Processor speed: The operations of the ALU and control unit are performed at incredible speed. These operations are usually synchronized by a built-in electronic clock {known as system clock}, which emits millions of regularly space electric pulsar per second (known as digital cycles clock), commands are interpreted, and then executed at proper intervals, and the intervals are timed by a specific number of clock cycles. One cycle is the time it takes to perform one operation. such as moving it byte of data from one the memory location to another normally several clo

ck cycles are required to fetch decode and execute a (single program) instruction. The shorter the clock cycle and faster the processor, Hence, the speed with which an instruction is executed is directly related to the computer’s built-in clock speed, which is the number of pulses, produced per second. Over the years clock speeds of processors have increased steadily. Most of today’s popular personal computers have clock speeds in the 500-to2000-MHz range. However, Processors are now being built with even faster rating with all other parameters being equal (although they never) are a CPU. Operating at 500 MHz can process data, five times as fast as one operating at 100 MHz.
