''Computer Technical Words : How Its Named''

1. Ada - a programming language named after Ada Lovelace, who is considered by many to be the first programmer.

2. CPU - An acronym for Central Processing Unit and is often used to refer to a computer system, such as “That beige box sitting next to my 24” flat screen monitor is my new CPU.” The “beige box” being referred to in the aforementioned statement is a computer system and not a CPU, the CPU is the chip inside the computer system known specifically as the microprocessor. Prior to the invention of the microprocessor in 1971 by Intel (the 4004) CPU’s were circuits consisting of many chips to make up the function of a programmable information processing and manipulation device.

3. Linux - an operating system kernel, and the common name for the operating system which uses it.
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.

4. C - a programming language named because Dennis Ritchie improved on the B language and called it New B. He later called it C

5. BASIC - In computer programming, BASIC (an acronym which stands for Beginner's All-purpose Symbolic Instruction Code) is a family of high-level programming languages designed to be easy to use.

6. JavaScript - a programming language
It was originally developed by Brendan Eich of Netscape under the name Mocha, which was later renamed to Live Script, and finally to JavaScript. 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.

7. Java - a programming language.
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 indeed 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."

8. Red Hat Linux - a Linux distribution from Red Hat.
Company founder Marc Ewing was given the Cornell lacrosse team cap (with red and white stripes) while at college by his grandfather. 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 had an appeal to readers to return his Red Hat if found by anyone.

9. Google - search engine on the web.
The name started as an exaggerated boast about the amount of information the search-engine would be able to search. It was originally named 'Googol', a word for the number represented by 1 followed by 100 zeros. The word was originally invented by Milton Sirotta, nephew of mathematician Edward Kasner in 1938 during a discussion of large numbers and exponential notation.

10. Daemon - a process in an operating system that runs in the background.
It is falsely considered an acronym for Disk And Execution MONitor. 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)" thus evading the Laws of Thermodynamics. The earliest use appears to have been in the phrase "daemon of Socrates", which meant his "guiding or indwelling spirit; his genius", also a pre-Christian equivalent of the "Guardian Angel", or, alternatively, a demigod (who bears only an etymological connection to the word "demon"). The term was embraced, and possibly popularized, 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 (copyright Marshall Kirk McKusick). Thus, a daemon is something that works magically without anyone being much aware of it. Note that an alternative spelling is 'daemon', which is sometimes slightly differentiated in purpose from 'demon'.

11. C++ - an object-oriented programming language and a successor to the C programming language. C++ creator Bjarne Stroustrup called his new language "C with Classes" and then "new C". Because of which the original C began to be called "old C" which was considered insulting to the C community. At this time Rick Mascitti suggested the name C++ as a successor to C. In C the '++' operator increments the value of the variable it is appended to, thus C++ would increment the value of C.

12. Booting or bootstrapping - The term booting or bootstrapping a computer was inspired by the story of the Baron Münchhausen where he pulls himself out of a swamp by the straps on his boots.

13. PHP - a server-side scripting language.
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.

14. 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".

15. Spam - unwanted repetitious messages, such as unsolicited bulk e-mail.
The term spam is derived from the Monty Python SPAM sketch, set in a cafe 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.

16. 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 "Experiments with Computer Viruses", 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.

17. Zip - a file format now also used as a verb to mean compress. 
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.

18. Yahoo! - internet portal and web directory.
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, 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.

19. Bit - Claude E. Shannon first used the word bit in a 1948 paper. Shannon's bit is a portmanteau word for binary digit (or possibly binary digit). He attributed its origin to John W. Tukey.

20. Worm - a self-replicating program, similar to a virus.
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.
