COMPUTER FUNDAMENTALS

Detailed explanation-1: -In order to synchronize all of a computer’s operations, a system clock-a small quartz crystal located on the motherboard-is used. The system clock sends out a signal on a regular basis to all other computer components.

Detailed explanation-2: -A system clock or system timer is a continuous pulse that helps the computer clock keep the correct time. It keeps count of the number of seconds elapsed since the epoch, and uses that data to calculate the current date and time.

Detailed explanation-3: -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.
