Also referred to as clock rate, clock
speed is that speed the microprocessor executes each instruction. The CPU
requires a number of cycles to execute an instruction. Thus, the faster the
clock speed, the faster the CPU and the faster it can execute instructions in a
second.
In computer science, an instruction is an order or operation given to a processor by software (computer program). A group of instructions is called a field. Fields of instructions are first stored in the memory of the processor and then executed by the microprocessor. The microprocessor's clock speed is the speed at which it executes instructions.
