This
course presents a unified overview of the broad field of data and computer
communications emphasizing its basic principles and topics of fundamental
importance. The student is introduced to the basic OSI and TCP/IP protocol
architectures along with the concept of protocol layering to elucidate the
vertical and horizontal interactions between protocols. Topics such as WAN and LAN are then covered
in the context of the nodes that are connected either directly or through a
multiple access network. Emphasis is
laid on the concepts of error control, synchronization, switching and
multiplexing techniques as well as data security.
