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:** 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:** Simple markup languages (such as WikiText or Markdown) are used to format pages. - **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 knowledge bases such as Wikipedia - Internal documentation and company knowledge bases - Collaborative writing and shared note-taking - Educational and classroom 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:** They scale organically as users add more pages and topics. Cons - **Vandalism and false information:** Public editing can lead to vandalism or incorrect information. - **Inconsistent quality:** Content quality may vary widely between pages. - **Organizational issues:** Lack of structure or rules can lead to disorganization and conflicts. Notable example - **Wikipedia** — the best-known wiki, run by the Wikimedia Foundation and built by volunteer contributors worldwide.</p>
