They have both archive pages (sorted by author, publication date, etc.) and single pages that show a post on its own. Posts always have a publication date, and they are sorted into categories and tags to make them easier for the administrator to manage and for the visitors to locate. If the active theme has support for it, they can also be sorted into different post formats like image, video and quote. A post can be set to sticky to make it appear at the top of the first page of the blog archive, irregardless of its publishing date.
A post is frequently displayed along with the name of the author, the date of publication and any categories and/or tags it is associated with. Unlike pages, they also have the WordPress comment functionality activated as default.
