RAM
Random Access Memory. The portion of the computer's
memory used to run programs and store data while you work.
All data stored in RAM is erased when you turn off or reset the
computer; so you must store any data you want to keep on a
storage device.
The frequency with which a monitor can redraw a screen
image. The faster the refresh rate, the less the screen will flicker.
Read Only Memory. A portion of memory that can only be
read and cannot be modified. ROM uses power from a backup
battery to retain its contents when you turn off the computer.
RS-232C
A widely used, standard type of serial communication. You can
connect up to two RS-232C devices to the computer's built-in
serial ports.
SCI files

the EISA Configuration utility that contain all the information
about the option cards you have installed and how all of your
system resources are allocated. The most current SCI file is
called SYSTEM.SCI.
