What is Wiki?

Meaning & Definition


A wiki is a collaborative website or online platform that allows multiple users to create, edit, and organize content in a cooperative manner. Wikis are designed to enable the creation of a knowledge base or database of information on a specific topic, subject, or project. The term “wiki” is derived from the Hawaiian word for “quick.”

Key characteristics and features of wikis include:

  • Collaborative Editing

Wikis enable multiple users to contribute to and edit the content, making it a collaborative and dynamic platform. Users can add, revise, or delete information.

  • Version History

Wikis maintain a history of edits, allowing users to view and revert to previous versions of the content. This feature helps in tracking changes and resolving disputes.

  • Hyperlinks

Wikis often use hyperlinks to connect pages and topics, making it easy to navigate between related articles.

  • User Contributions

Each user’s contributions are typically attributed to their username, fostering accountability and recognition for their work.

  • Structured Content
