286 Glossary
CLI
Abbreviation for command line interface.
CMOS
Acronym for complementary metal-oxide
semiconductor. In systems, CMOS memory chips are
often used for NVRAM storage.
command
The combination of an option and argument or just an
option if no argument is required, such as in the
following command line instances:
utilname --option
utilname --option=argument
command line example
A series of valid commands, options, and arguments
typed in the command line. For example, the
DTK utility name and all necessary options and
arguments as they are entered through the
operating system shell:
A:>utilname --option --option=argument
COMn
The device names for the first through fourth serial
ports on your system are COM1, COM2, COM3, and
COM4. The default interrupt for COM1 and COM3
is IRQ4, and the default interrupt for COM2 and
COM4 is IRQ3. Therefore, you must be careful when
configuring software that runs a serial device so that
you don't create an interrupt conflict.
config.sys file
The config.sys file is executed when you boot your
system (before running any commands in the
autoexec.bat file). This start-up file contains
commands that specify which devices to install and
which drivers to use. This file also contains commands
that determine how the operating system uses memory
and controls files.
ConsoleOne
Novell ConsoleOne is a Java-based foundation for
graphical utilities that manage and administer network
resources from different locations and platforms.
ConsoleOne provides a single point of control for all
Novell and external products.
console redirection
Console redirection is a function that directs a
managed system’s display screen, mouse functions, and
keyboard functions to the corresponding devices on a
management station. You may then use the management
station’s system console to control the managed system.
controller
A chip that controls the transfer of data between the
microprocessor and memory or between the
microprocessor and a peripheral device such as a disk
drive or the keyboard.
control panel
The part of the system that contains indicators and
controls, such as the power switch, hard drive access
indicator, and power indicator.
conventional memory
The first 640 KB of RAM. Conventional memory is
found in all systems. Unless they are specially designed,
MS-DOS
®
programs are limited to running in
conventional memory.
COO
Abbreviation for cost of ownership.
cooling unit
Sets of fans or other cooling devices in a system chassis.
coprocessor
A chip that relieves the system's microprocessor of
specific processing tasks. A math coprocessor, for
example, handles numeric processing. A graphics
coprocessor handles video rendering. The Intel
®
Pentium
®
microprocessor, for example, includes a
built-in math coprocessor.
