Which of the following is NOT a feature of the TCP protocol?
  1. It determines a network’s hardware address from its IP address.
  2. It assures reliable delivery.
  3. It is connection oriented.
  4. It uses sockets and ports to exchange data between applications.
Explanation
Answer: A - TCP does not determine a network’s hardware address from its IP address. Rather, ARP does this.

Key Takeaway: TCP (transmission control protocol) is a connection-oriented protocol for packet delivery. It uses sockets and ports to exchange data between applications. Ports provide a specific and universal location for message delivery, while sockets use the host IP address, port number, and the type of service (TCP or UDP) to create a reliable connection.
