Goals:  This class will cover necessary theoretical foundation and the protocol and architecture of modern computer communication networks, including LANs, MANS, WANs and other packet switched networks. Particular attention will be given to Internet architectures and protocols. It is designed to introduce the basic concepts in data communications, computer networks and the OSI standard to senior-level students in electrical and computer engineering.
