description: An Application Protocol Data Unit (APDU) is a standardized message format used for exchanging information between network components, particularly in the realm of telecommunications. It plays a crucial role in remote provisioning and authentication processes for embedded SIM cards (UICC and USIM). APDU defines the structure and content of messages exchanged during these operations.
explanation: The description explicitly mentions APDU's use in 'remote provisioning and authentication,' which are core functionalities within telecommunications protocols. Its standardized format and role in data exchange between network components further solidify its classification as a protocol.
