a) Why is the terminology of client and server is still being used in peer-to-peer (p2p) applications? Rectangular Snip b) Describe how web caching can reduce delay in receiving a requested object. Will Web caching reduce the delay for all objects requested by a user or for only some of the objects? Explain why c) Explain clearly the issues related to non-persistent HTTP application protocol and explain how persistent HTTP application protocol overcomes the issues effectively. d) Suppose Ironman with a web-based email account (such as Hotmail or Gmail), sends a message to Spiderman, who access his mail from his e-mail server using IMAP. Discuss how the message gets from Ironman's host to Spiderman's host with the help of a diagram. Be sure to list the series of application layer protocols that are used to move the message between the two hosts. a) Why is the terminology of client and server is still being used in peer-to-peer (p2p) applications?
