When used in the context of radio, MHz refers to the number of oscillations of electromagnetic radiation. Severel parts of the radio spectrum fall into the MHz range:
The HF, VHF, UHF references are something of a misnomer: most radiocommunications today occur at higher frequencies due to congestion in the lower frequency bands. Experts in the field of radiocommunications classify these other categories of spectrum by bands. The names of these bands are idosyncratic, but are used often in radiocommunications.
A common alternative means of describing a radio frequency is using its wavelength, though since the adoption of the hertz as an SI unit, this is becoming rare. Wavelength varies inversely to frequency, i.e., high frequencies are associated with short wavelengths.
Most CPUThe central processing unit (CPU is the part of a computer that interprets and carries out the instructions contained in the software. In most CPUs, this task is divided between a control unit that directs program flow and one or more execution units thats made between 19741974 is a common year starting on Tuesday (click on link for calendar).

Events Y2K passes without the seri were labelled in terms of megahertz (though modern computers have processor speeds in the gigahertz (109 hertz) range). The number of megahertz refers to the frequency of the CPU's master clock signalIn synchronous digital electronics, such as most computers, a clock signal is a signal used to coordinate the actions of two or more circuits. A clock signal oscillates between a high and a low state, normally with a 50% duty cycle. In other words, the si.
It is often assumed that if two CPUs have different "clock speeds", the one with the higher clock speed will be faster than the other. However, while clock speed is an important factor in overall performance, many other factors influence the performance of computers, and a better comparison is archived by using benchmarkA benchmark is a point of reference for a measurement. The term presumably originates from the practice of making dimensional height measurements of an object on a workbench using a graduated scale or similar tool, and using the surface of the workbench as.

Computer architecture In Computer architecture, an instruction is a single operats that can be accomplished quickly, may run at a higher clock rate (at higher MHz) than a CISC processor with complex instructions. But because the CISC processor accomplishes more during each clock, it may be faster for any real-world application.
