The document summarizes the five generations of computers from the first to the fifth generation. The first generation used vacuum tubes and were very large in size. The second generation used transistors and were smaller. The third generation used integrated circuits and were smaller still with multiple users accessing from remote terminals. The fourth generation used microprocessors and were very small with powerful and reliable processing. The fifth generation, still in development, will use artificial intelligence and nano technology.

2. GENERATION OF COMPUTER
• As the time passed, the device of more suitable and reliable
machine was need which could perform our work more quickly.
• During this time in the year 1946, the first successful electronic
computer called ENIAC (Electronic numerical integrator and
computer/calculator) was developed.
• It was the starting point of the current generation of the computer

• Technology : IC’s (Integrated circuits)
• Size : Smaller as compare to 2nd generation
• Processing : Faster then 2nd generation
Characterized By :
Mini computer accessible by
multiple users from remote
terminals

6. Fourth Generation Of Computer
• Time Period : 1971- Present
• Technology : Microprocessors
• Size : Very small size
• Processing : One million /ps (Best speed to read instructions)
Characterized By:
Microprocessor contains thousands of IC’s
More powerful and reliable from previous
Use fan for heat discharge
Portable computers

7. Fifth Generation Of Computer
• Time period : future
• Technology :AI (Artificial Intelligence),
Nano technology
They are still in development
The use of parallel processing and
superconductors is helping to make
artificial intelligence a reality
