Explain about  clock rate ?

CLOCK RATE--

• the clock rate or clock speed typically refers to the frequency at which the clock generator of a processor can generate pulses, which are used to synchronize the operations of its components, and is used as an indicator of the processor's speed.
• It is measured in clock cycles per second or its equivalent, the SI unit hertz (Hz).
• The clock rate of the first generation of computers was measured in hertz or kilohertz (kHz)
