Transcript of Five Generations of Computer

Five Generations of Computer
First Generation
It was developed by two scientists Mauchly and Echert at the Census Department of United States in 1947.
Second Generation
The second generation computers used transistors. The scientists at Bell laboratories developed transistor in 1947. These scientists include John Barden, William Brattain and William Shockley. The size of the computers was decreased by replacing vacuum tubes with transistors. The examples of second generation computers are IBM 7094 series, IBM 1400 series and CDC 164 etc.
Third Generation
The Third generation computers used the integrated circuits (IC). Jack Kilby developed the concept of integrated circuit in 1958. It was an important invention in the computer field.
Fourth Generation
The fourth generation computers started with the invention of Microprocessor. The Microprocessor contains thousands of ICs. Ted Hoff produced the first microprocessor in 1971 for Intel.
Fifth Generation (now)
Scientists are working hard on the 5th generation computers with quite a few breakthroughs. It is based on the technique of Artificial Intelligence (AI). Computers can understand spoken words & imitate human reasoning.
Examples of first generation computers are ENIVAC and UNIVAC-1. They were based on vacuum tubes.
Pros
-Vacuum tubes were the only electronic component available during those days.
-Vacuum tube technology made possible to make electronic digital computers.
Cons
-The computers were very large in size.
-They consumed a large amount of energy.
-They were not very reliable.
Pros
-Smaller in size as compared to the first generation computers.
-The 2nd generation Computers were more reliable
cons
-Cooling system was required
-Constant maintenance was required
Pro
-Smaller in size as compared to previous generations.
-More reliable.
Con
- Air conditioning was required.
-Highly sophisticated technology required for the manufacturing of IC chips.

Pro
-More powerful and reliable than previous generations.
Small in size
-Fast processing power with less power consumption
Cons
-The latest technology is required for manufacturing of Microprocessors.
Pros
-Very fast and good
-good cooling system
Con
- Virus
-hacking computer
sixth generation
cube change to computer( easy to bring)
not require cooling system
no battery
cons
-need big space
