MHz (MegaHertz)

Definition: One million cycles per second equals one megahertz. MHz is the unit used to measure the transmission speed of electronic devices, including networks. One-gigahertz means one billion times per second.

What This Means: The more MHz, the faster something exchanges information. As software applications get more complex and data grow, large increases in MHz are required to achieve even small, noticeable improvements in performance of computers and applications.
