The aim is to introduce students to information systems functioning over a network. The course starts with the basics of communication protocols and the OSI reference model. Logical design issues of each of the seven layers. Issues such as routing and connection management, data compression principles and techniques are studied. Operating system communication interfaces are presented (e.g. Unix and Windows sockets). Comparison and contrasts between the OSI and TCP/IP model. Also discusses the various Network topologies and importance of Storage Area Networks in today\\\'s computing environments. |
