Computers can only do one thing at a time.
A CPU processes digital data by taking data one piece at a time. The amount of time it takes to process anything is decided by a quartz clock.
With every tick of the clock, the CPU is able to process one piece of data or execute one instruction.
The CPU clock speed is measured in cycles, 1 cycle per second is also known as 1 hertz.
A computer running on 1GHz can carry out a thousand million instructions per second.
The speed of the clock determines the basic preformance of the CPU.
