What is hertz?
Hertz often abbreviated as Hz, is the standard unit of measurement that is used for measuring frequency. Because of the frequency being measured in cycles per second, one hertz is equal to one cycle per second. Frequently used for measuring the wave frequencies, like the sound waves, light waves and the radio waves. An average human ear can detect the sound wave that ranges from 20 to 20,000 Hz. Sound waves close that are close to 20 Hz which have a low pitch and are called ‘bass’ frequencies. Sound waves that go above 5000 Hz have a high pitch and are called ‘treble’ frequency. Hertz used for measuring wave frequencies, it also used to measure the speed of computer processors. To state an example, each CPU is rated at specific clock speed. The number is used to indicate how many instruction cycles the processor can perform each second. Modern processors can perform millions of even millions or even billions of instructions per second, clock speeds are often measured in megahertz or gigahertz.
