system is ready for you to enter a command. You can enter an
operating system command or start a program from a system
prompt. To get to a system prompt from within Windows 95, quit

memory resident, that stays in memory even when you aren't
using it.
U
upper memory area (UMA): The area of memory between 640KB and
1MB. This area, used mostly for video memory and other system
functions, may also contain small blocks of unused memory

upper memory block (UMB): Continuous regions of the upper mem-
ory area into which the computer may load programs and device

utility: A computer program that lets you modify how certain aspects
of your computer work. Utilities differ from applications because
you don't use them to do real work—they just make your life eas-
ier. Different utilities manage your fonts, compress files and check
for viruses. MaxTime and Hardware Setup are examples of
utilities.
V
volatile memory: Random Access Memory (RAM) that is capable of
storing information only as long as the computer is powered on (or
in Resume Mode, until the battery discharges).
W
write protection: A safeguard that physically prevents you from delet-
ing the information on a diskette or other storage media. 5.25-inch
diskettes have a notch which must be covered to protect informa-
tion on the diskette. 3.5-inch diskettes have a small square hole
with a plastic tab. To protect information on the diskette, slide this
tab to uncover the hole.
