or clock speed, representing a cycle of time. An
oscillator circuit supplies a small amount of
electricity to a crystal each second that is
measured in MHz or GHz, where "Hz" is the
abbreviation of Hertz, "M" representing Mega, or one
million, and "G" representing Giga, or one thousand
million. In addition to GHz and MHz, there is KHz,
or 1,000 Hz. |
