What is the proper term to refer to a single unit of IP data?

A.
IP segment.

B.
IP datagram.

C.
IP frame.

D.
IP fragment.

Explanation:
The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying
datagrams across network boundaries. The Internet Protocol is responsible for addressing hosts and for routing
datagrams (packets) from a source host to a destination host across one or more IP networks.
Incorrect Answers:
A: There is nothing called IP segment within the OSI model. The TCP protocol uses segments, while the IP
protocol uses datagrams.
C: The network layer (layer 2) of the OSI model handles data link frames, but there are no IP frames in the OSI
model. IP datagrams are the network layer (layer 3).
D: There is nothing called IP fragment within the OSI model.
