Question 4

Transistors are characteristic of second-generation computing.

Second-generation computing is defined by the use of transistors, which replaced vacuum tubes and allowed for more reliable, efficient, and compact computers.

A) Artificial intelligence

While artificial intelligence is a significant advancement in computing, it is not characteristic of second-generation computing. AI emerged later, primarily associated with third-generation and beyond, where systems became capable of more complex problem-solving and learning.

B) Nanotechnology

Nanotechnology is a modern field that manipulates matter at the atomic or molecular scale. It is not specific to any generation of computing and does not define second-generation computing, which is fundamentally tied to the use of transistors for processing.

C) Transistors

Transistors are the hallmark of second-generation computing, marking a shift from the bulky and inefficient vacuum tubes used in first-generation computers. Transistors enabled smaller, faster, and more energy-efficient machines, which is a key characteristic of this generation.

D) Microprocessors

Microprocessors are a feature of third-generation computing, which built upon the foundation laid by second-generation technologies. While they represent a significant advancement over transistors, they do not define the second generation itself.

Conclusion

Transistors are undeniably the defining technology of second-generation computing, facilitating the transition to smaller and more efficient computers. The other options either pertain to later advancements in computing or do not relate directly to the characteristics of the second generation, making them incorrect in this context.
