This module provides an in-depth study of network components, and their functions and placement in Metropolitan Local Area Networks (MANs) and Wide Area Networks (WANs). Students will be introduced to issues behind the linking of networks, network communication / routing protocols, network hardware, network software / operating systems, and the integration of disparate networks. Routing protocols includes, but not limited to, Routing Information Protocol (RIP), Border Gateway Protocol (BGP), Interior Gateway Routing Protocol (IGRP), Enhanced Interior Gateway Routing Protocol (EIGRP), and Exterior Gateway Routing Protocol (EGRP).
