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. 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. Key features - **Collaborative editing:** Several contributors can edit pages, sometimes at the same time. - **Edit history:** Every modification is recorded with a timestamp and the editor’s identity or IP address. - **Interlinking:** Creating links among pages is straightforward, which helps interconnect content. - **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. Common uses - Community knowledge bases such as Wikipedia - Project documentation and internal company knowledge repositories - Collaborative writing and shared note-taking - Classroom and educational projects Advantages - **Fast collaboration:** Many people can collaborate and iterate quickly on content. - **Openness:** Transparency through revision histories and discussions. - **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:** Poor coordination or governance can cause content fragmentation and disputes.
