World Wide Web Worm
The World Wide Web Worm (WWWW) was one of the earliest search engines for the World Wide Web (WWW). It is claimed by some to be the first search engine, though it was not released until March 1994, by which time a number of other search engines had been made publicly available. It was developed in September 1993 by Oliver McBryan at the University of Colorado as a research project. The worm created a database of 300,000 multimedia objects which could be obtained or searched for keywords via the WWW. It indexed about 110,000 webpages as of 1994. In contrast to present-day search engines, the WWWW featured support for Perl regular expressions. The website, http://www.cs.colorado.edu/home/mcbryan/WWWW.html, is no longer accessiblearchive. Circa 1997 Goto.com purchased WWWW's technology. McBryan stated in a 2016 podcast that WWWW was an educational project and he never thought of commercializing it like Excite or Yahoo! Yahoo! (, styled yahoo''!'' in its logo) is an American ...

Search Engine
A search engine is a software system designed to carry out web searches. They search the World Wide Web in a systematic way for particular information specified in a textual web search query. The search results are generally presented in a line of results, often referred to as search engine results pages (SERPs). When a user enters a query into a search engine, the engine scans its index of web pages to find those that are relevant to the user's query. The results are then ranked by relevancy and displayed to the user. The information may be a mix of links to web pages, images, videos, infographics, articles, research papers, and other types of files. Some search engines also mine data available in databases or open directories. Unlike web directories and social bookmarking sites, which are maintained by human editors, search engines also maintain real-time information by running an algorithm on a web crawler. Any internet-based content that can't be indexed and searched ...

World Wide Web
The World Wide Web (WWW), commonly known as the Web, is an information system enabling documents and other web resources to be accessed over the Internet. Documents and downloadable media are made available to the network through web servers and can be accessed by programs such as web browsers. Servers and resources on the World Wide Web are identified and located through character strings called uniform resource locators (URLs). The original and still very common document type is a web page formatted in Hypertext Markup Language (HTML). This markup language supports plain text, images, embedded video and audio contents, and scripts (short programs) that implement complex user interaction. The HTML language also supports hyperlinks (embedded URLs) which provide immediate access to other web resources. Web navigation, or web surfing, is the common practice of following such hyperlinks across multiple websites. Web applications are web pages that function as application s ...

Perl
Perl is a family of two high-level, general-purpose, interpreted, dynamic programming languages. "Perl" refers to Perl 5, but from 2000 to 2019 it also referred to its redesigned "sister language", Perl 6, before the latter's name was officially changed to Raku in October 2019. Though Perl is not officially an acronym, there are various backronyms in use, including "Practical Extraction and Reporting Language". Perl was developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier. Since then, it has undergone many changes and revisions. Raku, which began as a redesign of Perl 5 in 2000, eventually evolved into a separate language. Both languages continue to be developed independently by different development teams and liberally borrow ideas from each other. The Perl languages borrow features from other programming languages including C, sh, AWK, and sed; They provide text processing facilities without the arbitrary data-le ...

Regular Expressions
A regular expression (shortened as regex or regexp; sometimes referred to as rational expression) is a sequence of characters that specifies a search pattern in text. Usually such patterns are used by string-searching algorithms for "find" or "find and replace" operations on strings, or for input validation. Regular expression techniques are developed in theoretical computer science and formal language theory. The concept of regular expressions began in the 1950s, when the American mathematician Stephen Cole Kleene formalized the concept of a regular language. They came into common use with Unix text-processing utilities. Different syntaxes for writing regular expressions have existed since the 1980s, one being the POSIX standard and another, widely used, being the Perl syntax. Regular expressions are used in search engines, in search and replace dialogs of word processors and text editors, in text processing utilities such as sed and AWK, and in lexical analysis. Most gener ...

Goto
GoTo (goto, GOTO, GO TO or other case combinations, depending on the programming language) is a statement found in many computer programming languages. It performs a one-way transfer of control to another line of code; in contrast a function call normally returns control. The jumped-to locations are usually identified using labels, though some languages use line numbers. At the machine code level, a goto is a form of branch or jump statement, in some cases combined with a stack adjustment. Many languages support the goto statement, and many do not (see § language support). The structured program theorem proved that the goto statement is not necessary to write programs that can be expressed as flow charts; some combination of the three programming constructs of sequence, selection/choice, and repetition/iteration are sufficient for any computation that can be performed by a Turing machine, with the caveat that code duplication and additional variables may need to be introduce ...

Excite (web Portal)
Excite is an American web portal operated by IAC that provides a variety of outsourced content including news and weather, a metasearch engine, and a user homepage. In the United States, the main Excite homepage had long been a personal start page called My Excite. Excite once operated a webmail service commonly known as Excite Mail until August 31, 2021. The original Excite company was founded in 1994 and went public two years later. Excite was once a popular site on the Internet during the 1990s, with the main portal site Excite.com being the sixth most visited website in 1997. The company merged with broadband provider @Home Network but together went bankrupt in 2001. Excite's portal and services were acquired by iWon and then by Ask Jeeves, but the website went into a steep decline in popularity afterwards. History Excite originally started as Architext in June 1993 at a garage in Cupertino, California, created by Graham Spencer, Joe Kraus, Mark VanHaren, Ryan McIntyre, B ...

First International Conference On The World Wide Web
The First International Conference on the World-Wide Web (also known as WWW1) was the first-ever conference about the World Wide Web, and the first meeting of what became the International World Wide Web Conference. It was held on May 25 to 27, 1994 in Geneva, Switzerland. The conference had 380 participants, who were accepted out of 800 applicants. It has been referred to as the "Woodstock of the Web". The event was organized by Robert Cailliau, a computer scientist who had helped to develop the original WWW specification, and was hosted by CERN. Cailliau had lobbied inside CERN, and at conferences like the ACM Hypertext Conference in 1991 (in San Antonio) and 1993 (in Seattle). After returning from the Seattle conference, he announced the new World Wide Web Conference 1. Coincidentally, the NCSA announced their Mosaic and the Web conference 23 hours later. Content Dave Raggett showed his testbed web browser Arena and gave a summary of his first HTML+ Internet Draft. He also s ...
