Generation Of Computer And Their Advantages and Disadvantages

with 7 Comments

1. First Generation Computer

The first generation of computer was between 1945 to 1955. The main element of this computer ware “Vacuum Tube”. Their memories were build of liquid mercury and magnetic drums. These

Advantages of First Generation Computer

1) This type of computers is simple and stores information.

Disadvantages of First Generation Computer

1) Large size. So was not able to carry.
2) This computer uses more electricity.
3) Need cold weather.
4) Most costly machine.

Language of First Generation of Computer

1) Machine Language
2) Assembly Language

Example of First Generation of Computer

1) Electronic Delay Storage Automatic Computer (EDSAC)
2) Electronic Discrete Variable Automatic Computer (EDVAC)
3) Electronic Numerical Integrator And Calculator (ENIAC)
4) Mark-I


2. Second Generation Computer

This computer used in 1956 to 1964. The main element of this computer was “Transistors” and used “Magnetic Cores” for Memories. William Shockley, John Bordin and Walter Brattain invented Transistors.

Advantages of Second Generation Computer

1) More speed than First Generation computer.

2) Size smaller than First Generation computer.

3) More reliable than First Generation computer.

4) Save more electricity than First Generation computer.

5) Low cost than First Generation computer.

Disadvantages of Second Generation Computer

1) Need cold weather.

2) Need maintainance earlier.

Language of Second Generation of Computer

High level Language, Like as- BASIC, COBOL, ALGOL, FORTRAN etc.

Example of Second Generation of Computer

IBM-1401, IBM-1620, IBM-7000, NCR-304 etc.

3. Third Generation Computer

This computer used in 1965 to 1975. The main element of this computer was “Integrated circuits” (I.C) and the first operating system.

Advantages of Third Generation Computer:

1) More reliable than the first and second generation computer.

2) Smaller than first and second generation.

3)  Save more electricity than first and second generation computer.

4) These computers Produce low heat than first and second generation.

Disadvantages of Third Generation Computer:

1) Need cold weather.

2) The functions of this computer are critical compare to first and second generation.

Language of Third Generation of Computer:

New FORTRAN, New COBOL, PASCAL.

Example of Third Generation of Computer:

IBM 360, IBM 370, ICL 2900, CDC 1700 etc.

4. Fourth Generation Computer

This computer used in 1975 to 1984. The main element of this computer was “Chips” (LSIC– Large Scale Integrated Circuit and VLSIC– very Large Scale Integrated Circuit ).

Advantages of Fourth Generation Computer:

1) Very small Size than  first, second and third generation Computer. So very easy to carry.

2)  More storage capacity than first, second and third Generation.

3) Save more electricity than first, second and third Generation .

4) No need to maintain earlier.

Disadvantages of Fourth Generation Computer:

1) The functions of this computer are more critical than first, second and third Generation.

2) The used softwares are very critical.

Language of Fourth Generation of Computer:

C, C++, SQL, Word etc.

Example of Fourth Generation of Computer:

DEC-10, IBM-4341, PRP-II , APPLE-II etc.

5. Fifth Generation Computer

This computer used in 1985 to Now. The main element of this computer is “Knowledge Information Process System”.

Advantages of Fifth Generation Computer:

1) This type of computer is versatile device by which we can perform various types of programme.

2) Low cost than first, second and third generation Computer.

3) High speed than first, second and third generation Computer.

4) This computer have artificial intelligence.

Language of Fifth Generation of Computer:

MS Office , Java etc.

Example of Fifth Generation of Computer:

Desktop, Laptop, Note Book, Ultra Book, Chrome Book.
