Basic knowledge related to the communication and computer networks. Connections in network surrounding. Students should acquire the basic function of network connections and layered function distribution.

Students would acquire the basic principles of communication networks. It is intended to clarify the fundamental problems at network layers. The subject is organized as a sequel of engineering problems that should be solved at the various levels of communication link. An engineering compromise would be explained, as a solution that satisfy both the final user, and the requirements considering the available resources.
