What is the difference between the TCP and UDP protocols?
The correct answer is B. TCP has a 20-byte minimal header size, and UDP has an 8-byte header size.. TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are both transport layer protocols. TCP has a minimum header size of 20 bytes, which includes fields for sequencing, acknowledgments, and flow control, ensuring reliable communication. UDP has a smaller 8-byte h

Explanation
TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are both transport layer protocols. TCP has a minimum header size of 20 bytes, which includes fields for sequencing, acknowledgments, and flow control, ensuring reliable communication. UDP has a smaller 8-byte header, making it more efficient for time-sensitive applications like streaming and VoIP, but it does not guarantee delivery or ordering.
