Evolution Of Computers Questions & Answers

Question 4: Explain the difference between the first generation and second generation of computers?


  • The first generation of computers used vacuum tubes as the main electronic component. They were very large in size and expensive.
  • The second generation of computers replaced vacuum tubes with transistors. Because of the transistors the size of the second-generation computers reduced to a large extent.

Question 5: List any three advantages of computers.


  • Speed – Computers can process complex operations within seconds. 
  • Reliability – They are very reliable; they rarely break or fail.
  • Consistency – If we enter the same input and processes, a computer will produce the same results each time.

Question 6: Write a short note on fifth generation computers.


  • This generation uses the ULSI (Ultra Large Scale Integration) technology which makes it possible to produce microprocessor chips having millions of circuit elements on a single chip.
  • The fifth generation computers are also using AI (Artificial Intelligence) technology
  • The aim of Fifth generation is to develop computer-based devices that can respond to natural language input and that are capable of self-learning and self-decision making.
  • Examples: powerful desktops, laptops, tablets, notebook and smart phones.

Question 7: What is the advantage of Artificial Intelligence? Explain with example.


  • A computer can be made to think like a human being with the help of AI.
  • For example – ASIMO has the ability to recognize moving objects, postures, gestures, its surrounding environment, sounds, and faces, which enables it to interact with humans.

Question 8: What are the features of a supercomputer?


  • Supercomputers are the most powerful computers in terms of performance, data processing and speed.
  • They are very expensive and quite large.
  • A supercomputer needs to be accommodated in large air-conditioned rooms; some super computers can span an entire building.
  • These are specialised and task-specific computers used by very large organisations.

Question 9: Computers are being used in many different fields. However, they still cannot replace human beings. Justify.

Answer: A computer cannot replace a human being. It cannot think more than what it is programmed for and cannot take a decision in a particular situation on its own. Human beings can perceive a change in a situation and take a different approach based on their experience and wisdom.

Question 10: List some disadvantages of computers.

Answer: Some disadvantages of computers are:

i. Impact on the labor force 

Computer based machines can do multiple tasks. Hence, reducing the number of laborers. This increases unemployment.

ii. Privacy 

Personal and confidential records if not protected properly may get violated and identities may get stolen.

iii. Health risks

This occurs with prolonged and improper use of a computer.

iv, Impact on environment

Computer manufacturing processes are depleting natural resources and polluting the environment. Computer waste or e-waste is a major concern today.
