Frames

B.

Datagrams

C.

Segments

D.

Packets.

UDP (User Datagram Protocol) is a connectionless transport layer protocol that operates on top of the IP (Internet Protocol). It provides a fast and efficient way to send datagrams from one host to another without any connection setup or verification process.

Out of the given options, only "Datagrams" operate within the UDP protocol. A datagram is a self-contained packet of data that is transmitted over a network. It contains information about the source and destination hosts, as well as the data being transmitted.

Frames, Segments, and Packets are all terms that refer to different layers of the network stack and can be used with different protocols.

Frames refer to the units of data that are transmitted at the physical layer of the network stack. They are used by protocols such as Ethernet to transmit data over a physical network.

Segments refer to the units of data that are transmitted at the transport layer of the network stack. They are used by protocols such as TCP (Transmission Control Protocol) to ensure reliable delivery of data between hosts.

Packets refer to the units of data that are transmitted at the network layer of the network stack. They are used by protocols such as IP to route data between hosts on different networks.

In summary, only "Datagrams" operate within the UDP protocol. The other options refer to different layers of the network stack and can be used with different protocols.
