Question 1

Which electronic component was primarily used in first-generation computers?

Accepted Answer

Vacuum Tubes. Vacuum tubes were the core switching technology for first-generation computers. These machines were very large in size and consumed a lot of electricity. ENIAC and UNIVAC are famous examples of this era.

Question 2

The transition from vacuum tubes to which component marked the start of the second generation?

Accepted Answer

Transistors. Transistors replaced vacuum tubes because they were smaller, faster, and more reliable. This change allowed computers to become more compact and energy-efficient. Magnetic core memory was also introduced during this period.

Question 3

What major technological advancement defined third-generation computers?

Accepted Answer

Integrated Circuits. Integrated Circuits (ICs) combined many transistors onto a single silicon chip. This invention significantly increased the speed and efficiency of computer systems. The IBM 360 series is a prominent example of this generation.

Question 4

Which generation of computers introduced the use of microprocessors with VLSI technology?

Accepted Answer

Fourth Generation. Fourth-generation computers utilized Very Large Scale Integration (VLSI) to put thousands of components on one chip. This led to the development of Personal Computers (PCs) we use today. This era saw the rise of graphical user interfaces and the mouse.

Question 5

Fifth-generation computers are characterized by which emerging technology?

Accepted Answer

Parallel Processing and AI. Fifth-generation systems focus on Artificial Intelligence and Ultra Large Scale Integration (ULSI). These computers aim to process natural language and exhibit human-like reasoning. Voice recognition and quantum computing are key research areas in this phase.
