The following terms may appear in this user’s guide.
Aactive-matrix display — A liquid crystal display (LCD) made 
from an array of liquid crystal cells using active-matrix 
technology. Also known as a “TFT display,” in its simplest form 
there is one thin film transistor (TFT) for each cell. This type of 
display works well with notebook computers because of its 
shallow depth and high-quality color. Active-matrix displays are 
viewable from wider angles than most passive-matrix displays.
adapter — A device that provides a compatible connection 
between two units. For example, the computer’s internal display 
adapter receives information from the software and translates it 
into images on the screen. An adapter can take a number of 
forms, from a microprocessor to a simple connector. An 
intelligent adapter (one that is capable of doing some processing) 
may also be called a controller.

alternating current (AC) — The type of power usually supplied to 
residential and commercial wall outlets. AC reverses its direction 
at regular intervals. Compare direct current (DC).
application — A computer program that you use to perform tasks 
of a specific type. Applications include word processors, 
spreadsheets, and database management systems. See also 
program.
Bbackup — A copy of a file, usually on a removable disk, kept in 
case the original file is lost or damaged.
basic input/output system (BIOS) — See BIOS.
baud rate — The speed at which a communication device, such as 
a printer or modem, transmits information. Baud rate is the 
number of signal changes per second (not necessarily the same as 
bits per second). See also bits per second.
BIOS (basic input/output system) — Basic instructions, stored in 
read-only memory (ROM), containing the information the 
computer needs in order to check hardware and load the 
operating system when you start up the computer.
bit: — Short for “binary digit.” A bit is the smallest unit of 
information used by a computer. A group of eight bits is a byte. 
See also byte.
bits per second (bps) — A way of measuring the speed at which 
information is passed between two devices. The basic measure 
used in modem communications, bps is similar, but not identical, 
to the baud rate. See also baud rate.
boot — To start the computer. The term “boot” originates from 
bootstrap program (as in “pulling itself up by its bootstraps”), a 
program that loads and initializes the operating system. See also 
reboot.
boot disk — See system disk.
boot priority (startup sequence) — The order in which the 
computer accesses its disk drives to locate the startup files. Under 
the default startup sequence, the computer looks for the startup 
files in the diskette drive before checking the hard disk.

bus — An electrical circuit that connects the central processing unit 
(CPU) with other parts of the computer, such as the video 
adapter, disk drives, and ports. It is the pathway through which 
data flows from one device to another. See also bus speed, 
frontside bus.
bus speed — The speed at which the central processing unit (CPU) 
communicates with the other parts of the computer.
byte — A sequence of eight bits. A byte is the smallest addressable 
unit of data. See also bit, gigabyte, kilobyte, megabyte.
Ccache — A section of very fast memory in which frequently used 
information is duplicated for quick access. Accessing data from 
cache is faster than accessing it from the computer’s main 
memory. See also CPU cache, L1 cache, L2 cache.
CD — An individual compact disc. See also CD-ROM.
CD-ROM (compact disc read-only memory) — A form of high-
capacity storage that uses laser optics instead of magnetic means 
for reading data. See also CD. Compare DVD-ROM.
central processing unit (CPU) — The chip that functions as the 
“brain” of the computer. It takes information from outside 
sources, such as memory or keyboard input, processes the 
information, and sends the results to another device that uses the 
information.
character — Any letter, number, or symbol you can use on the 
computer. Some characters are non-printing characters, such as a 
paragraph break in a word-processing program. A character 
occupies one byte of computer storage.
chip — A small piece of silicon containing computer logic and 
circuits for processing, memory, input/output, and/or control 
functions. Chips are mounted on printed circuit boards.
click — To press and release the TouchPad control button or mouse 
button without moving the cursor or mouse. In the Windows
® 
operating system, this refers to the left mouse button or primary 
TouchPad control button, unless otherwise stated. See also 
double-click.

color palette — A set of specified colors that establishes the colors 
that can be displayed on the screen at a particular time.
compatibility — The extent to which computers, programs, or 
devices can work together harmoniously, using the same 
commands, formats, or language as another.
configuration — (1) The collection of components that make up a 
single computer system. (2) How parts of the system are set up 
(that is, configured).
controller — A device that controls the transfer of data from a 
computer to a peripheral device and vice versa. For example, disk 
drives, monitors, keyboards, and printers all require controllers.
CPU — See central processing unit (CPU).
CPU cache — A section of very fast memory residing between the 
CPU and the computer’s main memory that temporarily stores 
data and instructions the CPU will need to execute commands 
and programs. See also cache, L1 cache, L2 cache.
cursor — A symbol that indicates the current position on the 
screen. The shape of the cursor varies, depending on the program 
you’re using and what you’re doing.
Ddefault — The setting selected by a program when the user does 
not specify an alternative setting.
device — A component attached to the computer. Devices may be 
external (outside the computer’s case) or internal (inside the 
computer’s case). Printers, disk drives, and modems are examples 
of devices.
device driver — A program (called a “driver”) that permits a 
computer to communicate with a device.
dialog box — An on-screen window displayed by the operating 
system or a program giving a direction or requesting input from 
the user.
direct current (DC) — The type of power usually supplied by 
batteries. DC flows in one direction. Compare alternating current 
(AC).

the CPU, that enables direct data transfer between memory and a 
device.
directory — See folder.

disc — A round, flat piece of metal, designed to be read from and 
written to by optical (laser) technology, and used in the 
production of optical discs, such as CDs and DVDs. Compare

influenced to hold information in digital form, and used in the 
production of magnetic disks, such as diskettes and hard disks.

programs on a diskette or hard disk. It rotates the disk at high 
speed past one or more read/write heads.
diskette — A thin, flexible disk in a protective jacket that stores 
magnetically encoded data. Diskettes can be removed from the 
computer and come in two sizes: 5.25-inch and 3.5-inch. Your 
computer uses 3.5-inch diskettes. See also double-density 
diskette, high-density diskette.
document — Any file created with an application and, if saved to 
disk, given a name by which it can be retrieved. See also file.
