Final answer:
To provide reliable end-to-end communication, the Transmission Control Protocol (TCP) should be used because it ensures the accurate and orderly delivery of data packets.
Step-by-step explanation:
If you want to provide reliable end-to-end communication over the Internet, the correct protocol to use is the Transmission Control Protocol (TCP). TCP is designed to deliver data packets accurately and in the same order they were sent, ensuring information integrity and order. In contrast to TCP, other protocols like the User Datagram Protocol (UDP) offer a faster, but less reliable, method of communication. UDP does not guarantee packet order or even delivery. The Domain Name System (DNS) resolves domain names to IP addresses and does not itself ensure reliable communication. The Internet Protocol (IP) is responsible for addressing and routing packets across networks but doesn't offer reliability features inherent to TCP.
