Step-by-step explanation:
A web site that allows anyone to add or edit content is called a wiki. This type of site is a collaborative space where users can collectively create and modify content. Unlike a weblog, or blog, which typically shows posts in reverse chronological order and where the blog owner can moderate comments and content, a wiki is designed to be edited by anyone who has access. This is evident in platforms such as Wikipedia, which have extensive content created and edited by users from around the world. A multiuser site may refer to any website that allows multiple users to interact or contribute but does not specifically denote a site where anyone can edit content. A podcast, on the other hand, is a digital audio or video series that users can download and listen to but does not offer the ability for collaborative editing or content creation.
