GENERATION OF COMPUTER
Dipu Thomas Joy
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
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
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
FOURTH GENERATION (1971-PRESENT) MICROPROCESSORS
Microprocessor Hard disk Ram Integrated circuits Operating system IBM introduced its first computer for the
home user, Gui technology More fastest,cheaper,less power conception Introduction of mouse
FIFTH GENERATION (PRESENT AND BEYOND) ARTIFICIAL INTELLIGENCE
voice recognition nanotechnology Touch screen Finger print recognition
