Clock Cycle
/ˈklɒk ˈsaɪkəl/
noun — "the fundamental timing interval of a synchronous system."
A Clock Cycle is the smallest repeating unit of time that governs operation in a synchronous digital system. It is defined by a clock signal, typically a periodic electrical waveform, that coordinates when components are allowed to change state. Each clock cycle represents one complete period of this signal, and it serves as the heartbeat that synchronizes computation, data movement, and control throughout a system.
