller, faster, cheaper, more energy-efficient
 COBOL and FORTRAN
 magnetic drum to magnetic core technology.
 atomic energy industry,bussiness

6. THIRD GENERATION (1964-1971) INTEGRATED
CIRCUITS
 integrated circuit was the hallmark of the third
generation of computers
 silicon chips, called semiconductors
 drastically increased the speed and efficiency of
computers.
 keyboard and monitors and interfaced with
an operating system
 they were smaller and cheaper
