A single web site can contain many types of content, such as informational pages, news items, polls, blog posts, academic programs listings, etc. In Drupal, each item of content is called a node, and each node belongs to a single content type, which defines various default settings for nodes of that type, such as whether the node is published automatically and whether comments are permitted. (Note that in previous versions of Drupal, content types were known as node types.)
Current content types
Articles are generally used for information that is updated more frequently and often cross-referenced and categorized (such as news items or resources). By default, Articles are sorted with the most recent post at the top.
The Basic page content type is used for static content that can (but are not required to) be linked into the main navigation bar. This is one of the most "basic" content types and can be very flexible.
The Person page content type is specifically for person profiles. This can include not only students, staff, and faculty, but also individuals who are the focus of events or news articles in your site, thus allowing you to link their person page to the related content.
The Event page content type is a simple variation on an Event notice. A event listing will dynamically appear in your site if you decide to create any Event pages. Person pages can be attached to this content type. This is a simple event listing solution so, if you need something more robust, users are welcome to include the campus' Trumba system instead.
Image gallery page
The Image gallery content type will allow you to display collections and albums of images.
