Show answer & explanation
Correct answer: C
CONCEPT
A computer generation is identified by the dominant hardware technology used to build its central processing circuitry.
Moving backward from the fourth generation to the first therefore retraces the increasing levels of component integration in reverse chronological order.
APPLICATION
Fourth generation: Microprocessors placed the central processing unit on a single integrated chip.
Third generation: Integrated circuits combined many electronic components on semiconductor chips.
Second generation: Transistors replaced bulky vacuum tubes as switching devices.
First generation: Vacuum tubes formed the main electronic switching and amplification technology.
CROSS-CHECK AND CONTRAST
Reading the sequence forward from the first generation to the fourth gives Vacuum Tubes → Transistors → Integrated Circuits → Microprocessors.
Integrated Circuits → Microprocessors → Transistors → Vacuum Tubes reverses the fourth- and third-generation technologies.
Microprocessors → Integrated Circuits → Vacuum Tubes → Transistors reverses the first- and second-generation technologies at the end.
Transistors → Vacuum Tubes → Microprocessors → Integrated Circuits begins with a second-generation technology instead of the fourth-generation technology.
Thus, from the fourth generation to the first, the answer by value is Microprocessors → Integrated Circuits → Transistors → Vacuum Tubes.
