Kellakiirusest, also known as clock speed or clock rate, refers to the speed at which a central processing unit (CPU) or other digital circuits can execute instructions. It is typically measured in Hertz (Hz), with common units being Megahertz (MHz) and Gigahertz (GHz). One Hertz represents one cycle per second. A higher clock speed generally indicates that the processor can perform more operations in a given amount of time, leading to faster overall performance for computational tasks.

The clock speed is determined by an internal oscillator within the processor that generates a series of regular electrical pulses, or clock cycles. Each cycle allows the processor to perform a basic operation, such as fetching data, decoding instructions, or performing arithmetic calculations. The number of cycles a processor can complete per second directly correlates to how quickly it can process information.

However, clock speed is not the sole determinant of a processor's performance. Other factors such as the number of cores, cache size, architecture efficiency, and the speed of the system bus also play significant roles. A processor with a lower clock speed but a more efficient architecture or more cores might outperform a processor with a higher clock speed but fewer cores or a less efficient design. Therefore, while clock speed is an important metric, it should be considered alongside other specifications when evaluating processor performance.
