(a) Suppose a student at the University library is connecting a laptop for the first time to a Local Area Network (LAN) via an Ethernet cable. The student opens a web browser on the laptop and types in the URL of a web page (e.g., http://www.reading.ac.uk). Describe all the network protocols (at all layers) and packet multiplexing/demultiplexing the student's device engages in order to connect to the network and to deliver the webpage to the browser briefly in order of their usage. (10 marks) (b) Briefly explain Dynamic Host Configuration Protocol (DHCP), and list the information it provides? (5 marks) (c) IPv4 has been used for many years successfully, but it is currently being updated to IP version 6 (IPv6). Describe why this update is needed. What are the benefits of IPv6 offered above IPv4? (5 marks) Datagrams travel between hosts over a series of communication links. Considering the link and transport layers, answer the following: (a) What is a CRC code? What purpose does it serve? Compute the CRC bits defined by the generator 1001 and the data bit string 101111. (8 marks) (b) Describe six primary differences between TCP and UDP. Describe the primary elements in the headers of TCP and UDP. Also provide an application example for each protocol.
