Explanation:
Detailed explanation-1: -TCP uses a three-way handshake to establish a reliable connection. The connection is full duplex, and both sides synchronize (SYN) and acknowledge (ACK) each other. The exchange of these four flags is performed in three steps-SYN, SYN-ACK, and ACK-as shown in Figure 3.8.
Detailed explanation-2: -UDP is often described as connectionless or “best-effort delivery” because it does not establish a connection before sending, it does not sequence packets before sending, and it does not provide error control through retransmission.
Detailed explanation-3: -What is the purpose of the checksum TCP field? It allows the receiving node to determine whether the TCP segment became corrupted during transmission.
