Answer:
Topic : Generations of Computer
Introduction:
The term Generation indicates the type of technologies are used in the computer construction, the new technologies improve the speed accuracy and storage capacity of computers.
S.No Name Generation & Description
1 First Generation 1946-1959 & Vacuum tube
2 Second Generation 1959-1965 & Transistor
3 Third Generation 1965-1971. Integrated Circuit
4 Fourth Generation 1971-1980 & VLSI
5 Fifth Generation 1980-till & ULSI
Advantages and Disadvantages:
1. First Generation:
Advantage - They were capable of making arithmetic and logical operations. They used the electronic values in place of the key punch machines or the unit record machines.
Disadvantage - Less operating capacity. High power consumption. Produce high temperature.
2. Second Generation:
Advantage - Low cost, better portability, better speed than first generation computers.
Disadvantage - A cooling system was required. Constant maintenance was required.
3. Third Generation:
Advantage - Fast and reliable. They used faster better device for storage.
Disadvantage - IC chips are difficult to maintain. Air conditioning is required.
4. Fourth Generation:
Advantage - Small in size, and very less cost. They were very compact faster.
Disadvantage - They are less powerful and had less speed than the main frame computers.
5. Fifth Generation: Advantage - They faster very cheap and have the highest possible storage capacity.
Disadvantage - They may make the human brains dull and doomed.
