Q. Chief component of first generation computer was
- Transistors
- Vacuum Tubes and Valves
- Integrated Circuits
- None of above
Answer: Vacuum Tubes and Valves
Computer generations explain the history of computers based on evolving technologies. With each new generation, computer circuitry, size, and parts have been miniaturized, the processing and speed doubled, memory got larger, and usability and reliability improved.
The five generations of computers
Following are the main five generations of computers.
| S.No | Generation & Description |
|---|---|
| 1 | First Generation The period of the first generation: 1946-1959. Vacuum tube based. |
| 2 | Second Generation The period of the second generation: 1959-1965. Transistor-based. |
| 3 | Third Generation The period of the third generation: 1965-1971. Integrated Circuit based. |
| 4 | Fourth Generation The period of the fourth generation: 1971-1980. VLSI microprocessor based. |
| 5 | Fifth Generation The period of the fifth generation: 1980-onwards. ULSI microprocessor based. |
