A wide-area network (WAN) is a data communications network that connects user networks over a large geographical area. WANs have several important characteristics that distinguish them from LANs. In this module is about providing an overview of WAN technologies and protocols.
This module is about understanding the physical layer components of a router. This knowledge builds a foundation for other information and skills that are needed to configure routers and manage routed networks.
