What is defined as a clock cycle?

• A. A single calculation done by the CPU
• B. The time taken for a signal to complete one full oscillation
• C. An action initiated by sending voltage to the clock wire
• D. The time taken for the CPU to process a command

Answer: (C)

A clock cycle refers to the fundamental unit of time in which a CPU operates, allowing it to synchronize actions within the computer. The clock signal generates a regular pulse that dictates when the CPU can read and write data. It’s during each clock cycle that the CPU can perform operations such as executing an instruction, accessing memory, or communicating with other components. Choosing the option that states "an action initiated by sending voltage to the clock wire" captures this definition well, as it highlights the role of the clock signal in coordinating the timing of these operations. The clock generates a series of electrical pulses that effectively act as the clock ticks, marking the start and end of each operation cycle in the CPU. Understanding this concept is crucial, as it establishes the rhythmic basis upon which all processes within a CPU are timed, enabling it to function efficiently and predictably.
