Acquiring basic knowledge about standard methods of data transfer and linking the theoretical background in this field with specific solutions applied in practice.

Good knowledge of the principles of communication protocol functioning by OSI reference mode, as well as the practical version of protocols implemented in LAN and WAN networks, with an emphasis on the TCP/IP protocols (Internet).
