In TCP/IP-based data communication, which header will be added to the data that passes through the transport layer?
Answer:
Explanation:
In TCP/IP-based data communication, when data passes through the transport layer, either a TCP (Transmission Control Protocol) header or a UDP (User Datagram Protocol) header will be added to the data, depending on the protocol used.
TCP header: Used for connection-oriented, reliable communication. The header contains information such as source and destination port numbers, sequence numbers, acknowledgment numbers, and control flags.
UDP header: Used for connectionless, less reliable communication. The header is simpler and includes source and destination port numbers, length of the datagram, and a checksum for error checking.
