Answer:
FIRST GENERATION
advantage It made use of vacuum tubes which are the only electronic component available during those days.
These computers could calculate in milliseconds.
disadvantages. These were very big in size, weight was about 30 tones.
These computers were based on vacuum tubes.
These computers were very costly.
It could store only a small amount of information due to the presence of magnetic drums.
As the invention of first generation computers involves vacuum tubes, so another disadvantage of these computers was, vacuum tubes require a large cooling system.
Very less work efficiency.
Limited programming capabilities and punch cards were used to take inputs.
Large amount of energy consumption.
Not reliable and constant maintenance is required.
SECOND GENERATION
advantages. Due to the presence of transistors instead of vacuum tubes, the size of electron component decreased. This resulted in reducing the size of a computer as compared to first generation computers.
Less energy and not produce as much heat as the first genration.
Assembly language and punch cards were used for input.
Low cost than first generation computers.
Better speed, calculate data in microseconds.
Better portability as compared to first generation
disadvantages. A cooling system was required.
Constant maintenance was required.
Only used for specific purposes
THIRD GENERATION
advantages. These computers were cheaper as compared to second-generation computers.
They were fast and reliable.
Use of IC in the computer provides the small size of the computer.
IC not only reduce the size of the computer but it also improves the performance of the computer as compared to previous computers.
This generation of computers has big storage capacity.
Instead of punch cards, mouse and keyboard are used for input.
They used an operating system for better resource management and used the concept of time-sharing and multiple programming.
These computers reduce the computational time from microseconds to nanoseconds
disadvantages IC chips are difficult to maintain.
The highly sophisticated technology required for the manufacturing of IC chips.
Air conditioning is required
