Clock

nounStandard termElectronics

A continuous square wave signal that synchronizes the timing of digital circuits.

A clock provides the heartbeat for a digital system, oscillating between high and low logic states at a precise frequency. Flip-flops and microprocessors rely on its rising or falling edges to trigger state changes simultaneously across the board. Without a stable clock, data moving through sequential logic would quickly become corrupted by timing mismatches.

Heard on the job

The processor is halting because the clock is dropping cycles.
