MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -one instruction per clock pulse. pulses to execute a single instruction. execution of one instruction per clock cycle, even with the faster clock.

Detailed explanation-2: -Techopedia Explains Clock Cycle Early computer processors and CPUs used to execute one instruction per clock cycle. However, with advances in microprocessor technology, modern microprocessors such as superscalar are capable of executing multiple instructions per clock cycle.

Detailed explanation-3: -The IF, ID and WB stages take one clock cycle each to complete the operation.

Detailed explanation-4: -The clock speed measures the number of cycles your CPU executes per second, measured in GHz (gigahertz). In this case, a “cycle” is the basic unit that measures a CPU’s speed. During each cycle, billions of transistors within the processor open and close .

Detailed explanation-5: -Without pipelining, in a multi-cycle processor, a new instruction is fetched in stage 1 only after the previous instruction finishes at stage 5, therefore the number of clock cycles it takes to execute an instruction is five (CPI = 5 > 1).
