What was the base of first generation computer systems?

Correct option is B

First-generation computers were based on vacuum tube technology, which was used for processing and memory. These computers were large, power-hungry, and slow but marked the beginning of modern computing.

Important Key Points

• First-Generation Computers (1940s–1950s):
• Used vacuum tubes for circuitry and magnetic drums for memory.
• Required large space and generated excessive heat.
• Example: ENIAC, UNIVAC.
• Led to the development of transistors, which improved efficiency in later generations.

Knowledge Booster:

• Transistor based: Incorrect. Used in second-generation computers (1950s–1960s).
• Integrated Circuit based: Incorrect. Used in third-generation computers (1960s–1970s).
• VLSI microprocessor based: Incorrect. Used in fourth-generation computers (1970s–1980s and beyond).
