The computer world is like a big exclusive club, complete
with its own language. If you want to be accepted into the Royal Order of
Computer Geeks, you had better learn the lingo. The following mini glossary
helps you start.
ActiveX A
relatively new technology that makes it easy both to embed animated objects,
data, and computer code in the documents that you create and to share those
objects with others. For example, with ActiveX, you can open a file created in
Microsoft Word in your Web browser (for instance, Internet Explorer) and edit
it just as if you had opened it in Word.
AGP (Accelerated Graphics Port
Application Also
known as program, a set of instructions that enable a computer to
perform a specific task, such as word processing or data management. An
application can also be a collection of programs, called a suite.
ASCII file A
file containing characters that any program on any computer can use. Sometimes
called a text file or an ASCII text file. (ASCII is pronounced
"ASK-key.")
BIOS (basic input-output system) The BIOS, pronounced "BUY-ose," is
the built-in set of instructions that tell the computer how to control the disk
drives, keyboard, printer port, and other components that make up your
computer. Think of the BIOS as the little black box inside new cars that keeps
everything working in sync. The BIOS is stored on a ROM (read-only
memory) chip. A flash BIOS enables you to update the BIOS by running a
software program instead of replacing the ROM chip. A PnP BIOS supports
plug-and-play components.
bit The
basic unit of data in a computer. A computer's alphabet consists of two
characters--
1 and 0. 1 stands for On, and 0 stands for Off. Bits are combined in sets of
eight to form real characters, such as A, B, C, and D.
See also byte.
bits per second A
unit for measuring the speed of data transmission. Remember that it takes 8
bits to make a byte (the equivalent of a single character). Modems have common
bps ratings of 28,800 to 56,600.
boot To
start a computer and load its operating system software (usually Windows).
bps See
bits per second.
bus A
superhighway that carries information electronically from one part of the
computer to another. The wider and faster (speed is measured in MHz) the bus,
the faster your computer. The old ISA bus could carry 16 bits of data at a
time; the newer PCI bus can carry 32 bits or 64 bits. There are three such
highways:
- A data bus
carries data back and forth between memory and the microprocessor.
- An address bus
carries information about the locations (addresses) of specific
information.
- A control bus
carries control signals to make sure that the data traffic flows smoothly,
without confusion.
byte A
group of 8 bits that usually represents a character or a digit. For example,
the byte 01000001 represents the letter A.
cache Pronounced
"cash." A temporary storage area in memory or on disk that computer
components and various programs use to quickly access data.
CD-ROM (compact disc-read-only memory) A storage technology that uses the same kind of
discs that you play in an audio CD player for mass storage of computer data. A
single disc can store more than 600MB of information. Pronounced
"see-dee-rahm."
cell The
box formed by the intersection of a row (1,2,3...) and column (A,B,C...) in a
spreadsheet. Each cell has an address (such as B12) that defines its
column and row. A cell may contain text, a numeric value, or a formula.
chat To
talk to another person by typing at your computer. What you type appears on the
other person's screen, and what the other person types appears on your screen.
You can chat on the Internet or an online service, such as Prodigy or America
Online.
click To
move the mouse pointer over an object or icon and press and release the mouse
button once without moving the mouse.
client Of
two computers, the computer that's being served. On the Internet or on a
network, your computer is the client, and the computer to which you're
connected is the server.
Clipboard A
temporary storage area that holds text and graphics. The Cut and Copy commands
put text or graphics on the Clipboard, replacing the Clipboard's previous
contents. The Paste command copies Clipboard data to a document.
CMOS (Complementary Metal-Oxide Semiconductor) Pronounced "sea-moss," this is a
battery-powered storage unit that helps your computer remember the date, time,
and additional settings. If your computer starts losing track of time, it might
be a sign that you need to change the battery.
COM port Short
for COMmunications port. A receptacle, usually at the back of the computer,
into which you can plug a serial device such as a modem, mouse, or serial
printer. If your computer has more than one COM port, the ports are numbered
COM1, COM2, and so on.
command An
order that tells the computer what to do. In command-driven programs, you have
to press a specific key or type the command to execute it. With menu-driven
programs, you select the command from a menu.
computer Any
machine that accepts input (from IVuser), processes the input, and produces
output in some form.
CPU (central processing unit) The computer's brain. See microprocessor.
crash Failure
of a system or program. Usually, you realize that your system has crashed when
you can't move the mouse pointer or type anything. The term crash is
also used to refer to a disk crash (or head crash). A disk crash
occurs when the read/write head in the disk drive falls on the disk. This would
be like dropping a phonograph needle on a record. A disk crash can destroy any
data stored where the read/write head falls on the disk.
cursor A
horizontal line that appears below characters. A cursor acts like the tip of
your pencil; anything that you type appears at the cursor. See also insertion
point.
data The
facts and figures that you enter into the computer and that are stored and used
by the computer.
database A
type of computer program used for storing, organizing, and retrieving
information. Popular database programs include Access, Approach, and Paradox.
density A
measure of the amount of data that can be stored per square inch of storage
area on a disk.
desktop publishing (DTP) A
program that enables you to combine text and graphics on the same page and
manipulate the text and graphics onscreen. Desktop publishing programs are
commonly used to create newsletters, brochures, flyers, résumés, and business
cards.
dialog box An
onscreen box that enables you to enter your preferences or supply additional
information. You use the dialog box to carry on a "conversation" with
the program.
directory A
division of a disk or CD, which contains a group of related files. Think of
your disk as a filing cabinet, and think of each directory as a drawer in the
cabinet. By keeping files in separate directories, it is easier to locate and
work with related files. Directories are more commonly called folders.
disk A
round, flat, magnetic storage medium. A disk works like a cassette tape,
storing files permanently so that you can play them back later. See also floppy
disk and hard disk.
disk drive A
device that writes data to a magnetic disk and reads data from the disk. Think
of a disk drive as a cassette recorder/player. Just as the cassette player can
record sounds on a magnetic cassette tape and play back those sounds, a disk
drive can record data on a magnetic disk and play back that data.
docking station A
unit that connects a portable computer to peripherals, making the portable
computer act like a desktop computer. Docking stations typically enable you to
connect a mouse, full-size keyboard and monitor, speakers, and a printer to
your notebook computer.
DOS (disk operating system) DOS, which rhymes with "boss," is an
essential program that provides the necessary instructions for the computer's
parts (keyboard, disk drive, central processing unit, display screen, printer,
and so on) to function as a unit. Although Windows makes DOS nearly obsolete,
you still see its name floating around in Windows.
DOS prompt An
onscreen prompt that indicates that DOS is ready to accept a command but
provides no clue as to what command you should type. It looks something like
C> or C:\.
download To
copy files from another computer to your computer, usually through a modem. See
also upload.
DVD (digital versatile disk or digital video disk) Disks that can store more than seven times as
much data as a CD, making them useful for storing full-length movies. DVD
drives are designed to handle the discs of the future but are also designed to
play discs of the past (CDs).
EIDE (Enhanced
Integrated Drive
email Short
for electronic mail, email is a system that enables people to send and
receive messages from computer to computer. Email is usually available on
networks and online information services.
executable file A
program file that can run the program. Executable files end in .BAT, .COM, or
.EXE.
expanded memory Additional memory that a computer uses by swapping data
into and out of a reserved portion of a computer's standard memory area. With
expanded memory, additional memory is added to the computer in the form of
memory chips or a memory board. To access this additional memory, an expanded
memory manager reserves 64 of the standard 640KB as a swap area. The 64KB
represent four pages, each page consisting of 16KB. Pages of data are swapped
into and out of this 64KB region from expanded memory at a high speed. Old DOS
programs commonly used expanded memory, but Windows and its programs prefer
extended memory. See also extended memory.
expansion slot An
opening on the motherboard (inside the system unit) that enables you to add
devices to the system unit. Expansion slots enable you to add an internal
modem, sound card, video accelerator, or other enhancement.
extended memory Any
memory above the standard 640KB that performs the same way as the standard
memory. Extended memory is directly available to the processor in your
computer, unlike expanded memory, in which data must be swapped into and
out of the standard memory. Most of your computer's memory is extended memory.
extension The
portion of a file's name that comes after the period. Every filename consists
of two parts--the base name (before the period) and an extension (after the
period). The filename can be up to eight characters in DOS and Windows 3.x (up
to 255 characters in Windows 95 and later). The extension (which is optional)
can be up to three characters.
FAT32 A
fairly recent hard disk innovation that divides large hard disk drives into
small storage units so that the drive wastes less space. If you think of your
hard disk as a parking lot, Fat32 paints the lines closer together so that it
can fit more cars. See also file allocation table.
field A
blank in a database record, into which you can enter a piece of information
(for example, a telephone number, ZIP code, or a person's last name).
file A
collection of information stored as a single unit on a floppy or hard disk.
Files always have a filename to identify them.
file allocation table (FAT) A map on every disk that tells the operating
system where the files on the disk are stored. It's a little like a classroom
seating chart for files.
File Transfer Protocol (FTP) A set of rules that govern the exchange of
files between two computers on the Internet. To copy a file from the Internet,
you need a special program that can handle FTP file transfers.
fixed disk drive A
disk drive that has a nonremovable disk, as opposed to floppy drives, in which
you can insert and remove disks.
floppy disk A
wafer encased in plastic that stores magnetic data (the facts and figures you
enter and save). Floppy disks are the disks that you insert in your computer's
floppy disk drive (located on the front of the computer).
folder The
Windows name for a directory, a division of a hard disk or CD-ROM that stores a
group of related files. See also directory.
font Any
set of characters of the same typeface (design) and type size
(measured in points). For example, Times Roman 12-point is a font: Times Roman
is the typeface, and 12-point is the size. (There are 72 points in an inch.)
format (disk) To
prepare a disk for storing data. Formatting creates a map on the disk that
tells the operating system how the disk is structured. The operating system
uses this map to keep track of where files are stored. Formatting also flags
bad tracks or sectors (storage areas) on the disk, to prevent the drive from
attempting to store data on defective areas.
format (document) To
establish the physical layout of a document, including page size, margins,
running heads, line spacing, text alignment, graphics placement, and so on.
FTP See File
Transfer Protocol.
function keys The
10 or 12 F keys on the left side of the keyboard or 12 F keys at the top of the
keyboard (some keyboards have both). F keys are numbered F1, F2, F3, and so on,
and you can use them to enter specified commands in a program.
geek 1. An
obsessive computer user who sacrifices food, sleep, and other pleasantries of
life to spend more time at the keyboard. 2. A carnival performer whose act
usually includes biting off the head of a live snake or chicken.
gigabyte A
thousand megabytes. See megabyte.
graphical user interface (GUI, pronounced
"GOO-ey") A type of
program interface that uses graphical elements, such as icons, to represent
commands, files, and (in some cases) other programs. The most famous GUI is
Microsoft Windows.
hard disk A
disk drive that comes complete with a nonremovable disk. It acts as a giant
floppy disk drive and usually sits inside your computer.
Hayes-compatible A
term to describe a modem that uses the Hayes command set for communicating with
other modems over the phone lines. Hayes-compatible modems usually are
preferred over other modems because most modems and telecommunications software
are designed to be Hayes-compatible.
HTML Short
for Hypertext Markup Language, the code used to create documents for the
World Wide Web. These codes tell the Web browser how to display the text
(titles, headings, lists, and so on), insert anchors that link this document to
other documents, and control character formatting (by making it bold or
italic).
icon A
graphic image onscreen that represents another object, such as a file on a
disk.
infrared A
type of port, normally found on notebooks, which enables cable-free
connections. You can then set your notebook in front of your printer (if the
printer has an infrared port, too) and print, or connect your notebook to your
desktop PC or network without a cable. Infrared ports work like TV and VCR
remote controls, and you have to point one infrared device right at the other
one to get it to work.
insertion point A
blinking vertical line used in most Windows word processors to indicate the
place where any characters that you type are inserted. An insertion point is
the equivalent of a cursor.
integrated program A
program that combines the features of several programs, such as a word
processor, spreadsheet, database, and communications program.
interactive A
user-controlled program, document, or game. Interactive programs commonly
display onscreen prompts asking the user for input so that they can
decide how to carry out a particular task. These programs are popular in
education, enabling children to follow their natural curiosity to solve
problems and gather information.
interface A
link between two objects, such as a computer and a modem. The link between a
computer and a person is called a user interface and refers to the way a
person communicates with the computer.
Internet A
group of computers all over the world that are connected to each other. Using
your computer and a modem, you can connect to these other computers and tap
their resources. You can view pictures, listen to sounds, watch video clips,
play games, chat with other people, and even shop.
IRC Short
for Internet relay chat, this is the most popular way to chat with others on
the Internet. With an IRC client (chat program), you connect to an IRC server,
where you are presented with a list of available chat rooms. You can enter a
room and then start exchanging messages with others in the room.
ISDN (Integrated
Services Digital Network) ISDN is a system that enables your
computer, using a special ISDN modem, to perform digital data transfers over
special phone lines. Non-ISDN modems use analog signals, which are designed to
carry voices, not data. ISDN connections can transfer data at a rate of up to
128Kbs, compared to about 56Kbps for the fastest analog modems.
keyboard The
main input device for most computers. You use the keyboard to type and to enter
commands.
kilobyte (KB) A
unit for measuring the amount of data. A kilobyte is equivalent to 1,024 bytes
(each byte is a character).
laptop A
small computer that's light enough to carry. Notebook computers and
subnote-books are even lighter.
load To
read data or program instructions from disk and place them in the computer's
memory, where the computer can use the data or instructions. You usually load a
program before you use it or load a file before you edit it.
macro A
recorded set of instructions for a frequently used or complex task. In most programs,
you create a macro by telling the program to record your actions. You then name
the macro or assign to it a keystroke combination. You can replay the macro at
any time by selecting its name or by pressing the keystroke combination that
you assigned to it.
megabyte A
standard unit used to measure the storage capacity of a disk and the amount of
computer memory. A megabyte is 1,048,576 bytes (1,000KB). This is roughly
equivalent to 500 pages of double-spaced text. Megabyte is commonly abbreviated
as M, MB, or Mbyte.
memory An
electronic storage area inside the computer, used to temporarily store data or
program instructions when the computer is using them. The computer's memory is
erased when the power to the computer is turned off. Also referred to as RAM.
menu A list
of commands or instructions displayed onscreen. Menus organize commands and
make a program easier to use.
MHz (megahertz) Pronounced
"mega-hurts," the unit used to measure the speed at which computer
parts work. For example, a Pentium II 300MHz processor is faster than a Pentium
II 233MHz processor. You should, however, compare speeds only between
comparable devices. For example, if one device transmits 32 bits of data per
clock cycle at 75MHz, and another device transmits only 16 bits of data per
clock cycle at 150MHz, the second device isn't any faster overall.
microprocessor Sometimes
called the central processing unit (CPU) or processor, this chip is the
computer's brain; it does all the calculations for the computer.
MMX This
acronym doesn't stand for anything. MMX is a new multimedia technology,
developed by Intel, that enables your computer's CPU (processor) to take on
more of the workload for handling multimedia files. This enables your computer
to play media files faster and more smoothly.

pointer, across the screen. Used instead of the keyboard to select and move
items (such as text or graphics), execute commands, and perform other tasks.
MS-DOS (Microsoft disk operating system) See DOS.
multitasking The
process of performing two computer tasks at the same time. For example, you can
be printing a document from your word processor while checking your email in
Prodigy. One of the primary advantages of Windows is that it enables you to
multitask.
network computer A
network computer (or NC) is a streamlined version of a standard PC, which
relies on a network server or on Internet servers for most of its computing
power. A typical network computer has a monitor, keyboard, mouse, processor,
and memory but no hard drive or CD-ROM drive. Programs are stored on a central
network computer. Although NCs cannot replace PCs, NCs are excellent for
corporations because they require little maintenance and support.
newsgroup An
Internet bulletin board for users who share common interests. There are
thousands of newsgroups, ranging from body art to pets (to body art with pets).
Newsgroups let you post messages and read messages from other users.
notebook A
portable computer that weighs between 4 and 8 pounds.
online Connected,
turned on, and ready to accept information. Used most often in reference to a
printer or modem.
pane A
portion of a window. Most programs display panes, so you can view two different
parts of a document at the same time.
parallel port A
connector used to plug a device, usually a printer, into the computer.
Transferring data through a parallel port is much faster than through a serial
port, but parallel cables can carry data reliably only 15 to 20 feet.
partition A
section of a disk drive that's assigned a letter. A hard disk drive can be
divided (or partitioned) into one or more drives, which your computer
refers to as drive C, drive D, drive E, and so on. The actual hard disk drive
is called the physical drive, and each partition is called a logical
drive; however, these terms don't matter much--the drives still look like
letters to you.
patch A set
of program instructions designed to fix a programming bug or add capabilities
to a program. On the Internet, you can often download patches for programs to
update the program.
path The
route that the computer travels from the root directory to any subdirectories
when locating a file.
PC card An
expansion card that's about the size of a credit card, though thicker, and
slides into a slot on the side of the notebook computer. PC cards enable you to
quickly install RAM or a hard disk drive, modem, CD-ROM drive, network card, or
game port, without having to open the notebook computer. See also PCMCIA.
PCI (Peripheral Component Interconnect) A bus standard that effectively doubles
or quadruples the amount of data that can travel around the highway system inside
your computer. See also bus.
PCMCIA (Personal Computer Memory Card International
Association) An organization
that has set standards for notebook computer expansion cards. See also PC
card.
Pentium The
most popular CPU for PCs is manufactured by Intel. During the writing of this
book, the Pentium II was the latest, greatest chip, offering speedy performance
and support of MMX technology. You may also encounter an older Pentium, called
Pentium (the original), Pentium Pro (a step up from the Pentium), or Pentium
MMX (Pentium with enhanced multimedia features). A Pentium II is essentially a
Pentium Pro with built-in MMX support.
peripheral A
device that's attached to the computer but is not essential for the basic
operation of the computer. The system unit is the central part of the computer.
Any devices attached to the system unit are considered peripheral,
including a printer, modem, or joystick. Some manufacturers consider the
monitor and keyboard to be peripheral, too.
pixel A dot
of light that appears on the computer screen. A collection of pixels forms
characters and images on the screen.
PnP Short
for plug-and-play, PnP enables you to install expansion cards in your computer
without having to set special switches. You plug it in, and it works.
port replicator A
slimmed down version of a docking station. See also docking station.
ports The
receptacles at the back of the computer. They get their name from the ports
where ships pick up and deliver cargo. In this case, the ports enable
information to enter and leave the system unit.
PPP (Point-to-Point Protocol) A language that computers use to talk to one
another. What's important is that when you choose an Internet service provider,
you get the right connection--SLIP or PPP.
program A
group of instructions that tells the computer what to do. Typical programs are
word processors, spreadsheets, databases, and games.
prompt A
computer's way of asking for more information. The computer basically looks at
you and says, "Tell me something." In other words, the computer is prompting
you or prodding you for information or a command.
protocol A
group of communications settings that control the transfer of data between two
computers.
pull-down menu A
menu that appears at the top of the screen, listing various options. The menu
is not visible until you select it from the menu bar. The menu then drops down,
covering a small part of the screen.
random-access memory (RAM) Where your computer stores data and programs
temporarily. RAM is measured in kilobytes and megabytes. In general, more RAM
means that you can run more powerful programs and more programs at once. Also
called memory.
record Used
by databases to denote a unit of related information contained in one or more
fields, such as an individual's name, address, and phone number.
ROM BIOS See
BIOS.
scanner A
device that converts images, such as photographs or printed text, into an
electronic format that a computer can use. Many stores use a special type of
scanner to read bar code labels into the cash register.
Screen Tip See
ToolTip.
scroll To
move text up and down or right and left on a computer screen.
SCSI (Small Computer System Interface) Pronounced "scuzzy," SCSI provides
speedier data transfer rates than are available through standard serial or
parallel ports and enables you to connect several devices to the same port.
Although SCSI makes it much easier to add SCSI compatible devices to your
computer, USB offers greater flexibility.
SDRAM (synchronous dynamic RAM) A type of RAM (memory) that is twice as fast as
EDO DRAM because it synchronizes itself with the CPU. Although fast (operating
at speeds of 100MHz), SDRAM has trouble keeping up with newer processors, which
run at speeds of 300MHz. Look for even faster memory chips, such as RDRAM and SLDRAM.
server Of
two computers, the computer that's serving the other computer. On the Internet
or on a network, your computer is the client, and the computer to which
you're connected is the server.
service provider The
company that you pay in order to connect to its computer and get on the
Internet.
shareware Computer
programs that you can initially use for free and then must pay for if you
decide to continue using them. Many programmers start marketing their programs
as shareware, relying on the honesty and goodwill of computer users for their
income. That's why most of these programmers have day jobs.
software Any
instructions that tell your computer (the hardware) what to do. There are two
types of software: operating system software and application software. Operating
system software (such as Windows) gets your computer up and running. Application
software enables you to do something useful, such as type a letter or chase
lemmings.
spreadsheet A
program used for keeping schedules and calculating numeric results. Common
spreadsheets include Lotus 1-2-3 ,
Microsoft Excel, and Quattro Pro.
status bar The
area at the bottom of a program window that shows you what's going on as you
work. A status bar may show the page and line number where the insertion point
is positioned and indicate whether you are typing in overstrike or insert mode.
style A
collection of specifications for formatting text. A style may include
information for the font, size, style, margins, and spacing. Applying a style
to text automatically formats the text according to the style's specifications.
taskbar A
fancy name for the button bar at the bottom of the Windows desktop.
TCP/IP (Transmission Control Protocol/Internet Protocol) A set of rules that govern the transfer of data
over the Internet. To do anything on the Internet, you need a TCP/IP program.
This program connects your computer to your service provider's computer, which
is part of the Internet. You can then run other programs that enable you to do
fun stuff such as browse the World Wide Web. Windows Dial-Up Networking is the
only TCP/IP program that you need.
TFT (thin film transistor) A technology used to improve the resolution on
flat-panel displays, like those used on notebook computers.
toolbar A
strip of buttons typically displayed near the top of a program window, below
the menu bar. The toolbar contains buttons that you can click to enter common
commands, enabling you to bypass the menu system.
ToolTip A
small text box that displays the name of a button when you rest the mouse
pointer on the button. ToolTips help you figure out what a button does, when
you cannot figure it out from the picture.
touchpad A
pointing device commonly found on laptop computers that enables you to move the
mouse pointer by running your finger over the pad.
trackball A
device, often used with laptop computers, which works like an upside-down
mouse. It requires less desk space than a mouse because instead of moving it
around the desk to move the pointer onscreen, you roll it in place to move the
pointer.
transfer rate A
measure of how much information a device (usually a disk drive) can transfer
from the disk to your computer's memory in a second. A good transfer rate is in
the range of 500 to 600KB per second. The higher the number, the faster the
drive.
uninterruptible power supply (UPS) A battery-powered device that protects against
power spikes and power outages. If the power goes out, the UPS continues
supplying power to the computer so that you can continue working or can safely
turn off your computer without losing data.
upload To
send data to another computer, usually through a modem and a telephone line or
through a network connection.
URL (uniform resource locator) An address for an Internet site. The Web uses
URLs to specify the addresses of the various servers on the Internet and the
documents on each server. For example, the URL for the Whitehouse server is http://www.whitehouse.gov.
The http stands for Hypertext Transfer Protocol, which means this is a
Web document; www stands for World Wide Web; whitehouse stands
for Whitehouse; and gov stands for government.
USB (Universal Serial Bus) The ultimate in plug-and-play technology. USB
enables you to install devices without turning off your computer or using a
screwdriver. You plug the component into the USB port, and it works. USB
enables you to connect up to 127 devices to a single port. You can daisy-chain
the devices with cables up to 5 meters long. Daisy-chain means that you
can plug one device into the system unit, another device into the first device,
and so on, until you have completely filled your office with add-ons.
Usenet (User's
Network) A collection of computers that is responsible for
managing the flow of messages posted in newsgroups. See also newsgroup.
virtual memory Disk
storage that is treated as RAM (memory). Windows 95 can use disk space as
virtual memory.
virus A

duplicates itself without the user's knowledge, and may cause the computer to
do strange and sometimes destructive things. The virus attacks the computer by
erasing files from the hard disk or by formatting the disk.
Web See World
Wide Web.
Web browser A
program that enables you to navigate the World Wide Web (the most popular
feature of the Internet). The World Wide Web consists of documents (pages) that
may contain text, graphics, sound clips, video clips, and other items. A Web
browser pulls the pages into your computer (using a modem or network
connection) and displays them on your screen. See also World Wide Web.
wild card Any
character that takes the place of another character or a group of characters.
In DOS, you can use two wild card characters: a question mark (?) and an
asterisk (*). The question mark stands in for a single character. The asterisk
stands in for a group of characters.
Windows A
way of displaying information in different parts of the screen. Often used as a
nickname for Microsoft Windows.
word processor A
program that enables you to enter, edit, format, and print text.
word wrap A
feature that automatically moves a word to the next line if the word won't fit
at the end of the current line.
World Wide Web A
part of the Internet that consists of multimedia documents that are
interconnected by links. To move from one document to another, you click a
link, which may appear as highlighted text or as a small picture or icon. The
Web contains text, sound, and video clips, pictures, catalogues, and much, much
more. See also Web browser.
write-protect To
prevent a computer from adding or modifying data stored on a disk.
