Basic Terminology

vBulletin 5 Connect introduces some new concepts on how content is contained in the system. In previous versions, each content type was separate with its own programming, database tables and functionality. In vBulletin 5 Connect, we've eliminated the redundancy this caused and that has required some new terms to be introduced.

This refers to your vBulletin 5 Connect installation including all of its content, pages and users.
Forum Root
This is the directory that you installed vBulletin 5 Connect in. In most cases this with by public_html.
Presentation Layer

What are Channels?
Channels are Nodes that can contain other Nodes. In vBulletin 5, Channels include: Forums, Articles, Blogs, Social Groups, Private Messages, Visitor Messages, User Albums, and Flagged (reported) Content. Additional Channels may be added in the future. Some channels can be maintained with the Channel Management (formerly Forum Management) tools in the Admin CP. Others are hidden from view and maintained by the individual users.
What are Nodes?
Nodes are any content within vBulletin 5. They can be discussions, photos, links or channels among other content types. Generally speaking you will refer to nodes by their content type.
What are Content Types?
Content Types allow your users to control how their contributions are presented to others. These can be Photo Galleries, Links, Polls, or Text. Each content type can be used to create topics on the site. As the Administrator, you control the content types that are available to users through permissions.

Some channels can be made private. A Channel User is an individual that has permission to access a specific channel. Social Groups are an example of channels that have users.
