कम्प्यूटर  के  जनरेशन पर संक्षिप्त टिप्पणी

GENERATION	YEAR	SWITCHING DEVICE	STORAGE DEVICE	SPEED	OPERATING SYSTEM	LANGUAGE	CHARECTERISTIC
FIRST	1940-56	Vacuum Tubes	Magnetic Drum	333 Micro Second	Batch OS	Machine Language(Binary 0s & 1s)	·        Fastest computing device ·        Generating large amount of heat ·        big room size
SECOND	1956-63	Transistor	Magnetic Core Technology	10 Micro Second	Time-Sharing,Multi Tasking OS	Assembly Language , High Level Language	·        more reliable & less hardware fail ·        generate less heat ·        small size as compare  to  previous
THIRD	1964-71	Intrigated Circuit(ICs)	Magnetic Core as Primary Storage Medium	100 Nano Second	Real Time System	High Level Language(FORTON,COBOL,ALGOL)	·        consume less power ·        highly sophisticated technology required
FOURTH	1971-85	Large Scale Integrated Circuit (LSI) Microprocessor	Semi Conductor Memory, Winchester	10 Pico Second	Time Sharing Netword , Gui interface	PASCAL,ADA,COBOL-74,FORTRAN IV	·        more reliable & portable ·        leads to better communication & resource sharing
FIFTH	1985-PRESENT & BEYOND	Super Large Scale Integrated	----	----	-----	----	·        parallel processing ·        intel microprocessor implemented
