User:Moogsi/List of computer term etymologies

From Wikipedia, the free encyclopedia

This is a list of the origins of computer-related terms or terms used in the computing world (i.e., a list of computer term etymologies). It relates to both computer hardware and computer software.

Names of many computer terms, especially computer applications, often relate to the function they perform, e.g., a compiler is an application that compiles (programming language source code into the computer's machine language). However there are other terms with less obvious origins, which are of etymological interest. This article lists such terms.

A

[edit]
  • ABEND — originally from an IBM System/360 error message, short for "abnormal end". Jokingly reinterpreted as German Abend ("evening"), because "it is what system operators do to the machine late on Friday when they want to call it a day."[1]
  • Apache — originally chosen from respect for the Native American Indian tribe of Apache. It was suggested that the name was appropriate, as Apache began as a series of patches to code written for NCSA's HTTPd daemon. The result was "a patchy" server.[2]

B

[edit]
The first case of an actual computer bug, a moth trapped in a relay of the Harvard Mark II
  • biff — named after a dog known by the developers at Berkeley, who – according to the UNIX manual page – died on the 15th August 1993, at the age of 15, and belonged to a certain Heidi Stettner. Some sources[5][6] report that the dog would bark at the mail carrier, making it a natural choice for the name of a mail notification system. The Jargon File contradicts this[7], but confirms at least that the dog existed.
  • Bon — created by Ken Thompson and named either after his wife Bonnie, or else after "a religion whose rituals involve the murmuring of magic formulas" (a reference to the Tibetan native religion Bön).[4]
  • booting or bootstrapping — from the phrase "to pull oneself up by one's bootstraps", originally used as a metaphor for any self-initiating or self-sustaining process. Used in computing due to the apparent paradox that a computer must run code to load anything into memory, but code cannot be run until it is loaded.
  • bug — often (but erroneously) credited to Grace Hopper. In 1946, she joined the Harvard Faculty at the Computation Laboratory where she traced an error in the Harvard Mark II to a moth trapped in a relay. This bug was carefully removed and taped to the log book. However, use of the word 'bug' to describe defects in mechanical systems dates back to at least the 1870s, perhaps especially in Scotland.[citation needed] Thomas Edison, for one, used the term in his notebooks.[citation needed]
  • byte — coined by Werner Buchholz in 1956 during the early design phase for the IBM Stretch computer. It was coined by mutating the word bite so it would not be accidentally misspelled as bit.

C

[edit]
Computer room at Dryden Flight Research Center, 1949
  • C — Dennis Ritchie, having improved on B, called his creation New B. He later renamed it C. (See also D).
  • C++ — creator Bjarne Stroustrup called his new language "C with Classes" and then "new C". The original language began to be called "old C" which was considered insulting to the C community. At this time Rick Mascitti suggested the name "C++" – in C the  ++  operator increments the value of the variable it is appended to, thus  C++  would increment the value of the variable  C .

D

[edit]
  • D — designed by Walter Bright as an improved C, avoiding many of the design problems of C (e.g., extensive pointer manipulation, unenforced array boundaries, etc.).
  • daemon — falsely considered an acronym for Disk And Execution Monitor.[by whom?] According to the original team that introduced the concept, "the use of the word daemon was inspired by the Maxwell's demon of physics and thermodynamics (an imaginary agent which helped sort molecules with differing velocities and worked tirelessly in the background)"[citation needed] The term was embraced, and possibly popularized[citation needed], by the Unix operating systems which supported multiple background processes: various local (and later Internet) services were provided by daemons. This is exemplified by the BSD mascot, John Lasseter's drawing of a friendly imp.

F

[edit]
  • finger — Les Earnest wrote the finger program in 1971 to provide for users who wanted information about other users on a network or system. Before the finger program, the only way to get this information was with the who program that showed IDs and terminal line numbers for logged-in users; people used to run their fingers down the "who" list. Earnest named his program after this phenomenon.

G

[edit]
Gentoo Linux is named after the penguin
  • Google — started as an exaggerated boast about the amount of information the search engine would be able to index. It was originally named 'Googol', a word for the number represented by 1 followed by 100 zeros, coined by Milton Sirotta, nephew of mathematician Edward Kasner, in 1938 during a discussion of large numbers and exponential notation.
  • Gopher — the source of the name is claimed to be three-fold: first, that it is used to "go-for" information; second, that it does so through a menu of links analogous to gopher holes; and third, that the mascot of the protocol authors' organization, the University of Minnesota, is Goldy the Gopher.
  • grep — from a command in the Unix text editor ed that takes the form g/re/p meaning search globally for a regular expression and print lines where instances are found. "Grep", like "Google", is often used as a verb, meaning "to search".

H

[edit]
  • Hotmail founder Jack Smith got the idea of accessing e-mail via the web from a computer anywhere in the world. When Sabeer Bhatia came up with the business plan for the mail service, he tried all kinds of names ending in 'mail' and finally settled for "Hotmail" as it included the letters "HTML" — the markup language used to write web pages. It was initially referred to as "HoTMaiL" with selective upper casing.

I

[edit]
  • i18n — short for "internationalization". "18" is for the number of letters between the i and the n. The term l10n (for "localization") has failed to catch on to the same degree, but is used by some.
  • ICQ — ICQ is not an initialism. It is a play on the phrase "I seek you" (similar to CQ in ham radio usage).
  • ID10T - pronounced "I D ten T" - is a code frequently used by a customer service representative (CSR) to annotate their notes and identify the source of a problem as the person who is reporting the problem rather than the system being blamed. This is a thinly veiled reference to the CSR's opinion that the person reporting the problem is an IDIOT. Example: Problem reported caused by ID10T, no resolution possible. See also PEBKAC.

J

[edit]
  • Jakarta Project — Jakarta was the name of the conference room at Sun where most of the meetings between Sun and Apache took place. The conference room was most likely named after Jakarta, the capital city of Indonesia, which is located on the northwest coast of the island of Java.
  • Java Originally called "D", but with the connotation of a near-failing mark on a report card the language was renamed "Oak" by Java creator James Gosling, from the tree that stood outside his window. The programming team at Sun had to look for a substitute name as there was already another programming language called Oak. "Java" was selected from a list of suggestions, primarily because it is a popular slang term for coffee, especially that grown on the island of Java. As the programmers drank a lot of coffee, this seemed an appropriate name. Many people mistakenly think that Java is an acronym and spell it JAVA. When one of the original Java programmers from Sun was asked to define JAVA he said it stood for nothing, but if it must stand for something: "Just Another Vague Acronym."
  • JavaScript — originally developed by Brendan Eich of Netscape under the name "Mocha", which was later renamed to "LiveScript", and finally to "JavaScript".[13] The change of name from LiveScript to JavaScript roughly coincided with Netscape adding support for Java technology in its Netscape Navigator web browser. JavaScript was first introduced and deployed in the Netscape browser version 2.0B3 in December 1995. The naming has caused confusion, giving the impression that the language is a spin-off of Java, and it has been characterized by many as a marketing ploy by Netscape to give JavaScript the cachet of what was then the hot new web-programming language.[14][15]

K

[edit]
  • Kerberos — at MIT in the 1970s, the protocol's creators wanted a name that suggested high security for the project, so they named it after Kerberos, in Greek mythology the three-headed dog guarding the gates of Hades. The reference to Greek mythology is most likely because Kerberos was developed as part of Project Athena.

L

[edit]
  • Linux — Linux creator Linus Torvalds originally used the Minix operating system on his computer, didn't like it, liked MS-DOS less, and started a project to develop an operating system that would address the problems of Minix. Hence the working name was Linux (Linus' Minix). Originally, however, Linus had planned to have it named Freax (free + freak + x). His friend Ari Lemmke encouraged Linus to upload it to a network so it could be easily downloaded. Ari gave Linus a directory called linux on his FTP server, as he did not like the name Freax.
  • Lisa — Apple Computer stated that Lisa was an acronym for Local Integrated Software Architecture; however, it is often inferred that the machine was originally named after the daughter of Apple co-founder Steve Jobs, and that this acronym was invented later to fit the name. Accordingly, two humorous suggestions for expanding the acronym included Let's Invent Some Acronym and Let's Invent Silly Acronyms.
  • liveware - a play on the terms "software" and "hardware". Coined in 1966, the word indicates that sometimes a computer problem is not with the computer itself, but with the user.

M

[edit]
The original apple McIntosh
  • modem — a contraction of "modulator/demodulator", a simple description of its function.

N

[edit]
  • nerd — earlier spelling of the term is "Nurd" and the original spelling is "Knurd", but the pronunciation has remained the same. The term originated at Rensselaer Polytechnic Institute in the late 1940s. Students who partied, and rarely studied were called "Drunks", while the opposite — students who never partied and always studied were "Knurd" ("Drunk" spelled backwards). The term was also (independently) used in a Dr. Seuss book, and on the TV show Happy Days, giving it international popularity.
  • Novell — Novell, Inc. was originally Novell Data Systems co-founded by George Canova. The name was suggested by George's wife who mistakenly thought that "novell" meant "new" in French.

O

[edit]
  • OLIVER — the name of this software, which prevented CICS system abends caused by applications programs, did not originate from "Online Verification" or similar. It was the name of the author's son Oliver.
  • Oracle — Larry Ellison, Ed Oates and Bob Miner were working on a consulting project for the CIA (Central Intelligence Agency). The code name for the project was called Oracle (the CIA evidently saw this as a system that would give answers to all questions). The project was designed to use the newly written SQL database language from IBM. The project eventually was terminated but they decided to finish what they started and bring it to the world. They kept the name Oracle and created the RDBMS engine.

P

[edit]
  • Pac-Man — from paku paku, Japanese onomatopoeia used for noisy eating; similar to chomp chomp. The game was released in Japan with the name Puck-Man, and released in the US with the name Pac-Man, fearing that kids may deface a Puck-Man cabinet by changing the P to an F.
  • PCMCIA — the Personal Computer Memory Card International Association is an international standards body that defines and promotes standards for expansion devices such as modems and external hard disk drives to be connected to notebook computers. Over time, the acronym PCMCIA has been used to refer to the PC card form factor used on notebook computers. A twist on the acronym is People Can't Memorize Computer Industry Acronyms.
  • PEBKAC - an acronym for "Problem Exists Between Keyboard And Chair", which is a code frequently used by a customer service representative (CSR) to annotate their notes and identify the source of a problem as the person who is reporting the problem rather than the system being blamed. This is a thinly veiled reference to the CSR's opinion that the person reporting the problem is the problem. Example: PEBKAC, no resolution possible. See also ID10T.
  • Pentium — as the fifth microprocessor in the 80x86 series, the original Pentium was to be called i586 or 80586, but was named "Pentium" (penta = five) ny Intel after it lost a trademark infringement lawsuit against AMD due to a judgment that numbers like "286", "386", and "486" cannot be trademarked. According to Intel, Pentium conveys a meaning of strength, like titanium.
Since some early Pentium chips contained a mathematical precision error, it has been jokingly suggested that the reason for the chip being named Pentium rather than 586 was that Intel chips would calculate 486 + 100 = 585.99999948.
  • Perl — Perl was originally named Pearl, after the "pearl of great price" of Matthew 13:46. Larry Wall, the creator of Perl, wanted to give the language a short name with positive connotations and claims to have looked at (and rejected) every three- and four-letter word in the dictionary. He even thought of naming it after his wife Gloria. Before the language's official release Wall discovered that there was already a programming language named Pearl, and changed the spelling of the name. Although the original manuals suggested the backronyms "Practical Extraction and Report Language" and "Pathologically Eclectic Rubbish Lister", these were intended humorously.
  • PHP — Originally called "Personal Home Page Tools" by creator Rasmus Lerdorf, it was rewritten by developers Zeev Suraski and Andi Gutmans who gave it the recursive name "PHP Hypertext Preprocessor". Lerdorf currently insists the name should not be thought of as standing for anything, for he selected "Personal Home Page" as the name when he did not foresee PHP evolving into a general-purpose programming language.
  • Pine — many people believe that Pine stands for "Pine Is Not Elm". However, one of its original authors, Laurence Lundblade, insists this was never the case and that it started off simply as a word and not an acronym; his first choice of a backronym for pine would be "Pine Is Nearly Elm". Over time it was changed to mean Program for Internet News and E-mail.[16]
  • ping — the author of ping, Mike Muuss, named it after the pulses of sound made by a sonar called a "ping". Later Dave Mills invented the backronym "Packet Internet Groper".

R

[edit]
  • Radio button — named after the preset buttons on radio receivers. When one used to select preset stations on a radio receiver physically instead of electronically, depressing one preset button would pop out whichever other button happened to be pushed in.
  • Red Hat Linux — company founder Marc Ewing was given the Cornell lacrosse team cap (with red and white stripes) by his grandfather while at college. People would turn to him to solve their problems, and he was referred to as "that guy in the red hat". He lost the cap and had to search for it desperately. The manual of the beta version of Red Hat Linux contained an appeal to readers to return the hat if found.

S

[edit]
  • Samba — the name "Samba" comes from inserting two vowels into SMB, the name of the standard protocol that Microsoft Windows network file system uses. The author searched a dictionary using grep for words containing S, M, and B in that order; the only matches were Samba and Salmonberry[citation needed].
  • shareware — coined by Bob Wallace to describe his word processor PC-Write in early 1983. Before this Jim Knopf (also known as Jim Button) and Andrew Fluegelman called their distributed software "user supported software" and "freeware" respectively, but it was Wallace's terminology that prevailed.
  • SIMON - the name of this instruction set simulator software - that allowed batch application programs to be tested interactively from online terminals - did not originate from "Simulation Online" or similar. It was the name of the author's other son (see also OLIVER).
  • Slashdot — while registering the domain, Slashdot-creator Rob Malda wanted to make the URL silly and unpronounceable ("http://slashdot.org" gets pronounced as "h t t p colon slash slash slash dot dot org"). Alternatively, many say that the Slashdot (/.) name refers to the *NIX command line interpretation of the "root" directory, or a play on the website being the "root" of all tech news.
  • sosumi — Apple Computer has had a long litigation history with Apple Records, The Beatles' recording company. Fearing that the ability to record musical sound would cause yet more legal action, the Apple legal department allegedly ordered this sound to be renamed from its original, musical name.[citation needed] So the developers changed the name to sosumi ("so sue me"). Depending on who was asked, they quipped that it was Japanese for either "absence of sound" or "a light pleasing tone".[citation needed]
  • spam — derived from the Monty Python SPAM sketch, set in a café where everything on the menu includes SPAM luncheon meat. While a customer plaintively asks for some kind of food without SPAM in it, the server reiterates the SPAM-filled menu. Soon, a chorus of Vikings join in with a song: "SPAM, SPAM, SPAM, SPAM, SPAM, lovely SPAM, wonderful SPAM", over and over again, drowning out all conversation.
  • SPIM — a simulator for a virtual machine closely resembling the instruction set of MIPS processors, is simply MIPS spelled backwards. In recent time, spim has also come to mean SPam sent over Instant Messaging.
  • Swing — a graphics library for Java. "Swing" was the code-name of the project that developed the new graphic components (the successor of AWT). It was named after swing, a style of dance band jazz. Although an unofficial name for the components, it gained popular acceptance with the use of the word in the package names for the Swing API, which begin with  javax.swing.

T

[edit]
  • Tomcat — Tomcat was the code-name for the JSDK 2.1 project inside Sun Microsystems. It began as a servlet specification implementation by James Duncan Davidson, a software architect at Sun, who initially hoped that the project would be made open-source. Since most open-source projects had O'Reilly books on them with an animal on the cover, he wanted to name the project after an animal. He came up with Tomcat since he reasoned the animal represented something that could take care of and fend for itself.
  • troff — a document processing system for Unix. Troff stands for "typesetter roff", although many people have speculated that it actually means "Times roff" because of the use of the Times font family in troff by default. Troff has its origins from Roff, an earlier formatting program, whose name is a contraction of "run off".
  • Trojan horse — a malicious program that is disguised as legitimate software, named after the classical myth of the Trojan Horse. Analogously, a Trojan horse appears innocuous (or even to be a gift), but in fact is a vehicle for bypassing security.
  • Tux — The penguin now commonly regarded as the most famous logo of the Linux Kernel and its deviants. The logo was originally created by Larry Ewing in 1996 as an entry in a Linux Logo competition. The creator of Linux, Linus Torvalds was bitten by a Little Penguin during a visit to Canberra Zoo in 1993, which made the penguin his 'favourite' animal. The word Tux apparently comes from "(T)orvalds (U)ni(X)". Some people also observe that the first thing that comes to one's mind when looking at the black and white coat of the Penguin is a tuxedo.
  • TWAIN — a standard for acquiring data from image scanners. "Twain" is a dated word for "two". Although TWAIN is not an acronym, it has often been referred to as an acronym for "Technology Without An Intelligent Name".

U

[edit]
  • Unix — when Bell Labs pulled out of the MULTICS (MULTiplexed Information and Computing System) project, which was originally a joint Bell Labs/GE/MIT project, Ken Thompson of Bell Labs, soon joined by Dennis Ritchie, wrote a simpler version of the operating system for a spare DEC minicomputer, allegedly found in a corridor. They needed an OS to run the game Space War which had been compiled under MULTICS. The new OS was called UNICS — Uniplexed Operating and Computing System by Brian Kernighan. An alternative spelling was Eunuchs, it being a sort of 'reduced' MULTICS. It was later shortened to Unix.

V

[edit]
  • vi — initialism for visual, a command in the ex editor which helped users to switch to the visual mode from the ex mode. the first version was written by Bill Joy at UC Berkeley.
  • Vim — acronym for Vi improved. Vim added several features over the vi editor. However, Vim had started out as an imitation of Vi and was expanded as Vi imitation.
  • Virus — a piece of program code that spreads by making copies of itself. The term virus was first used as a technical computer science term by Fred Cohen in his 1984 paper "Computer Viruses Theory and Experiments", where he credits Len Adleman with coining it. Although Cohen's use of virus may have been the first academic use, it had been in the common parlance long before that. A mid-1970s science fiction novel by David Gerrold, When H.A.R.L.I.E. was One, includes a description of a fictional computer program called VIRUS that worked just like a virus (and was countered by a program called ANTIBODY). The term "computer virus" also appears in the comic book "Uncanny X-Men" No. 158, published in 1982. A computer virus's basic function is to insert its own executable code into that of other existing executable files, literally making it the electronic equivalent to the biological virus, the basic function of which is to insert its genetic information into that of the invaded cell, forcing the cell to reproduce the virus.

W

[edit]
Coined by Ward Cunningham, the creator of the wiki concept, who named them for the "wiki wiki" or "quick" shuttle buses at Honolulu Airport. Wiki wiki was the first Hawaiian term he learned on his first visit to the islands. The airport counter agent directed him to take the wiki wiki bus between terminals.
The name 'worm' was taken from a 1970s science fiction novel by John Brunner entitled The Shockwave Rider. The book describes programs known as "tapeworms" which spread through a network for the purpose of deleting data. Researchers writing an early paper on experiments in distributed computing noted the similarities between their software and the program described by Brunner, and adopted that name.
  • WYSIWYG - describes a system in which content during editing appears very similar to the final product.
Acronym for What You See Is What You Get, the phrase was originated by a newsletter published by Arlene and Jose Ramos, called WYSIWYG. It was created for the emerging Pre-Press industry going electronic in the late 1970s.

X

[edit]
X derives its name as a successor to a pre-1983 window system called the W Window System.

Y

[edit]
Yahoo!'s history site says the name is an acronym for "Yet Another Hierarchical Officious Oracle", but some remember that in its early days (mid-1990s), when Yahoo! lived on a server called akebono.stanford.edu, it was glossed as "Yet Another Hierarchical Object Organizer." The word "Yahoo!" was originally invented by Jonathan Swift and used in his book Gulliver's Travels. It represents a person who is repulsive in appearance and action and is barely human. Yahoo! founders Jerry Yang and David Filo selected the name because they considered themselves yahoos.

Z

[edit]
The file format was created by Phil Katz, and given the name by his friend Robert Mahoney. The compression tool Phil Katz created was called PKZIP. Zip means "speed", and they wanted to imply their product would be faster than ARC and other compression formats of the time.
