Terminology
AUP documents are similar to and often doing the same job as a document labelled Terms of Service for example, as used by Google Gmail and Yahoo!, although not in every instance, as in the case of IBM.com where the Terms of Use is about the way in which IBM presents the site for you, and how they will interact with you using the site with little to no instruction as to how you, the user, will use the site.
In some cases, AUP documents are named Internet and E-mail policy, Internet AUP, or Network AUP and also Acceptable IT Use Policy. These documents, even though named differently, largely provide policy statements as to what behaviour is acceptable from users of the local network/Internet connected via the local network.
