Question

The time required for the fetching and execution of one simple machine instruction is?

• A. Delay time
• B. CPU cycle
• C. Real time
• D. Seek time
• E. None of the above

Answer 1

The correct option is B CPU cycle

The time required for the fetching and execution of one simple machine instruction is CPU cycle

The speed of a computer processor, or CPU, is determined by the clock cycle, which is the amount of time between two pulses of an oscillator. Generally speaking, the higher number of pulses per second, the faster the computer processor will be able to process information.

cycles per instruction (aka clock cycles per instruction, clocks per instruction, or CPI) is one aspect of a processor's performance: the average number of clock cycles per instruction for a program or program fragment. It is the multiplicative inverse of instructions per cycle.
