Select the correct option from the following:
| (a) | (b) | (c) | (d) | |
| (1) | (iii) | (iv) | (i) | (ii) |
| (2) | (iii) | (i) | (iv) | (ii) |
| (3) | (iii) | (i) | (ii) | (iv) |
| (4) | (i) | (iii) | (iv) | (ii) |
- Option : B
- Explanation : A vacuum tube computer, now termed a first- generation computer, is a computer which uses vacuum tubes for logic circuitry. A second generation computer which is also called transistor computer is a computer which uses discrete transistors instead of vacuum tubes. The computers of third generation used Integrated Circuits (ICs) in place of transistors. A single IC has many transistors, resistors, and capacitors along with the associated circuitry. The period of fourth generation was from 1971-1980. Computers of fourth generation used Very Large Scale Integrated (VLSI) circuits. VLSI circuits have about 5000 transistors.
