Hertz & Seconds:
A hertz is one cycle per second.
Megahertz (MHz):
Megahertz (MHz) equals to one million cycles of the system clock.
(Mega is a prefix that stands for million. A computer that operates at 933 MHz has 933 million clock cycles in one second.)
Gigahertz (GHz):
Gigahertz (GHz) equals to one billion cycles of the system clock. In relation with megahertz, 1.0GHz is equivalent to 1000 MHz.
Giga is a prefix that stands for billion. GHz is most often used as a measurement of a PC processor chip and power, with bigger numbers meaning more speed and higher price. A microprocessor that runs at 200 GHz executes 200 billion cycles per second. For a 2.4 GHz machine, its clock rate is 2.4 billion cycles per second.
