Network cards & adapters
A network map is a graphical representation of a computer network. It shows the network nodes, usually represented as circles, and the connections between them, usually represented as lines. Network maps can be very simple, showing only a few nodes and connections, or they can be very complex, showing hundreds or even thousands of nodes and connections. In addition to the structure of a network, network maps can also show the traffic levels on each connection. This information can be useful for diagnosing problems with the network or identifying bottlenecks that need to be addressed.
