Technician A says that most vehicle microprocessors run on voltages higher than the usual 12-volt chassis voltage system.Technician B says that the rated processing frequency of a CPU is known as its clock speed.Who is correct?
A) Technician A only
B) Technician B only
C) Both A and B
D) Neither A nor B

Question

Quizplus · Accepted Answer

Technician B is correct because the rated processing frequency of a CPU is indeed referred to as its clock speed, which determines how many instructions per second the CPU can execute. Technician A is incorrect because most vehicle microprocessors are designed to operate at lower voltages, often 5 volts or 3.3 volts, to reduce power consumption and heat generation, not higher than the vehicle's 12-volt system.
