What is MHz (megahertz)?

Megahertz is a unit of alternating current (AC) or electromagnetic (EM) wave recurrence equivalent to 1,000,000 hertz. The megahertz is usually utilized to communicate microprocessor clock speed means Hertz (Hz) is one cycle per second. MHz is a typical proportion of the transmission speed of electronic devices, for example, computer buses, RAM and CPUs. One MHz is equivalent to one million (1,000,000) Hz. The most widely recognized utilization for hertz is to depict radio and sound frequencies.
