A network map is a visual representation of devices in the network, their interconnections, and the transport layers that provide network services. Not only should it include switches, routers, firewalls, virtual LANs (VLANs), and access points, but it should also include hosts on the network.

A network map is a visualization of devices on a network, their inter-relationships, and the transport layers providing network services. Practically, a Network Map is one tool to provide network users, managers and administrators, and IT personnel with a better understanding of network performance, especially concerning data bottlenecks and associated root cause analysis.

A network map makes viewing the entire network and related information as simple as browsing an actual online map. Every device connected to the network is displayed in an easy-to-understand graphical representation using network mapping software.

A network map is simply a document that helps IT better manage the network. Maps can function as a visual topology of all your network devices, a geographic map of where devices are located, or a dashboard of network performance.
