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 becau se 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 co mpatible connection between two 
units. For example, the  computer’s internal display adapter receives 
information from the software and tr anslates it into images on the 
screen. An adapter can take a number of forms, from a 
microprocessor to a simple connect or. An intelligent adapter (one 
that is capable of doing some pr ocessing) may also be called a 
controller.
alternating current (AC)  — The type of power usually supplied to 
residential and commercial wall outle ts. 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 includ e 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/outpu t system (BIOS) — See BIOS. 
						

							
Glossary197
baud rate — The speed at which a comm unication 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 to check hardware and load  the operating system when you 
start up the computer.
bits per second (bps)  — A way of measuring the speed at which 
information is passed between two devices. This is the basic unit of 
measure used in modem communications, and 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 op erating 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 th e startup files. Under the default 
startup sequence, the computer lo oks for the startup files in the 
diskette drive before checking the hard disk.
bus  — An electrical circuit that c onnects 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 ce ntral processing unit (CPU) 
communicates with the othe r parts of the computer.
Ccache — A section of very fast memory in which frequently used 
information is duplicated for qu ick 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 opt ics instead of magnetic means for 
reading data. See also  CD. Compare  DVD-ROM. 
						

							
198Glossary
central processing unit (CPU) — The chip that functions as the “brain” 
of the computer. It takes informa tion 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-pro cessing program. A character 
occupies one byte of computer storage.
chip  — A small piece of silicon contai ning 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 pointing device’s primary button 
without moving the pointing device. In the Windows
® operating 
system, this refers to the pointing device’s left button, unless 
otherwise stated. See also  double-click.
color palette  — A set of specified colors th at establishes the colors that 
can be displayed on the scr een 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 compon ents 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 tran sfer 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 are using 
and what you are doing. 
						

							
Glossary199
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 dr ives, and modems are examples of 
devices.
device driver  — A program (called a “drive r”) 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.

influenced to hold information in digital form, and used in the 
production of magnetic disks, such as diskettes and hard disks. 
Compare  disc. See also  diskette, hard disk.
disk drive  — The device that reads and writes information and 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.
