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. Key features - **Collaborative editing:** Multiple people can edit the same pages, occasionally concurrently. - **Edit history:** Each change is logged with a time and the editor’s name or IP. - **Interlinking:** Creating links among pages is straightforward, which helps interconnect content. - **Lightweight markup:** Formatting is usually handled by lightweight markup languages (e.g., WikiText or Markdown). - **Permission settings:** Some wikis are open to anyone; others limit edits to registered users or specific groups. - **Discussion pages:** Talk or discussion pages let contributors debate edits and organization. Common uses - Crowd-sourced knowledge resources (e.g., Wikipedia) - Project documentation and internal company knowledge repositories - Cooperative writing and shared notes - School and instructional projects Advantages - **Fast collaboration:** Contributors can rapidly create and improve content. - **Openness:** Visibility into edits and discussions shows how decisions were reached. - **Expandable:** They scale organically as users add more pages and topics. Limitations - **Vandalism and false information:** Open contribution can result in deliberate or accidental misinformation. - **Inconsistent quality:** Entries may vary in accuracy, style, and completeness. - **Organizational issues:** Without clear governance, content may become fragmented or disputed. Example - **Wikipedia** — the largest example, maintained by the Wikimedia Foundation and contributed to by volunteers worldwide.</p>
