Pronounced pee-ram, short for parameter RAM. On Macintosh computers, PRAM is a small portion of RAM used to store information about the way the system is configured. For example, parameter RAM holds the date and time, desktop pattern, mouse settings, volume settings, and other control data set with control panels. Parameter RAM is powered by a battery, so it does not lose its contents when the power is turned off.
