Wiki: Pedia

<p>A wiki is a web platform that enables multiple users to collaboratively create, edit, and arrange content through a browser. Wikis prioritize ease of use and openness: pages can be added or changed without technical expertise, and most track every edit so changes can be reviewed or undone. Main features - **Collaborative editing:** Multiple people can edit the same pages, occasionally concurrently. - **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:** Talk or discussion pages let contributors debate edits and organization. Frequent uses - Crowd-sourced knowledge resources (e.g., Wikipedia) - Project documentation and internal company knowledge repositories - Group writing and collaborative note-taking - Educational and classroom projects Benefits - **Fast collaboration:** Multiple people can add and refine content quickly. - **Openness:** Edit histories and talk pages reveal how content decisions were made. - **Expandable:** They scale organically as users add more pages and topics. Limitations - **Vandalism and false information:** Open editing may allow intentional or accidental inaccuracies. - **Inconsistent quality:** Content quality may vary widely between pages. - **Organizational issues:** Lack of structure or rules can lead to disorganization and conflicts.
