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' .

Frame relay and PPP is used with WAN encapsulation. Frame Relay most closely compares to the OSI data link layer (Layer 2). If you remember that the word "frame" describes the data link layer protocol data unit (PDU), it will be easy to remember that Frame Relay relates to OSI Layer 2. Like other data-link protocols, Frame Relay can be used to deliver packets (Layer 3 PDUs) between routers.
