Discussion
Which of the following is true concerning the standard network protocol for connecting a client to a Web or database server via the Internet?
Answer: B
Correct answer: Both TCP and IP are needed.
The two do different halves of the job and neither replaces the other. IP addresses and routes each packet to the right machine; TCP reassembles the packets in order, detects loss and retransmits. A reliable connection needs both, which is why the pair is always named together.
