Redundant Array of Inexpensive Disks. A method of spreading information across several disks set up to act as a unit, using two different techniques:
Disk striping: storing a bit of information across several discs (instead of storing it all on one disc and hoping that the disc doesn't crash).
Disk mirroring: simultaneously storing a copy of information on another disc so that the information can be recovered if the main disc crashes.
Random Access Memory. One of two basic types of memory. Portions of programs are stored in RAM when the program is launched so that the program will run faster. Though a PC has a fixed amount of RAM, only portions of it will be accessed by the computer at any given time. Also called memory.
Using the right mouse button to open context-sensitive drop-down menus.
Read-Only Memory. One of two basic types of memory. ROM contains only permanent information put there by the manufacturer. Information in ROM cannot be altered, nor can the memory be dynamically allocated by the computer or its operator.
