R
radio frequency interference (RFI): All computer equipment generates
radio frequency signals. The FCC regulates the amount of RFI a
computing device can leak past its shielding. A Class A device is
sufficient for office use. Class B is a more stringent classification
applying to equipment for home use. Toshiba computers comply
with Class B computing device regulations.
radio frequency interference (RFI) shield: A metal shield enclosing the
printed circuit boards of the printer or computer to prevent
interference with radio and TV reception.
random access memory (RAM): High-speed memory which holds a
copy of the operating system, any currently executing application
programs, and any information undergoing processing. RAM is
volatile, which means that all information in RAM is lost when you
turn off the computer (unless Resume Mode is on or you have used
the Windows 95 or Windows NT Suspend feature).
read-only memory (ROM): A type of memory which the computer can
access but cannot change. It contains information that controls the
computer’s basic operation. ROM is non-volatile memory, which
means that the information stored in ROM is permanent—it is not
lost when you turn off the computer.
reboot: See boot , restart .
Registry: The central information database for Windows 95/98 or
Windows NT. It holds hardware specific information and stores
configuration details for programs, reducing the need for
initialization (.INI) files.
remapping: Redefining a computer component. For example, remapping
the keyboard refers to assigning a new symbol or letter for some or
all of the keys.
removable disk: (also called floppy disk) A thin, flexible disk in a
protective jacket that stores magnetically encoded data. Disks can
be removed from the computer and come in two sizes: 5.25-inch
and 3.5-inch. Your computer uses 3.5-inch disks.
