Detailed explanation-1: -A system clock controls the timing of all operations performed in the fetch-execute cycle. It does so by generating regular electronic pulses or ticks, that set the operating pace of components of the system unit. Every operation in the processor: data movement, computations etc; takes place during a clock pulse.
Detailed explanation-2: -. The processor’s execution is governed by an external clock. This clock, the system clock, generates regular clock pulses to the processor and, each clock pulse, the processor does some work. For example, a processor could execute an instruction ever clock pulse.
Detailed explanation-3: -The unit of measurement called a hertz (Hz), which is technically one cycle per second, is used to measure clock speed. In the case of computer clock speed, one hertz equals one tick per second. The clock speed of computers is usually measured in megahertz (MHz) or gigahertz (GHz).
Detailed explanation-4: -Each central processing unit (CPU) produces a series of electronic pulses at a predetermined rate, called the clock speed, which affects machine cycle time.
Detailed explanation-5: -One gigahertz (GHz) equals one billion ticks of the system clock per second.
