GENERATION OF COMPUTER

THE WORD GENERATION INDICATE A STATE OF IMPROVEMENT IN THE PRODUCT DEVELOPMENT PROCESS WITH EACH NEW GENERATION OF COMPUTER.

THEIR FIVE GENERATION OF COMPUTER:-

FIRST GENERATION:- (1940-1956)  = VACUUM TUBE 

• They generate a lot of heat.
• They consumed a lots of electricity.
• They were very bulky in size.
• Vacuum tube use to filaments that that had limited life.
• This computer needed constant maintenance because of the low main time failure.
• This computer had limited commercial use they where difficult to program. 
• They where expensive.

SECOND GENERATION:- (1956-1963) = TRANSISTORS

 

• They consume less electricity and thus generate less heat as compare to the first GENERATION computer.
• They where faster, cheaper, smaller and more reliable then first generation computer.
• They could be program using assembly language and high level language.
• These computer had faster memory and lager secondary memory. 
• These computer where manufacture by using Transistors which had to assemble manual.
• This made commercial production of computers difficult and expensive.

Ex:- COBOL, FORTRAN, ALGO, & SNOBOL

1.  COBOL:- COmmon Business-oriented language.
2. FORTRAN:- Formula, Translation/ Translator.
3. ALGOL:- Algorithmic Language.
4. SNOBOL:- StriNg Oriented and Symbolic Language.

THIRD GENERATION:- (1964-1971)= Integrated Circuit 

• They were faster they second generation computer and could preform 1 million transaction/second.
• They were smaller cheaper and more reliable then their predecessors.
• These computer had faster and larger primary memory and secondary storage.
• Third generation computer were whitley use for scientific as well as business application.
• During this generation of computer , standardization existing high level long and invention of new high level long happend.
• These computers were difficult to maintain they got heated very quality.

Ex:- PL/I  and BASIC 

FOURTH GENERATION:- (1971-1989) = Microprocessor.

Intel 4004 was first microprocessor by Intel corporation (USA) i 1971 for small purpose.

It was a 4 bits microprocessor.

• Ones they consume less electricity and generate less heat they had faster and longer primary memory and secondary storage.
• They cloud be use as general purpose computer. 

Ex:- MsDos, Microsoft OS, Unix, apple,etc

FIFTH GENERATION:- (1990-Today)= 

• 5th generation computer are completely based on the new concept of artificial intelligence (AI).
• Gaming:- PUBG, COC, 8 ball pool, GTA ,Asphalt, etc
• Expert system :- medical diagnosis, Nuclear
•  Natural language Google now, cortana, siri.
• Robotics:- Arduino, etc
