Wiki: Pedia

<p>A wiki is a web platform that enables multiple users to collaboratively create, edit, and arrange content through a browser. They emphasize simplicity and openness — pages can be created or modified without special technical skills, and most maintain an edit history so revisions can be reviewed or reverted. Common features - **Collaborative editing:** Numerous contributors can work on pages, sometimes simultaneously. - **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:** Dedicated discussion pages enable contributors to coordinate and discuss content. Typical 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 Advantages - **Fast collaboration:** Many people can collaborate and iterate quickly on 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:** Public editing can lead to vandalism or incorrect information. - **Inconsistent quality:** Articles can differ greatly in depth, tone, and reliability. - **Organizational issues:** Without clear governance, content may become fragmented or disputed.
