Wiki in the context of Web browser

Wiktionary (US: /ˈwɪkʃənɛri/ WIK-shə-nerr-ee, UK: /ˈwɪkʃənəri/ WIK-shə-nər-ee; rhyming with "dictionary") is a multilingual, web-based project to create a free content dictionary of terms (including words, phrases, proverbs, linguistic reconstructions, etc.) in a large number of natural languages and a number of artificial languages. These entries may contain definitions, images for illustration, pronunciations, etymologies, inflections, usage examples, quotations, related terms, and translations of terms into other languages, among other features. It is collaboratively edited by volunteers via a wiki. Its name is a portmanteau of the words wiki and dictionary. It is available in 198 languages and in Simple English. Like its sister project Wikipedia, Wiktionary is run by the Wikimedia Foundation, and is written collaboratively by volunteers, dubbed "Wiktionarians". Its wiki software, MediaWiki, allows almost anyone with access to the website to create and edit entries.

Because Wiktionary is not limited by print space considerations, most of Wiktionary's language editions provide definitions and translations of terms from many languages, and some editions offer additional information typically found in thesauri.

New media are communication technologies that enable or enhance interaction between users, as well as interaction between users and content. In the middle of the 1990s, the phrase "new media" became widely used as part of a sales pitch for the influx of interactive CD-ROMs for entertainment and education. The new media technologies, sometimes known as Web 2.0, include a wide range of web-related communication tools such as blogs, wikis, online social networking, virtual worlds, and other social media platforms.

The phrase "new media" refers to computational media that share material online and through computers. New media inspire new ways of thinking about older media. Media do not replace one another in a clear, linear succession, instead evolving in a more complicated network of interconnected feedback loops . What is different about new media is how they specifically refashion traditional media and how older media refashion themselves to meet the challenges of new media.

The Wikimedia Foundation, Inc. (WMF) is an American 501(c)(3) nonprofit organization headquartered in San Francisco, California, and registered there as a charitable foundation. The Foundation is most known for being the host of Wikipedia, one of the most visited websites in the world. It also hosts fourteen related open collaboration projects, and supports the development of MediaWiki, the wiki software which underpins them all. The foundation was established in 2003 in St. Petersburg, Florida by Jimmy Wales, as a non-profit way to fund Wikipedia and other wiki projects which had previously been hosted by Bomis, Wales' for-profit company.

The Wikimedia Foundation provides the technical and organizational infrastructure to enable members of the public to develop wiki-based content in languages across the world. The foundation does not write or curate any of the content on the projects themselves. Instead, this is done by volunteer editors, such as the Wikipedians. However, it does collaborate with a network of individual volunteers and affiliated organizations, such as Wikimedia chapters, thematic organizations, user groups and other partners.

Wikipedia is a free online encyclopedia written and maintained by a community of volunteers, known as Wikipedians, through open collaboration and the wiki software MediaWiki. Founded by Jimmy Wales and Larry Sanger in 2001, Wikipedia has been hosted since 2003 by the Wikimedia Foundation, an American nonprofit organization funded mainly by donations from readers. Wikipedia is the largest and most-read reference work in history.

Initially available only in English, Wikipedia exists in over 340 languages and is the world's ninth most visited website. The English Wikipedia, with over 7 million articles, remains the largest of the editions, which together comprise more than 66 million articles and attract more than 1.5 billion unique device visits and 13 million edits per month (about 5 edits per second on average) as of April 2024. As of September 2025, over 25% of Wikipedia's traffic comes from the United States, while Japan accounts for nearly 7%, and the United Kingdom, Germany and Russia each represent around 5%.

Wiki software (also known as a wiki engine or a wiki application) is collaborative software that runs a wiki, which allows the users to create and collaboratively edit pages or entries via a web browser. A wiki system is usually a web application that runs on one or more web servers. The content, including previous revisions, is usually stored in either a file system or a database. Wikis are a type of web content management system, and the most commonly supported off-the-shelf software that web hosting facilities offer.

There are dozens of actively maintained wiki engines. They vary in the platforms they run on, the programming language they were developed in, whether they are open-source or proprietary, their support for natural language characters and conventions, and their assumptions about technical versus social control of editing.

User-generated content (UGC), alternatively known as user-created content (UCC), is content generated by users of the Internet such as images, videos, audio, text, testimonials, software, and user interactions. Online content aggregation platforms such as social media, discussion forums and wikis by their interactive and social nature, no longer produce multimedia content but provide tools to produce, collaborate, and share a variety of content, which can affect the attitudes and behaviors of the audience in various aspects. This transforms the role of consumers from passive spectators to active participants.

User-generated content is used for a wide range of applications, including problem processing, news, entertainment, customer engagement, advertising, gossip, research and more. It is an example of the democratization of content production and the flattening of traditional media hierarchies. The BBC adopted a user-generated content platform for its websites in 2005, and Time magazine named "You" as the Person of the Year in 2006, referring to the rise in the production of UGC on Web 2.0 platforms. CNN also developed a similar user-generated content platform, known as iReport. There are other examples of news channels implementing similar protocols, especially in the immediate aftermath of a catastrophe or terrorist attack. Social media users can provide key eyewitness content and information that may otherwise have been inaccessible.

An online service provider (OSP) can, for example, be an Internet service provider, an email provider, a news provider (press), an entertainment provider (music, movies), a search engine, an e-commerce site, an online banking site, a health site, an official government site, social media, a wiki, or a Usenet newsgroup.

In its original more limited definition, it referred only to a commercial computer communication service in which paid members could dial via a computer modem the service's private computer network and access various services and information resources such as bulletin board systems, downloadable files and programs, news articles, chat rooms, and electronic mail services. The term "online service" was also used in references to these dial-up services. The traditional dial-up online service differed from the modern Internet service provider in that they provided a large degree of content that was only accessible by those who subscribed to the online service, while ISP mostly serves to provide access to the Internet and generally provides little if any exclusive content of its own.

In both software and systems engineering, a use case is a structured description of a system’s behavior as it responds to requests from external actors, aiming to achieve a specific goal. The term is also used outside software/systems engineering to describe how something can be used.

In software (and software-based systems) engineering, it is used to define and validate functional requirements. A use case is a list of actions or event steps typically defining the interactions between a role (known in the Unified Modeling Language (UML) as an actor) and a system to achieve a goal. The actor can be a human or another external system. In systems engineering, use cases are used at a higher level than within software engineering, often representing missions or stakeholder goals. The detailed requirements may then be captured in the Systems Modeling Language (SysML) or as contractual statements.

Horde offers applications such as the Horde IMP email client, a groupware package (calendar, notes, tasks, file manager), a wiki and a time and task tracking software.

Wikipedia is a free multilingual wiki-based open-source online encyclopedia edited and maintained by a community of volunteer editors, started on 15 January 2001 as an English-language encyclopedia. Non-English editions followed in the same year: the German and Catalan editions were created on 16 March, the French edition was created on 23 March, and the Swedish edition was created on 23 May. As of December 2025, Wikipedia articles have been created in 358 editions, with 342 currently active and 16 closed. (and 11 moved to Incubator)

The Meta-Wiki language committee manages policies on creating new Wikimedia projects. To be eligible, a language must have a valid ISO 639 code, be "sufficiently unique", and have a "sufficient number of fluent users".

In the context of video game design, a tutorial is any tool that teaches player or non-player characters the rules, control interface, and mechanics of the game. Some tutorials are integrated into the game, while others are completely separate and optional. Games can have both of these at once, offering a basic mandatory tutorial and optional advanced training. Tutorials have become increasingly common due to the decline of printed video game manuals as a result of cost cutting and digital distribution. Tutorials can be important since they are a player's first impression of a game, and an overly tedious tutorial or one that does not allow for player freedom can negatively affect their view of a game. However, the lack of a tutorial can also harm a game by causing the player to become frustrated, since they cannot figure out essential game mechanics.

The Mangal (Pashto: منګل) are a tribe of the Pashtun people residing in eastern Paktia and adjacent Khost provinces of Afghanistan, and in the town of Tari Mangal, district Kurram, Pirdil Khel, Fatima Khel and Surrani of Bannu Pakistan. Their land constitutes the northeastern part of the Loya Paktia (Greater Paktia) region. The Mangals descend from Karlani Pashtun lineage.Mangals have resisted the various militant groups in the region and other external infiltrators, nevertheless they have remained neutral in respect of recent conflicts. The majority of Mangals are spread across Afghanistan who among other Afghans have been attached to professions such as politicians, military commanders, teachers and scholars specializing in Pashto literature. The Mangal leaders are most recognized for settling tribal disputes and have established an unwritten code known as nerkh, which the Pashtun tribes still use as a tool to resolve conflict among each other. A small number of Mangals residing in the present day lakki marwat District around 1500 AD along with the Honi tribe. Most of these Mangals live as independent in lakki marwat (kpk) and in Kurma Pakistan which borders the Mangal province of Paktia in Afghanistan.

Mangal tribe is also found in Pakistan's Khyber-Pakhtunkhwa province mainly in area of Thall Valley and also in District Hangu and Orakzai Agency of FATA.A large group of Mangal's are living in the valley of kurram agency's areas such as Tari Mangal, Kutri Mangal, Gobazana, Haqdara, Gidu, Sursurang, Piwar tangi and Shalawzan Tangi.Mangal tribe also found in Qematay Mangal nearer to Tari Mangal on Afghanistan side. Mangals Of Tari Mangal and Mangals of Qematay Mangal are relatives of each other. These Mangals on both sides of the border between Pakistan and Afghanistan are called the saver of the border. Tari Mangal, Qematay, Kutri, Gidu and Shalawzan are popular for tourism as thousands of people from different parts of Pakistan have been visiting these zones on special occasions. Almost 70% to 75% Mangal are live in Afghanistan side and 20% to 25% live in Pakistan side.

Lawrence Mark Sanger (/ˈsæŋər/ ; born July 16, 1968) is an American Internet project developer and philosopher who co-founded Wikipedia, along with Jimmy Wales. Sanger coined the name Wikipedia and provided initial drafts for many of its early guidelines, including the "Neutral point of view" and "Ignore all rules" policies. Prior to Wikipedia, he was the editor-in-chief of Nupedia, another online encyclopedia and the predecessor of Wikipedia. He later worked on other encyclopedic projects, including Encyclopedia of Earth, Citizendium, and Everipedia, and advised the nonprofit American political encyclopedia Ballotpedia. Sanger's other interests include theology and philosophy such as epistemology, early modern philosophy, and ethics. He taught philosophy at Ohio State University.

While in college, Sanger began using the Internet for educational purposes and joined the online encyclopedia Nupedia as editor-in-chief in 2000. Disappointed with the slow progress of Nupedia, Sanger proposed using a wiki to solicit and receive articles to put through Nupedia's peer-review process; this change led to the development and launch of Wikipedia in 2001. Sanger continued to serve as Nupedia's editor-in-chief and as an active contributor to Wikipedia in its first year, but he was laid off and left the project in March 2002. Sanger's status as a co-founder of Wikipedia has been questioned by Wales, but is generally accepted.

Wikimedia Commons, a.k.a. Wikicommons, or simply Commons, is a wiki-based media repository of free-to-use images, sounds, videos and other media. It is a project of the Wikimedia Foundation.

Files from Wikimedia Commons can be used across all of the Wikimedia projects in all languages, including Wikipedia, Wikivoyage, Wikisource, Wikiquote, Wiktionary, Wikinews, Wikibooks and Wikispecies, and can also be downloaded for offsite use. As of November 2025, the repository contains over 130 million free-to-use media files, managed and editable by registered volunteers.

wikiHow is an online wiki-style publication featuring informational articles and quizzes on a variety of topics. Founded in 2005 by Internet entrepreneur Jack Herrick, its aim is to create an extensive database of instructional content, using the wiki model of open collaboration to allow users to add, create, and modify content. It is a hybrid organization, a for-profit company run for a social mission. wikiHow uses a forked version of the free and open-source MediaWiki software; these modifications made by wikiHow were freely available to the general public via a self-serve download site from 2010 to late 2020, when wikiHow chose to discontinue the self-serve portal, citing vague "DoS attacks", as well as noting that publishing the source code is "not part of our core mission".

In February 2005, wikiHow had over 35.5 million unique visitors. As of December 2021, wikiHow contains more than 235,000 how-to articles and over 2.5 million registered users.

The WikiWikiWeb is the first wiki, or user-editable website. It was launched on 25 March 1995 by programmer Ward Cunningham and has been a read-only archive since 2015. The name WikiWikiWeb originally also applied to the wiki software that operated the website, which was later renamed to "WikiBase".

A lightweight markup language (LML), also termed a simple or humane markup language, is a markup language with simple, unobtrusive syntax. It is designed to be easy to write using any generic text editor and easy to read in its raw form. Lightweight markup languages are used in applications where it may be necessary to read the raw document as well as the final rendered output.

For instance, a person downloading a software library might prefer to read the documentation in a text editor rather than a web browser. Another application for such languages is to provide for data entry in web-based publishing, such as blogs and wikis, where the input interface is a simple text box. The server software then converts the input into a common document markup language like HTML.

Heinrich Magnus Manske (born 24 May 1974) is a German biochemist who is a researcher on malaria. He is a senior staff scientist at the Wellcome Sanger Institute in Cambridge, UK and a software developer of one of the first versions of the MediaWiki software, which powers Wikipedia and a number of other wiki-based websites.
