Wiki: Pedia

<p>Wikis are websites built for collaborative authoring, allowing numerous contributors to add, edit, and structure content online. Wikis prioritize ease of use and openness: pages can be added or changed without technical expertise, and most track every edit so changes can be reviewed or undone. Main features - **Collaborative editing:** Several contributors can edit pages, sometimes at the same time. - **Edit history:** Every modification is recorded with a timestamp and the editor’s identity or IP address. - **Interlinking:** It’s easy to create links between pages, forming an interconnected knowledge base. - **Lightweight markup:** Simple markup languages (such as WikiText or Markdown) are used to format pages. - **Permission settings:** Wikis may allow public editing or restrict changes to registered or authorized users. - **Discussion pages:** Talk or discussion pages let contributors debate edits and organization. Frequent uses - Community-driven knowledge bases (for example, Wikipedia) - Project documentation and internal company knowledge repositories - Group writing and collaborative note-taking - Classroom and educational projects Benefits - **Fast collaboration:** Multiple people can add and refine content quickly. - **Openness:** Visibility into edits and discussions shows how decisions were reached. - **Expandable:** Wikis expand easily as contributors add and organize content. Limitations - **Vandalism and false information:** Public editing can lead to vandalism or incorrect information. - **Inconsistent quality:** Entries may vary in accuracy, style, and completeness. - **Organizational issues:** Without clear governance, content may become fragmented or disputed.
