Show answer & explanation
Correct answer: C
Concept
A computer generation is identified by the dominant electronic switching technology used to build its processing circuits.
The standard progression is from discrete vacuum-tube devices to transistors, then to integrated circuits, and finally to microprocessors that place the CPU on a chip.
Application
B denotes vacuum tubes, the defining technology of first-generation computers.
D denotes transistors, which define the second generation.
C denotes integrated circuits, which define the third generation.
A denotes microprocessors, which define the fourth generation.
Cross-check
The technological scale moves from individual vacuum-tube components to discrete semiconductor devices, to many components integrated on a chip, and then to a complete processor on a chip. This independently gives the same sequence.
Therefore, the required order is B, D, C, A.
