Drupal: An open source Content Management System. A giant database of information that makes up a website and its pages of content. A content management system allows multiple people to log in and edit content, and provides various types of automation.
Content Types: “Container” with various text fields to form nodes. A content type can be a page, a news story, a faculty page or anything else that is needed on a site. All content types have a "Title" field (required) and most have a textarea, usually called "Body." Specialized content types have additional fields.
Views: A programmed display of fields within a particular content type. Or, a list of nodes of a certain type, in a certain order. Often used for lists of content, such as a Directory or a list of Upcoming Events. Biocom will usually deal with creating or altering existing Views. The way to add, change, or remove items on a list is to edit or create each individual node of that content type.
Block: A small chunk of content (not a page or a node). Blocks can be assigned to regions within Drupal. Some blocks are created from scratch (custom blocks). Others are created by a Menu (menu block) or a View (block display from a View). Users with some roles can edit custom blocks.
Regions: Areas within a Drupal theme that content is assigned to. Examples: Header, Footer, Sidebar.
Nodes: When you create a new "page" from a content type, that is a node.
Pages: Pages are usually nodes, but can be a display from a View.
