The interconnections of nodes in a communications network. Nodes are wired together in a star, bus or ring architecture. Ethernet uses a star configuration, although earlier Ethernets used a bus.

Network topology is the "shape" of a network of biological interactions and shows how the nodes — the parts of the network where elements interact — are connected to each other. Common ...

the whole network fails if the switch fails as no node can communicate a wired star topology requires plenty of cable - in a large network this can be expensive Star topologies tend to be found in ...

A logical topology is how devices appear connected to the user. A physical topology is how they are actually interconnected with wires and cables. For example, in a shared Ethernet network that ...
