It is the simplest network topology among all topologies. Topology generally determines the shape of the network. In this topology, all computers and networking devices are connected to a single backbone cable. In a home network, this can be such things as printers, a central storage drive, mp3 files, and anything you can think of that can take advantage of the servers capabilities. Distances between nodes, physical interconnections, transmission rates, andor signal types may differ between two networks, yet their topologies may be identical. The following are the different types of network topology. It is topology which governs data flow between respective nodes. A metric space is a set x where we have a notion of distance.
