Clock Speed

In a computer, clock speed refers to the number of pulses generated by an oscillator that sets the tempo for the processor. The faster the processor can access data, the faster the computer can perform its functions, given that other parts of the system are sufficiently tuned to support the particular clock speed.

Clock

In digital audio or video, a clock serves as a timing source. Data has to be executed at very specific times for digital audio or video to function properly. An issue that has to be addressed when synchronizing systems with each other. Although audio and video require different references to keep data passing through a system correctly, they both do it with the aid of a clock.
