A computer’s megahertz (MHz) is a measure of how fast and efficiently the computer’s processor can perform. In layman terms, it is one million cycles or revolutions per second. In most cases, the higher the MHz, the more work the computer can get done in a certain amount of time (though speed still varies depending on the computer processor). So MHz is a simple measure of speed. Keep in mind that while many computers will show MHz, some, more modern systems will show GHz (gigahertz)—one GHz is equivalent to 1000 MHz.
