Which name is assigned to the transport layer PDU?
bits
data
frame
packet
segment
Explanation:
Application data is passed down the protocol stack on its way to be transmitted across the network media. During the process, various protocols add information to it at each level. At each stage of the process, a PDU (protocol data unit) has a different name to reflect its new functions. The PDUs are named according to the protocols of the TCP/IP suite:
Data – The general term for the PDU used at the application layer.
Segment – transport layer PDU
Packet – network layer PDU
Frame – data link layer PDU
Bits – A physical layer PDU used when physically transmitting data over the medium
