The clock speed of a computer is measured in Gigahertz (GHz). Clock speed refers to how fast a computer’s central processing unit (CPU) can process instructions. It is an important factor that determines the overall speed and performance of a computer.

One Gigahertz equals one billion cycles per second. This means that if a CPU has a clock speed of 3.0 GHz, it can perform 3 billion cycles every second. Each cycle represents an opportunity for the processor to fetch, decode, and execute instructions.

Gigahertz is the standard unit used for measuring the speed of modern CPUs. Higher clock speeds usually result in better performance, especially for tasks that require fast processing like gaming, video editing, and running heavy applications.
