Question

compare the tcp header and the udp header. list the fields in the tcp header that are not a part of the udp header. give the reason for each missing field

Answer 1

The TCP header contains fields that are not present in the UDP header.

Step-by-step explanation:

The TCP header and UDP header are both part of the transport layer of the TCP/IP protocol suite. The TCP header is larger and more complex than the UDP header. The fields in the TCP header that are not part of the UDP header are:

1. Sequence Number: This field is used to keep track of the order of the packets sent and received. UDP does not require ordered delivery of packets, so it does not include this field.
2. Acknowledgment Number: This field is used to acknowledge received packets in TCP. UDP does not use acknowledgments, so it does not include this field.
3. Window Size: This field is used to control the flow of data in TCP. UDP does not require flow control, so it does not include this field.

These fields are not included in the UDP header because UDP is a connectionless and unreliable protocol, while TCP is a connection-oriented and reliable protocol.
