Wiki: Pedia

<p>A wiki is a website designed for collaborative editing, letting many people create, update, and organize content directly in a web browser. 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:** Each change is logged with a time and the editor’s name or IP. - **Interlinking:** It’s easy to create links between pages, forming an interconnected knowledge base. - **Lightweight markup:** Formatting is usually handled by lightweight markup languages (e.g., WikiText or Markdown). - **Permission settings:** Access controls vary — from fully open editing to permissions for certain users or groups. - **Discussion pages:** Separate talk pages allow contributors to discuss edits and structure. Frequent uses - Community-driven knowledge bases (for example, Wikipedia) - Project documentation and internal company knowledge repositories - Collaborative writing and shared note-taking - School and instructional projects Advantages - **Fast collaboration:** Many people can collaborate and iterate quickly on content. - **Openness:** Visibility into edits and discussions shows how decisions were reached. - **Expandable:** Wikis expand easily as contributors add and organize content. Drawbacks - **Vandalism and false information:** Public editing can lead to vandalism or incorrect information. - **Inconsistent quality:** Articles can differ greatly in depth, tone, and reliability. - **Organizational issues:** Lack of structure or rules can lead to disorganization and conflicts. Example - **Wikipedia** — the best-known wiki, run by the Wikimedia Foundation and built by volunteer contributors worldwide.</p>
