Detailed explanation-1: -The speed at which a microprocessor can execute the instructions is called the clock speed. Basically clock speed is the number of cycles that the processor executes per second. We measure it in MHz(MegaHertz) or GHz (Giga Hertz). Here, MHz means 1 million cycles per second and GHz means 1 billion cycles per second.
Detailed explanation-2: -A CPU’s clock speed represents how many cycles per second it can execute. Clock speed is also referred to as clock rate, PC frequency and CPU frequency. This is measured in gigahertz, which refers to billions of pulses per second and is abbreviated as GHz.
Detailed explanation-3: -The speed at which the CPU can carry out instructions is called the clock speed. This is controlled by a clock. With every tick of the clock, the CPU fetches and executes one instruction. The clock speed is measured in cycles per second, and one cycle per second is known as 1 hertz.
