# 1.3. Terms to Understand

Before understanding RHN Satellite Server, it is important to become familiar with the following Red Hat Network terms:

- Channel — A channel is a list of software packages. There are two types of channels: base channels and child channels. A base channel consists of a list of packages based on a specific architecture and Red Hat release. A child channel is a channel associated with a base channel that contains extra packages.

- Organization Administrator — An Organization Administrator is a user role with the highest level of control over an organization's Red Hat Network account. Members of this role can add other users, systems, and system groups to the organization as well as remove them. A Red Hat Network organization must have at least one Organization Administrator.

- INCLUDE — A Channel Administrator is a user role with full access to channel management capabilities. Users with this role are capable of creating channels, assigning packages to channels, cloning channels, and deleting channels. This role can be assigned by an Organization Administrator through the Users tab of the RHN website.

- Red Hat Update Agent — The Red Hat Update Agent is the Red Hat Network client application (`up2date`) that allows users to retrieve and install new or updated packages for the client system on which the application is run.

- Traceback — A traceback is a detailed description of "what went wrong" that is useful for troubleshooting the RHN Satellite Server. Tracebacks are automatically generated when a critical error occurs and are mailed to the individual(s) designated in the RHN Satellite Server's configuration file.

For more detailed explanations of these terms and others, refer to the Red Hat Network Reference Guide.
