negotiated and used for DICOM message
exchange. It consists of the
Presentation Context ID (a temporary
number, assigned for the duration of an
Association), and the Abstract

Means of making sure both sides of
communication agree what they're going
to be doing and how they're going to
encode the data.

Private Data Element: Additional Data Element, defined by an implementor, to communicate information that is not contained in Standard Data Elements. Private Data elements have odd Group Numbers.
Profile: A set of operations or service to be performed. Similar to an "application profile," but more than just the application. It includes: the application; the application's interface to the network; a set of options. A profile forms the basis for judging DICOM conformance. A product doesn't conform to the DICOM standard, but rather to one of the available DICOM profiles.
Protocol: Data format; the format data must be in for peer-to-peer communication.
Protocol data unit: PDU. The block used to encode data that passes over an association.
