Megahertz (MHz) is a unit of measurement for frequency, representing one million cycles per second. It is commonly used to measure the speed of electronic devices, such as computer processors and radio frequencies. For example, a 2 MHz processor completes two million cycles of operations per second, while a radio signal operating at 100 MHz means the signal's frequency is 100 million cycles per second. Megahertz is commonly used in radio, television, and wireless communication to describe the frequency at which signals are transmitted.
