`

`Although this book covers nearly every aspect of
`computing, it does not include entries on most com-
`panies or on most makes and models of computers,
`nor does it contain entries on most application soft-
`ware products. The few exceptions to this role of
`thumb are key companies and products that have a
`historical or universal importance within the com-
`puting industry.
`This dictionary emphasizes tem~inology that the
`average computer user will encounter in documen-
`tation, online help, computer manuals, marketing
`and sales materials, the popular media, and the
`computer trade press. Because most computer
`users operate personal computers and desktop sys-
`tems at home, work, or both, the majority of the
`entries in this dictionary cover the terminology
`used in describing and working with these systems.
`However, some specialized or highly technical lan-
`guage is included that pertains to areas of industry,
`academia, software and hardware development,
`and research. These terms have been included be-
`cause they have a bearing on more common com-
`puter terminology or because they are of historical
`significance.
`
`Changes in the Third Edition
`
`The third edition of the Microsoft Press Com-
`puter Dictionary has been revised and updated
`to reflect the many advances in the computer
`field and to include several areas that have
`come into prominence in the public eye, such
`as the Internet. Over 2,500 new eI~tries have been
`added, covering the Internet, the World Wide
`Web, network computing, hardware and software
`advances, virtual reality, multimedia, and work-
`group computing.
`Existing entries from the second edition of the
`Microsoft Press Computer Dictiomary have been
`updated to include changes in the field.
`All entries have been styled in a more traditional
`dictionary forr~at than in previous editions. Pronun-
`ciations and parts of speech are given for all terms.
`Entries that have more than one sense, or definition,
`are broken into numbered lists.
`
`Order of Presentation
`
`Entries are alphabetized by letter. Spaces are
`ignored, as are characters such as hyphens and
`slashes; for example, Baudot code falls between
`baud and baud rate, and machine-independent
`falls between machine identification and machine
`instruction. Numbers and symbols are located at the
`beginning of the book and are listed in ascending
`ASCII order. If an entry begins with a letter or letters
`but contains a number, it is listed alphabetically,
`according to the initial letter(s), and then according
`to ASCII order. Thus, V20 precedes V.2x, and both
`precede VAB.
`
`Entries
`
`Entries are of two types: main entries, which contain
`full definitions, and synonymous cross-references,
`which contain See references to the appropriate
`main entries. Synonymous cross-references are gen-
`erally secondary or less common ways of referring
`to a main entry. The definition at the main entry can
`be substituted as a definition for the synonymous
`cross-reference.
`
`Format
`
`Information in each main entry is presented in a con-
`sistent format: entry name in boldface, spelling vari-
`ants (if any), pronunciation, part of speech,
`definition, illustration or table references (if any),
`acronym (if any), alternative names (if any), and
`cross-references (if any).
`
`Main Entries
`
`Entries that are acronyms or abbreviations for one
`or more words or concatenations of two or more
`words have those words spelled out at the begin-
`ning of the definition. The letters in these words or
`phrases that make tip the acronym, abbreviation, or
`concatenation are in boldface.
`When a main entry is spelled exactly the same as
`another main entry, the two entries are differenti-
`ated by the use of a superscript numeral after each
`
`Petitioner Microsoft Corporation and HP Inc. - Ex. 1030, p. vi
`
`

`

`term. These entries are called homographs, and they
`are generally different parts of speech. For example,
`
`e_mailI (noun)
`e-mail2 (verb)
`
`Spelling Variants
`
`When a main entry has one or more variations in the
`way it is spelled, each spelling variant follows the
`main entry, after the word or.
`
`Pronunciations
`Pronunciation keys appear after all defined terms in
`the dictionary. Within the pronunciation keys, indi-
`vidual words are separated by word spaces, and syl-
`lables within each word are separated by stress
`marks or hyphens.
`
`Variant Pronunciations
`The Microsoft Press ComPuter Dictionary, Third Edi-
`tion uses a generalized system for representing pro-
`nunciations, particularly for the vowels. There are
`many subtle variations, well known to phonologists
`in particular, in the ways Americans in different
`parts of the United States pronounce many vowels.
`However, most can recognize words that are pro-
`nounced slightly differently by others and should be
`able to interpret the broad category represented for
`each of the vowel sounds in this dictionary and
`apply it in their own regional variation or dialect.
`This dictionary represents only standard American
`pronunciations, but there are cases in which suffi-
`cient divergence in pronunciation exists, even
`within the United States, so some variant pronunci-
`ations have been included.
`Variants are separated by commas, and the most
`common pronunciation may appear first. However,
`because there are many cases where two pronunci-
`ations are (at least roughly) equally widely used, the
`order in which they appear shotild not be inter-
`preted to mean that the first one given is more "cor-
`rect" or common than the other(s). Variants are
`shown on a word-by-word basis; for a multiword
`entry, pronunciation keys are given only for the
`word or words that have variant pronunciations.
`
`For words that are spelled with the letters wh,
`the pronunciation is listed with two variants: one
`with a simple w (w) and one with the hw sound
`(hw).
`Words that are spelled with either au or aw
`include a variant pronunciation with the letter o
`with a circumflex accent (6), which represents the
`vowel sound some Americans (those who make a
`significant distinction between this sound and a
`"regular" short o) pronounce when they say the
`word dawn. In some parts of the country, this
`vowel sound is also used in words with other spell-
`ings, such as coffee or talk, but this seems to be a
`distinctly dialectical variation rather than a standard
`one. It is therefore very difficult for any individual
`to predict how any other might pronounce these
`particular words, so variants have not been included
`for them.
`
`Stress
`The syllable or syllables pronounced with the heavi-
`est, or primary, stress in a term are followed by
`acute accents (’); those with lighter, or secondary,
`stress are followed by grave accents (’). For exam-
`ple, in the word computer, the second syllable is
`spoken more forcefully, or with more stress, than
`the first and third syllables and therefore is followed
`in the pronunciation key by an acute accent (kam-
`py~’tar). In the word engineering, the third syllable
`is stressed most heavily, but the first syllable is
`stressed more than the second or fourth, so the first
`syllable is followed by a grave accent, indicating
`secondary stress (en’ja-n~r’~ng).
`
`Special Characters and Diacritics
`
`The dictionary’s pronunciation schema keeps the
`use of technical phonetic characters to a minimum.
`Instead, a system that is more familiar to most
`Americans represents short vowels with plain letters
`(a, e, i, o, u) and long vowels with overbars (~,
`6, ~). The ligatured o’s represent the vowel sounds
`in the words foot (o~) and food
`The letter a with an umlaut (~t) is included as
`an alternative to the short o (o). It is used when
`the vowel is represented orthographically by some
`
`vii
`
`Petitioner Microsoft Corporation and HP Inc. - Ex. 1030, p. vii
`
`

`

`sent foreign sounds as they are pronounced in their
`original language; only Americanized pronuncia-
`tions are given for foreign words and names.
`
`IPA
`
`a ~e
`e
`
`letter or combination of letters other than the letter
`o, such as a (as in father), au (as in caught), or
`aw (as in dawn). This is done mainly to avoid
`confusing the reader visually with pronunciations
`such as won’dar for the word wander.
`One other pair of alternative characters is used to MPCD
`represent a single vowel sound: the schwa (;D) and
`a short u (u). Traditionally, the schwa has been
`reserved for unstressed, or reduced, vowels, but in
`recent years it has become much more commonly
`used in dictionaries to also represent the short,
`stressed u. In this dictionary, the short u is used
`only in words that are spelled with the letter u, and
`the schwa is used for all other spellings except for
`"syllabic l’s," in which cases the vowel is dropped
`entirely, as in the word little (li’tl).
`One other diacritic used in the pronunciations is
`a circumflex over the letter a (5_). This is used
`instead of the short e only in combination with the
`letter r, to represent the vowel sound heard in
`words such as air, software, and very. This is done
`to avoid representations such as ker~ak-t;Dr for the
`word character, which might lead some readers to
`believe that the sound should be pronounced as is
`the er in the word her.

`When acronyms ale pronounced as a series of

`sent the pronunciation of the letters; for example,
`the pronunciation for the term EPS is E’P-S’, not
`~’p~-es’. Note.. Letter-by-letter pronunciations are
`included for all acronyms in the dictionary, even
`those that are pronounced as words by most peo-
`ple; for example, the pronunciation for the term
`ASCII includes both a’sk~ and A" S-C-I-I ~.

`Parts of Speech
`Entries are broken down into four parts of speech,
`in addition to prefixes, abbreviated as follows:
`
`noun
`n.
`verb
`vb.
`adj.
`adjective
`adv. adverb
`
`Definitions
`Each of the more than 7,300 entries is written in
`clear, standard English. Many go beyond a simple
`definition to provide additional detail and to put the
`term in context for a typical computer User. When
`an entry has more than one sense or definition, the
`definitions are presented in a numbered list, to
`make it easier to distinguish the particular, some-
`times subtle, variations in meaning.
`
`Illustration and Table References
`
`Some entries have affiliated illustrations or tables
`that aid in defining the entry. In most cases, illustra-
`tions and tables appear on the same page as the
`entries to which they apply. In some instances,
`however, page layout requirements have forced
`them to a subsequent page. Entries with illustrations
`or tables usually have references at the end of the
`definition for an entry, in the following formats:
`
`See the illustration.
`See the table.
`
`Acronyms
`Some terminology in the computer field, particu-
`larly computer standards and Internet slang, can
`be shortened to form acronyms. Sometimes the
`acronym is the more common way to refer to the
`concept or object; in these cases, the acronym is
`the main entry. In other cases, the acronym is not
`as commonly used as the words or phrase for
`which it stands. In these cases, the words or phrase
`constitute the main entry. The acronym is given
`after the definition for these entries in the follow-
`ing format:
`
`Acronym..
`
`Alternative Names
`Some items or concepts in the computer field can be
`referred to by more than one name. Generally,
`though, one way is preferred. The preferred termi-
`nology is the main entry. Alternative names are
`listed after any acronyms; otherwise they are listed
`after the definition in the following format:
`
`Also called.,
`
`Cross-References
`Cross-references are of three types: See, See also,
`and Compare. A See reference is used in an entry
`that is a synonymous cross-reference and simply
`points to another entry that contains the information
`sought. A See also reference points to one or more
`entries that contain additional or supplemental
`information about a topic and follows any acronyms
`or alternative names after the definition. A Compare
`reference points to an entry or entries that offer con-
`trast and follows any See also references; otherwise
`it follows any acronyms or alternative names after
`the definition.
`
`Future Printings and Editions
`
`Every effort has been made to ensure the accuracy
`and completeness of this book. If you find an error,
`think that an entry does not contain enough infor-
`mation, or seek an entry that does not appear in this
`edition, please let us know. Address your letter to:

`

`ALGOl. \al’g~il, al’g61\ n. Short for Algorithmic
`Language. The first structured procedural pro-
`gramming language, developed in the late 1950s
`and once widely used in Europe.
`algorithm \al’go-ridh’~m\ n. A finite sequence
`of steps for solving a logical or mathematical
`problem.
`algorithmic language \al’ga-ridh’mik lang’waj\
`n. A programming language, such as Ada, Basic,
`C, or Pascal, that uses algorithms for problem
`solving.
`alias \~’l~-as, gl’yos\ n. 1. An alternative label for
`some object, such as a file or data collection. 2. A.
`name used to direct e-mail messages to a person
`or group of people on a network. 3. A false signal
`that results from the digitization of an analog
`audio sample.
`aliasing \~’l~-a-s~ng’, ~.l’ya-s~ng’\ n. In computer
`graphics, the jagged appearance of curves or diag-
`onal lines on a display screen, which is caused by
`low screen resolution. See the illustration.
`
`Aliasing. The lower resolution of the image on the
`right reveals the aliasing effect.
`
`allasing bug \~.’l~-as-~ng bug’, fil’yo-s~ng\ n. A
`class of subtle programming errors that can arise
`in code that performs dynamic allocation. If sev-
`eral pointers address the same chunk of storage,
`the program may free the storage using one of
`the pointers, but then attempt to use another
`one (an alias), which would no longer be point-
`ing to the desired data. This bug is avoidable by
`the use of allocation strategies that never use
`more than one copy of a pointer to allocated
`core memory, or by the use of higher-level lan-
`guages, such as LISP, which employ a garbage
`collection feature. Also called stale pointer bug.
`See also alias, dynamic allocation, garbage
`collection.
`align \a-l~n’\ vb. 1. [n an application such as a
`word processor, to position lines of type relative
`
`to some point, such as the page margin. The most
`common types of alignment are shown.

`2. To adjust some device to position it within speci-
`fied tolerances, such as the read/write head relative
`to a track on a disk. 3. In data handling, to store mul-
`tiple-byte data units so that the respective bytes fall
`in corresponding locations of memory.
`alignment \o-lTn’mant\ n. The arrangement of
`objects in fixed or predetermined positions, rows,
`or columns. For example, the Macintosh Finder
`can do automatic alignment of icons in a folder or
`on the desktop.

`as sufficient memory, for use by a program. Com-
`pare deallocate.
`allocation \al’a-k~’shan\ n. In operating systems,
`the process of reserving memory for use by a pro-
`gram.
`allocation block size \al-a-k~’shan blok" sgz\ n.

`medium, such as a hard drive, which is deter-
`mined by factors such as total disk size and parti-
`tioning options.
`allocation unit \al’a-k~’shan y~)’nit\ n. See
`cluster.
`all points addressable \~il" points a-dres’a-bl\ n.
`The mode in computer graphics in which all pixels
`can be individually manipulated. Acronym: APA

`microprocessor product introduced in February
`1992 as the DECchip 21064. For trademark rea-
`sons, DEC has expanded the name to Alpha AXP,
`used as an adjective to describe the DECchip tech-

`

`which have speeds of 500 kilobits per second
`(Kbps), can generally transmit data faster than cur-
`rent conventional modems. See also coaxial cable,
`modem.
`cabling diagram \k~’bo-l~ng d~’a-gram\ n. A
`plan that shows the path of cables that attach com-
`puter system components or peripherals. Cabling
`diagrams are particularly important for explaining
`the connection of disk drives to a disk controller.
`cache \kash\ n. A special memo13r subsystem in
`which frequently used data values are duplicated
`for quick access. A memory cache stores the con-
`tents of frequently accessed RAM locations and the
`addresses where these data items are stored. When
`the processor references an address in memory, the
`cache checks to see whether it holds that address.
`If it does hold the address, the data is returned to
`the processor; if it does not, a regular memory
`access occurs. A cache is useful when RAM accesses
`are slow compared with the microprocessor speed,
`because cache memow is always faster than main
`RAM memory. See also disk cache, wait state.
`cache card \kash" k~rd\ n. An expansion card
`that increases a system’s cache memory. See also
`cache, expansion board.
`cache memory \kash" mere’or-e\ n. See cache.
`CAD \kad, C’A-D*\ n. Acronym for computer-
`aided design. A syste~n of programs and worksta-
`tions used in designing engineering, architectural,
`and scientific models ranging from simple tools to
`buildings, aircraft, integrated circuits, and mole-
`cules. Various CAD applications create objects in
`two or three dimensions, presenting the results as
`wire-frame "skeletons," as more substantial models
`with shaded surfaces, or as solid objects. Some pro-
`grams can also rotate or resize models, show inte-
`rior views, generate lists of materials required for
`construction, and perform other allied functions.
`CAD programs rely on mathematics, often requi>
`ing the computing power of a high-performance
`workstation. See also CAD/CAM, I-CASE.
`CAD/CAM \kad’kam, C-A-D’C-A-M’\ n. Acronym
`for compute>aided design/computer-aided man-
`ufacturing. The use of computers in both the
`design and manufacture of a product. With CAD/
`CAM, a product, such as a machine part, is
`designed with a CAD program and the finished
`design is translated into a set of instructions that
`
`can be transmitted to and used by the machines
`dedicated to fabrication, assembly, and process
`control. See also CAD, I-CASE.
`(;ADD \C’A-D-D", kad-D’\ n. See computer-aided
`design and drafting.
`caddy \kad’{\ n. A plastic carrier that holds a CD-
`ROM and is inserted into a CD-ROM drive. Some
`personal computers, especially older models, have
`CD-ROM drives that require the use of a caddy.
`Most current CD-ROM drives do not require a
`caddy. See the illustration.

`
`CAE \C’A-E’\ n. Acronym for computer-aided
`engineering. An application that enables the user
`to perform engineering tests and analyses on
`designs created with a computer. In some
`instances, capabilities such as logic testing that are
`generally attributed to CAE applications are also
`part of CAD programs, so the distinction between
`CAD and CAE is not a hard-and-fast one. See also
`CAD, I-CASE.
`CAI \C’A-I’\ n. Acronym for compute>aided (or
`compute>assisted) instruction. An educational
`program designed to serve as a teaching tool. CAI
`programs typically use tutorials, drills, and ques-
`tion-and-answer sessions to present a topic and to
`test the student’s comprehension. CAI programs
`are excellent aids for presenting factual material
`and for allowing studeiats to pace their learning
`speed. Subjects and complexity range from begin-
`ning arithmetic to advanced mathematics, science,
`history, computer studies, and specialized topics.
`See also I-CASE. Compare CBT, CMI.
`CAL \C’A-L’\ n. Acronym for computer-assisted
`(or computer-augmented) learning. See CAI.

`
`various operations. These symbols are connected
`by lines and arrows to indicate the flow of data or
`control from one point to another. Flowcharts are
`used both as aids in showing the -way a proposed
`program will work and as a means of understand-
`
`ing the operations of an existing program. See the
`illustration.
`.fl.us \dot-F-L’dot-U-S’\ n. On the Internet, the
`major geographic domain specifying that an
`address is located in Florida, United States.
`flush1 \flush\ adj. Aligned in a certain way on
`
`the screen or on paper. Flush left, for example,
`means aligned on the left side; flush right means
`aligned on the right side. See also align (defini-
`tion 1).
`flush2 \flush\ vb. To clear a portion of memory.
`For example, to flush a disk file buffer is to save
`its contents on disk and then clear the buffer for
`filling again.
`flux \fluks\ n. 1. The total strength of a magnetic,
`electric, or radiation field over a given area. 2. A
`chemical used to aid the binding of solder to elec-
`trical conductors.
`flux reversal \fluks" r0-var’sal\ n. The change in
`orientation of the minute magnetic particles on the
`surface of a disk or tape toward one of two mag-
`netic poles. The two different alignments are used
`to represent binalT 1 and binary 0 for data storage:
`a flux reversal typically represents a binary 1, and
`no reversal represents a binary 0.
`.fm \dot’F-M’\ n. On the Intemet, the major geo-
`graphic domain specifying that an address is
`located in Micronesia.
`FM \F-M’\ n. See frequency modulation.
`FM encoding \F-M" en-k6"d{ng\ n. See frequency
`modulation encoding.
`.fo \dot’F-O’\ n. On the Intemet, the major geo-
`graphic domain specifying that an address is
`located in the Faeroe Islands.
`focus \f6"kus,\ vb. In television and raster-scan
`displays, to make an electron beam converge at a
`single point on the inner surface of the screen.

`Computing in the United States.
`FOD \F’O-D’\ n. See fax on demand.
`folder \f61"dor\ n. In the Mac OS, Windows 95,
`and other operating systems, a container for’ pro-
`
`grams and files in graphical user interfaces, sym-
`bolized on the screen by a graphical image (icon)
`of a file folder. This container is called a directory
`in other systems, such as MS-DOS and UNIX. A
`folder is a means of organizing programs and
`documents on a disk and can hold both files and

`additional folders. It first appeared commercially
`in Apple Computer’s Lisa in 1983 and in the Apple
`Macintosh in 1984. See also directory.
`folio \f6"1~-6"\ n. A printed page number.
`follow-up \fol’6-up’\ n. A post to a newsgroup
`that replies to an article. The follow-up has the
`same subject line as the original article, with the
`prefix "Re:" attached. An article and all of its fol-
`low-ups, in the order they were received, consti-
`tute a thread, which a user can read together using
`a newsreader.
`font \font\ n. A set of characters of the same type-
`face (such as Garamond), style (such as italic), and
`weight (such as bold). A font consists of all the
`characters available in a particular style and weight
`for a particular design; a typeface consists of the
`design itself. Fonts are used by computers for on-
`screen displays and by printers for hard-copy out-
`put. In both cases, the fonts are stored either as bit
`maps (patterns of dots) or as outlines (defined by
`a set of mathematical formulas). Even if the system
`cannot simulate different typefaces on the screen,
`application programs may be able to send infor-
`mation about typeface and style to a printer, which
`can then reproduce the font if a font description is
`available. See also bit map, font generator.
`font card \font" k~rd\ n. See font cartridge, RUM
`card.
`font cartridge \font" Mir’trij\ n. A plug-in unit
`available for some printers that contains fonts in
`several different styles and sizes. Font cartridges;
`like downloadable fonts, enable a printer to pro-
`duce characters in sizes and styles other than those
`created by the fonts built into it. Also called font
`card. See also RUM cartridge.
`Font/DA Mover \font’D-A~ m~’var\ n. An appli-
`cation for older Apple Macintosh systems that
`allows the user to install screen fonts and desk
`accessories.
`font editor \font" ed’a-tor\ n. A utility program
`that enables the user to modify existing fonts or to
`create and save new ones. Such an application
`commonly works with a screen representation of
`the font, with a representation that can be down-
`loaded to a PostScript or other printer, or with
`both. See also PostScript font, screen font.
`font family \font" fam’a-l~\ n. The set of available
`fonts representing Variations of a single typeface.
`
`For example, Times Roman and Times Roman
`Italic are members of the same font family. When
`the user indicates "italic," the system selects the
`correct italic font for the font family, with its char-
`acteristic appearance. If there is no italic font in
`the family, the system simply slants, or "obliques,"
`the corresponding roman character. See also italic,
`roman.
`font generator \font" jen’ar-fi-tar\ n. A program
`that transforms built-in character outlines into bit
`maps (patterns of dots) of the style and size
`required for a printed document. Font generators
`work by scaling a character outline to size; often
`they can also expand or compress the characters
`they generate. Some font generators store the
`resultant characters on disk; others send them
`directly to the printer.
`font number \font" num’bar\ n. The number by
`which an application or operating system inter-
`nally identifies a given font. On the Apple Macin-
`tosh, for example, fonts can be identified by their
`exact names as well as their font numbers, and a
`font number can be changed if the font is installed
`in a system already having a font with that num-
`ber. See also font.
`font page \font" p~j\ n. A portion of video mem-
`ory reserved for holding programmer-specif
