The system clock or system timer,is dedicated to timing the activities on the motherboard much like a metronome helps a musician with timing. The chipset sends out a continuous pulsating electrical signal on one line of the system bus. This one system clock line, dedicated to carrying the pulse, is read by other components on the motherboard (including the processor, bus slots, memory slots, and so forth) and ensures that all activities are synchronized.
