Wiki: Pedia

<p>A wiki is a web platform that enables multiple users to collaboratively create, edit, and arrange content through a 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:** Numerous contributors can work on pages, sometimes simultaneously. - **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:** Separate talk pages allow contributors to discuss edits and structure. Common uses - Community knowledge bases such as Wikipedia - Project documentation and internal company knowledge repositories - Collaborative writing and shared note-taking - School and instructional projects Benefits - **Fast collaboration:** Contributors can rapidly create and improve content. - **Openness:** Transparency through revision histories and discussions. - **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:** Articles can differ greatly in depth, tone, and reliability. - **Organizational issues:** Poor coordination or governance can cause content fragmentation and disputes.
