10. TCP and UDP. a. Why is packet switching used in the Internet rather than circuit switching? Describe the advantages and disadvantages of each. b. Provide and explain 2 reasons why we would use UDP instead of TCP. c. Explain the process of a DNS lookup for a host in a remote domain. How do reverse DNS lookups (IP address to name) work? d. What are persistent connections? What is connection pipelining? Why do we have both? e. We say that TCP “does not preserve message boundaries” while UDP “does preserve “message boundaries”. What is meant by this and what are the implications for our applications?
