MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Your CPU processes many instructions from different programs every second. Some of these instructions involve simple arithmetic, while others are more complicated. The clock speed measures the number of cycles your CPU executes per second, measured in GHz (gigahertz).

Detailed explanation-2: -CPU Performance. Elapsed time and throughput are two different ways of measuring speed. Elapsed time is the better measure for processor speed because it is less dependent on other system components. When processor performance is quantified, it is taken to be inversely proportional to execution time.

Detailed explanation-3: -the correct answer is GigaHertz. Clock speed: Clock speed is the significant way to measure the performance of Processor.

Detailed explanation-4: -CPU efficiency is a measure of how well an application utilizes its requests for CPU. Efficiency is calculated with the following formula: efficiency=cpu time / (run time x number of cpus).

Detailed explanation-5: -Million instructions per second (MIPS) is a measure of a processor’s speed, providing a standard for representing the number of instructions that a central processing unit (CPU) can process in 1 second.
