Question

tell information about 1, 2,3,4, and 5 generations of computer

Answer 1

Answer:

1st generation - Generates a lot of heat, Used Vaccum Tubes

2nd  Generation - Cheaper and faster than 1st generation computers. Used punch cards and magnetic cards to store data.

3rd Generation - Cheaper and faster than 2nd generation computers. Used intergrated circuits. the use of keyboard and monitor started in this generation.

4th Generation - Cheaper and faster than 3rd generation computers. Used processers.

5th Generation - It is still nascent stage of development

Explanation:

Answer 2

The computer of electronic age divided into five generation on basic of technology used by computer —

1st GENERATION -

1. Technology vacuum tube

2. Supported machine language only

3. Large space needed to store

4. Very costly

5. Ac needed to cool down

6. Consumed lot of electricity

7. Slow input and output device

8. Non portable

9. Constant maintenance required

10. Calculate data in millisecond

11. Examples: ENIAC, EDVAC, IBM-701, IBM-650

2nd GENERATION -

1. technology transistor

2. Magnetic core used in primary memory

3. Magnetic tape and magnetic disks as secondary storage device

4. assembly language

5. still very costly

6. Still ac needed to cool down

7. Size become smaller in comparison to first generation

8. punch card used as input device

9. more reliable comparison to first generation

10. Examples: IBM 1620, IBM 7094, CDC 1604, UNIVAC

3rd GENERATION -

1. Technology integrated circuit

2. IC is made of thousand of transistor

3. High level language like FORTRAN 2to4,COBOL

4. Generated very less heat

5. Smaller in size comparison to previous generation

6. Still costly

7. More reliable comparison to previous generation

8. only fan required to cool down

9. Portable

10. Example: IBM 360 series tdc 316

4th GENERATION –

1. Technology VLSI(Very large scale integrated circuit)

2. Portable

3. Very reliable

4. Computer started produced for business purpose

5. Cost decreased

6. Smaller in size

7. Keyboard and mouse were used as input device

8. Fast processing

9. Less power consumption

10. Example: dec 10,star 1000,apple, etc.

5th GENERATION –

1. Technology, ULSI(Ultra large scale integrated) circuit and artificial intelligence were used in future.

2. High level language like java, python,net, etc.

3. These were future generation computer.

4. Computer can understand spoken word and respond to surrounding.

5. Example: desktop,laptops ,chrome book.

Hope this helps!!

Have a great day ahead!!
