Answer:
Explanation:
Generation in computer terminology is a change in technology a computer is/was being used.
The period of second generation computers was 1959-1965. Transistors were used as an internal component. They averagely 10 times faster than the first generation computers. Main memory was in the form of RAM and ROM. Following are the main five generations of computers. The period of first generation: 1946-1959. Vacuum tube based. The period of second generation: 1959-1965.The second-generation computer is based on the transistor. The second-generation computer is costly.
FIRST GENERATION
1. Vacuum tubes were used as internal components.
2. The sizes of computer were very huge called mainframes.
3.They were low speed computer
4.Main memory was in the form of magnetic drum.
5.Punched card and magnetic tape was used.
SECOND GENERATION
1. Transistors were used as internal component.
2. The sizes of computer were smaller than first generation & were called as mini computer.
3. They were 10 times faster than first generation computer.
4. Main memory was in the form RAM and ROM.
5. Magnetic tape was used.
