Frame, packet, segment, and lastly data shows the correct order of PDU de-encapsulation when a device receives messages from a network.
What is a PDU? corruption of a frame during transmission data reassembled at the destination retransmitted packets due to lost communication a layer specific encapsulation
Frame Header - Network Header - Transport Header - Data - Frame Trailer
The PDU at the Network layer is referred to as a packet. A PDU at the Data Link Layer is referred to as a frame.

Datagrams TCP/IP layer 4 PDU's are called segments...
The PDU (protocol data unit) @ transport layer (e.g. TCP or UDP) is called as 'segment' .

LLC in LAN Technologies (4) LLC protocol - HDLC protocol Type 3 of operation - each transmitted PDU is acknowledged: - a new unnumbered PDU is defined: Acknowledge Connectionless (AC) PDU - user data are sent in AC command PDUs an must be ack using an AC response PDU. - to guard against the lost PDUs, a 1-bit sequence number is used: the sender alternates 0 and 1… - only one PDU in each direction may be outstanding at any time
