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. Common features - **Collaborative editing:** Several contributors can edit pages, sometimes at the same time. - **Edit history:** All edits are stored with timestamps and the author’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:** Wikis may allow public editing or restrict changes to registered or authorized users. - **Discussion pages:** Talk or discussion pages let contributors debate edits and organization. Frequent uses - Community-driven knowledge bases (for example, Wikipedia) - Project documentation and internal company knowledge repositories - Group writing and collaborative note-taking - School and instructional projects Pros - **Fast collaboration:** Contributors can rapidly create and improve content. - **Openness:** Visibility into edits and discussions shows how decisions were reached. - **Expandable:** Wikis expand easily as contributors add and organize content. Cons - **Vandalism and false information:** Open contribution can result in deliberate or accidental misinformation. - **Inconsistent quality:** Content quality may vary widely between pages. - **Organizational issues:** Lack of structure or rules can lead to disorganization and conflicts.
