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. Simplicity and openness are central to wikis: anyone can often add or change pages without technical knowledge, and edits are usually logged for review or rollback. Main features - **Collaborative editing:** Multiple people can edit the same pages, occasionally concurrently. - **Edit history:** Every modification is recorded with a timestamp and the editor’s identity or IP address. - **Interlinking:** Links between pages are simple to create, helping build connected content. - **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:** Separate talk pages allow contributors to discuss edits and structure. Typical uses - Community knowledge bases such as Wikipedia - Internal documentation and company knowledge bases - Collaborative writing and shared note-taking - School and instructional projects Pros - **Fast collaboration:** Multiple people can add and refine content quickly. - **Openness:** Edit histories and talk pages reveal how content decisions were made. - **Expandable:** Wikis can grow naturally as contributors add new topics. Cons - **Vandalism and false information:** Open editing may allow intentional or accidental inaccuracies. - **Inconsistent quality:** Content quality may vary widely between pages. - **Organizational issues:** Poor coordination or governance can cause content fragmentation and disputes. Example - **Wikipedia** — the largest example, maintained by the Wikimedia Foundation and contributed to by volunteers worldwide.</p>
