Answer:
system clock.
Step-by-step explanation:
A computer can be defined as an electronic device that is capable of receiving of data in its raw form as input and processes these data into information that could be used by an end user.
The central processing unit (CPU) is typically considered to be the brain of a computer system. It is the system unit where all of the processing and logical control of a computer system takes place.
Additionally, the component of the central processing unit (CPU) that controls the overall operation of a computer is the control unit. It comprises of circuitry that makes use of electrical signals to direct the operations of all parts of the computer system. Also, it instructs the input and output device (I/O devices) and the arithmetic logic unit on how to respond to informations sent to the processor.
The processor's system clock controls the timing of all the computer operations.
This ultimately implies that, the central processing unit (CPU) of a computer depends or relies on the system clock which is typically designed to control the timing of all the operations performed by a computer.
Basically, the system clock is a small quartz crystal circuit and it measures the timing of a computer with respect to its operations.
