Fundamental of Computer (Part 3)

 Generation of computer

1st Generation (1940-1956)

• 1st Generation computer used Vacuum tube for electricity & magnetic drum is used for storage data
• The size of the compute is very big
• more heat generated 
• ENIAC & UNIVAC are the Example of 1st generation computer .

2nd Generation ( 1956-1963 )

•  In Second Generation of computer replace the vacuum tube and used Transistor for electricity 
• less heat generated.
• faster than first generation of computer
• COBOL & FORTRAN are language used by in this generation computer.

 3 Generation  (1964-1971)

• 3 rd Generation computer mainly based on IC (integrity cir cute )
• less heat generated than 1st and 2nd generation
• punch card is used for printing

4th Generation (1970-present day)

• Microprocessor based on
• very fast
• less heat generated
• no ac requirement 
• high label language supported  

5th Generation (1970--present day)

• VLIC based

Artificial Intelligence supported
