FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The clock speed of computers is usually measured in megahertz (MHz) or gigahertz (GHz). One megahertz equals one million ticks per second, and one gigahertz equals one billion ticks per second. You can use clock speed as a rough measurement of how fast a computer is.

Detailed explanation-2: -The clock speed measures the number of cycles your CPU executes per second, measured in GHz (gigahertz).

Detailed explanation-3: -Console systems like the Xbox and PlayStation generally do not exceed 60 frames per second and 60 Hz. For computers and laptops we recommend 144 Hz. You should try to have the same or more Hz than frames per second when gaming. 3D content requires 120 Hz.

Detailed explanation-4: -Because the clocks they use to mediate their activities are electronic and they vibrate at a given frequency to generate their signals. So it makes sense to express their rate of vibration in hertz in terms of cycles per second similar to radio frequencies.

Detailed explanation-5: -Hertz is widely used to refer to the clock rate of a CPU; for example, 2 GHz means two billion cycles per second. The term is also used for other repeating cycles such as frame rate; for example, a 60 Hz TV displays 60 frames per second.
