Speak Like a Geek: The Complete Archive

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)  A display card standard that increases the speed at which display instructions travel from your system unit to the monitor. AGP is about four times faster than the previous standard display configuration.
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).
EDO (Extended Data Output)  A type of DRAM (dynamic RAM) memory that is faster than your average DRAM. Standard DRAM enables the CPU to read one byte of data at a time. EDO DRAM sticks a whole chunk of data in the cache and fetches another chunk while the CPU is reading the first chunk. SDRAM is better, so skip to that term.
EIDE (Enhanced Integrated Drive Electronics)  A type of hard drive that is typically fast and relatively inexpensive. EIDE drives have been popular for years but are being phased out by faster drives.
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.
EMS (Expanded Memory Specification)  See expanded memory.
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.
modem  An acronym for MOdulator/DEModulator. A modem is a piece of hardware that enables a computer to send and receive data through an ordinary telephone line.
monitor  A television-like screen on which the computer displays information.
motherboard  The big printed circuit board inside the system unit into which everything else plugs.
mouse  A hand-held device that you move across the desktop to move an arrow, called a mouse 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.
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 program that attaches itself to other files on a floppy or hard disk, 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.
