Definition of "Clock" |
The basic timing signal in a digital system. / A device that generates periodic, accurately spaced signals used for timing applications. Related; Manufacturers of Integrated Circuit Timers, Manufacturers of Integrated Circuit Real Time Clocks. A reference source of timing information. A device providing signals used in a transmission system to control the timing of certain functions such as the duration of signal elements or the sampling rate. A signal waveform used to synchronize digital circuits. / In general, the clock refers to a microchip that regulates the timing and speed of all computer functions. Within this chip is a crystal that vibrates at a specific frequency when electricity is applied. The shortest time any computer is capable of performing is one clock, or one vibration of the clock chip. The speed of a computer processor is measured in clock speed, for example, 1 MHz is one million cycles, or vibrations, a second. 2GHz is two billion cycles, or vibrations, a second.A system clock or system timer is a continuous pulse that helps the computer clock keep the correct time. / (1) the oscillator circuit that generates a periodic synchronization signal. |
