Aloha~! My name is Zalgo and I am here to help you out on this amazing day. The answer you are looking for is "In a computer system, the clock speed refers to the number of pulses per second generated by an 'oscillator' that will set the tempo for the processor. Clock speed is usually measured in MHz (MHz stands for megahertz, or millions of pulses per second) or GHz (gigahertz, or billions of pulses per second).
I hope that this answer helped you! :D
