Examn questions, jan 2003

Disclaimer: This list is yet to be confirmed!

The book will be available at the examn. You may bring (at most) one sheet of A4-paper for each question!

1. Explain what a protocol is. Use HTTP as an example.
2. Explain those steps a browser (and a webserserver) go through to obtain a webpage from a web address.
3. Explain the purpose of the transport Layer including its relation to the network Layer. Explain the difference between TCP and UDP.
4. Explain the functionality of a sliding window protocol.
5. Explain the principles of congestion control. Use TCP congestion control as an example.
6. Explain the difference between congestion control and flow control.
7. Explain the difference between Link State Routing and Distance Vector Routing. You are welcome to use examples.
8. Explain the individual fields in a TCP segment. Give detailed explanantions for the most important fields.
9. Explain how IPv4 packets may be fragmented during the way through the network. Similarly for IPv6.
10. Explain the difference between symmetric and assymetric encryption. Use PGP as an example.
11. Explain the individual fields in a IPv4 packet. Give a detailed explanation for the most important fields.
12. Explain the difference between an IPv4 packet and an IPv6 packet. Further, explain how to move from IPv4 to IPv6, including what tunneling means.
