1) List the two major Transport layer protocols and describe what they do. 10) If I use FTP (File Transfer Protocol) to download a copy of the Windows 10 operating system, TCP would be the best transport layer protocol choice because it breaks this large file into smaller packets and makes sure all are accurately downloaded and assembled in the right order. Give an example of the kind of data that is best sent using UDP. Explain why UDP is the better protocol for this kind of traffic. 2) Explain why error correction is more important at the Transport layer than at the Data Link layer. 3) The Protocol Data Unit at the Data Link layer is the Frame. The PDU at the Network layer is the Packet. List the PDUs for TCP and UDP at the Transport layer. 4) Explain how and why we use sequence numbers in a TCP segment. 5) Consider two computers talking to each other, using TCP to send a series of segments. What happens if one computer sends a segment that gets lost? 6) List the port address for each of the following protocols: HTTP FTP SMTP Quote of the Day 7) List the three ranges of ports and explain how they differ. 8) Explain the difference between stop-and-wait flow control and sliding window flow control.
