A wiki and a blog are both types of websites that can be used to share information and communicate with others, but they have some key differences.

  1. Purpose: A wiki is designed to be a collaborative knowledge base that can be edited and updated by multiple users. It is often used as a reference tool or resource for information on a specific topic. A blog, on the other hand, is typically used as a platform for an individual or organization to share their thoughts, opinions, or updates in a more informal and personal way.

  2. Content: Wiki articles are typically more objective and fact-based, and are meant to provide comprehensive and accurate information on a specific topic. Blog posts, on the other hand, are often more personal and opinion-based, and may cover a wide range of topics.

  3. Editing: Wikis are designed to be collaborative, so multiple users can edit and update the content. Blogs are usually edited and updated by a single author or a small group of authors.

  4. Structure: Wikis are often organized into categories and subcategories, and may have a hierarchical structure with links between related articles. Blogs are usually organized chronologically, with the most recent posts appearing at the top.

Overall, the main difference between a wiki and a blog is their purpose and the type of content they contain. Wikis are meant to be comprehensive and objective resources, while blogs are more personal and opinion-based platforms for sharing information and updates.
