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
