COMPUTER EVOLUTION (Start of the Generation)

First Generation Second GenerationThird GenerationFourth GenerationFifth Generation

FIRST GENERATION Vacuum tube technology EDVAC – Electronic Discrete Variable Automatic Computer UNIVAC – Universal Automatic Computer

SECOND GENERATION TRANSISTOR ERA

- invented by William Shockley, John Bardeen and Walter Brattain of Bell Laboratories.

- Texas Instruments improve it.

THIRD GENERATION SILICON CHIP ERA

- mini computer by Digital Equipment Inc.(1962) - IBM 360 series(1964).

- FORTRAN (Programming Language) (1956). - COBOL (Programming lang.)- Grace Hopper (1959).

FOURTH GENERATION VLSI & ULSI (Very Large Scale Integrated Circuit and Ultra Large Scale

Integrated Circuit)

- intel 4004 chip (1971) - Personal Computer by IBM (1981) - Macintosh introduced GUI (Graphic User Interface)

- LAN and WAN - WWW (World Wide Web)

FIFTH GENERATION (1990-present) Intelligent Robots Intelligent Systems Voice Recognition Dynamic Language Translator Dual Core, Quadro Core Intel Core i7
