A phase locked loop or PLL is a circuit in which both the frequency and phase of a variable frequency oscillator is locked to a reference frequency or to a frequency with a simple numerical relationship to it. The many applications include digital tuning in a radio and the generation of the different clock frequencies for the processor and RAM in a computer.
