Solutions: Megahertz: Megahertz is a unit of measurement for indicating the frequency of one million electrical vibration cycles per second. It is a unit to measure oscillation frequency of the computer's internal timing clock. A 12-megahertz computer uses an internal electronic clock that pulses twelve million times a second. The pulse sets the tempo at which the microprocessor and other components operate. One Hertz (Hz) is equal to one cycle per second. Heinrich R. Hertz, a German physicist, first detected electromagnetic waves in 1883. The original IBM-Personal Computers in the early 1980's were controlled by Central Processing Units (CPU's) that were synchronized with clock crystals vibrating at 4.77 megahertz. The bandwidth of your computer monitor is measured in MHz.
