1.      It occupy minimum space

2.      Minimum 2 or 1 hardware engineers

3.      The system works life long

DISADVANTAGES:-

1.      Current power waste

2.      It’s duration era 1975 to 1995

5^th GENERATION :- Laptop or Bio cells

Advantages :-

1.       It occupy a slate space

2.      Minimum one hardware engineer

3.      The system work life long

4.      It’s duration era 1995 onwards

TYPES OF COMPUTERS :-  Totally they are four types of computers. They are-

1.      Super computer

2.      Main frame computer

3.      Mini frame computer

4.      Micro frame computer

1.     SUPER COMPUTERS :- It is  highest computer having a good configuration

FOR EXAMPLE- Rockets or etc

2.     MAIN FRAME COMPUTERS :- Main frame computer is a highest computer having a good configuration like P4 systems

FOR EXAMPLE- USES- This system are used in banks, hotels, school, collages and institutes   

3.     MINI FRAME COMPUTERS :-  Mini frame computers is used up to specific task like D.N.S ( Domain Naming System ) and D.H.C.P ( Dynamic Host Configuration Products )

        FOR EXAMPLE- This systems will used up to limited networking 

  2^nd  GENERATION:   In 2 generation there was transistors.

Advantages:

 Batter then first generation.

1. It occupy a half space.

2. Normal heat was generated.

3. Minimum 4 or 5 hardware engineers.

4. The system works for few months.

Disadvantages:

1.      A/c Requirement.

2.      Current waste.

3.      Money waste.

4.      Its derision era 1955 to 1965.

3 .GENERATION: ITS Integrated circuits.

1.      It occupy quarter space.

2.      Minimum 3 to 4 hardware engineers.

3.      The system works for few years.

DISADVANTAGES :-

1.      Normal heat was generated

2.      A/C requirement

3.      Current waste

4.      Money waste

5.      It’s derision era 1965 to 1975

4.GENERATION  V.L.S.I.C ( Very Large Scale Integrated Circuits )

Advantages :-

 Better than 1^st  and 2rd  are 3^rd generations

DEFINITION OF COMPUTER:

Computer is an electronic deride which taken the data store. It process it and gives the result finally its stored in its memory its information is very speed .

GENERATIONS OF COMPUTERS:

To tamely there are 5 generations.

1^st GENERATION: In 1 generation there are 18,000 vacuum tubes.

Advantages:

1.    It occupy a lot of space.

2.    Very big heat was generated.

3.    A/c – Requirement.

4.    Current waste.

5.    Money waste.

6.    Minimum 6 or 7 hardware engineers.

7.    The system works for few days.

8.    Its derision era 1945 to 1955.
