MegaHertz (MHz) is the name given to one million (106) Hertz, a measure of frequency. One MegaHertz simply means "one million per second" (1 000 000 / s). The unit may be applied to any periodic event – for example, a CPU clock might be said to operate at a rate expressed in MHz. Electromagnetic waves oscillate at rates which may be expressed in MHz. One million (1000000), one thousand thousand, is the natural number following 999999 and preceding 1000001. ... The hertz (symbol Hz) is the SI unit of frequency. ... Jump to: navigation, search Sine waves of various frequencies; the lower waves have higher frequencies than those above. ...

MegaHertz in radio

When used in the context of radio, MHz refers to the number of oscillations of electromagnetic waves per second. Several parts of the radio spectrum fall into the MHz range. Oscillation is the periodic variation, typically in time, of some measure as seen, for example, in a swinging pendulum. ... Electromagnetic radiation or EM radiation is a combination (cross product) of oscillating electric and magnetic fields perpendicular to each other, moving through space as a wave, effectively transporting energy and momentum. ...

MegaHertz in computing

Most CPUs are labelled in terms of their clock speed expressed in MegaHertz or GigaHertz (109 Hertz)). The number of MegaHertz refers to the frequency of the CPU's master clock signal ("clock speed"). Jump to: navigation, search This article needs to be cleaned up to conform to a higher standard of quality. ... In synchronous digital electronics, such as most computers, a clock signal is a signal used to coordinate the actions of two or more circuits. ...


Various computer busses, such as memory busses connecting the CPU and system RAM, also transfer data using clock signals operating at frequencies in the MegaHertz range. In computer architecture, a bus is a subsystem that transfers data or power between computer components inside a computer or between computers. ...
