In the context of distributed processing systems, we usually use classifications with respect to THREE basic characteristics – Topology, Protocol, Architecture.
a) With the help of diagrams, explain the THREE basic topologies used in computer networks – bus, ring, and star.

b) Explain the TWO major types of network architecture: Peer-to-peer and client/server.

c) There are several communication protocols designed over the years like Novell’s IPX/SPX and Microsoft’s NetBEUI, but de facto standard protocol nowadays for computer networks is the TCP/IP protocol. It is designed around the client-server model.
Can TCP/IP be used in every one of the architectures mentioned in part a) of the question? Explain your answer.
