Correct option is B
The Second Generation of Computers (1956–1963) used transistors for the first time. Transistors replaced vacuum tubes, which were used in the First Generation of Computers. This change significantly improved computing performance, making computers smaller, faster, and more reliable.
Important Key Points:
- Second Generation Computers (1956–1963):
- Technology Used: Transistors replaced bulky vacuum tubes.
- Advantages of Transistors:
- Smaller size.
- Faster operation.
- Consumed less power.
- Generated less heat.
- Examples of Second Generation Computers:
- IBM 1401
- UNIVAC 1108
- CDC 1604
- Comparison with Other Generations:
- First Generation: Used vacuum tubes (slow, large, and unreliable).
- Second Generation: Used transistors (smaller, faster, and efficient).
- Third Generation: Used Integrated Circuits (ICs).
- Fourth Generation: Used Microprocessors.
Knowledge Booster:
- Why Not Other Options?
- a) Third Generation:
- Incorrect. The third generation used Integrated Circuits (ICs), not transistors.
- c) First Generation:
- Incorrect. The first generation used vacuum tubes for processing.
- d) Fourth Generation:
- Incorrect. The fourth generation introduced microprocessors (entire CPU on a chip).
- Advantages of Transistors:
- They were more reliable and efficient compared to vacuum tubes.
- They reduced the size and cost of computers.
- Interesting Fact:
- Transistors revolutionized computer technology and paved the way for the miniaturization of electronic devices, including modern computers and smartphones.
