Generation of ComputersBased on the characteristics of various computers developed from time to time, they are categorized as generation of computers.

First Generation ComputersTime Period : 1951 to 1959 Technology : Vacuum TubesSize : Very Large System Processing : Very Slow

Characterized By:- Magnetic Drums Magnetic Tapes Difficult to program Used machine language & assembly languageFirst Generation Computers

Second Generation Computers

Time Period : 1959 to 1963 Technology : TransistorsSize : Smaller Processing : FasterCharacterized By:- Magnetic Cores Magnetic Disk Used high level language Easier to program

Second Generation Computers

Third Generation ComputersTime Period: 1963 to 1975Technology: ICs (Integrated Circuits) Incorporated many transistors & electronic circuits on a single chipSize: Small as compared to 2nd generation computersProcessing: Faster then 2nd generation computers

Characterized by:- Minicomputers accessible by multiple users from remote terminals.

IC (Integrated Circuit)

Fourth Generation ComputersTime Period: 1975 to TodayTechnology: VLSI (Very Large Scale Integration) Incorporated many millions of transistors & electronic circuits on a single chipSize: Small as compared to first generation computerProcessing: Faster then first generation computer

Characterized by:The personal computer and user friendly micro-programs, very fast processor chip high level language, OOP (Object Oriented Programming)

VLSI (Very Large Scale Integration)

Fifth Generation ComputersTime Period: Future Technology Technology: AI (Artificial Intelligence)

Fifth Generation ComputerAI (Artificial Intelligence)
