The size of the UDP port field is:Question 9Select one:a.8 bitsb.16 bitsc.32 bitsd.48 bitse.64 bits

Break Down the Problem

1. Identify the question regarding the size of the UDP port field.
2. Analyze the options provided.

Relevant Concepts

1. The User Datagram Protocol (UDP) is part of the Internet Protocol suite.
2. The UDP header includes a port field, which is critical for identifying the sending and receiving applications.

Analysis and Detail

1. The UDP header consists of several fields, including:
   • Source Port (16 bits)
   • Destination Port (16 bits)
2. Therefore, the total size of the UDP port field (for source and destination combined) is $16 + 16 = 32 \text{ bits}$, but since the question asks for the size of the port field specifically, we focus on individual ports, which is 16 bits each.

Verify and Summarize

1. Each port field (source and destination) is 16 bits.
2. Thus, the correct answer is based on the size of a single UDP port.

Final Answer

b. 16 bits
