What is a 'wiki'?

A wiki is fundamentally defined as a collaborative web page designed to allow multiple users to create, edit, and manage content collectively. This collaborative aspect empowers groups to contribute knowledge, share information, and develop projects in a cohesive manner. Wikis are built on the idea of collective intelligence, where users can continuously enhance and refine content, often resulting in a significant repository of information that evolves over time.

The interactive nature of wikis encourages participation from users with diverse backgrounds, enabling the integration of various perspectives and expertise into the content. This enables communities to come together to build a platform of shared knowledge, where any user can participate in modifying the pages.

In contrast to the other options, a single-author blog focuses on the perspective and content of one individual, lacking the collaborative feature found in wikis. A social media platform centers on networking and interaction between users, typically in a more immediate and informal context rather than the structured content creation characteristic of wikis. An online forum facilitates discussions but does not have the same emphasis on collaborative content creation and editing as wikis do.
