Network Topology

The network topology describes the specific physical arrangement of the elements of a network.

In widespread use are:

  • Broadcast networks: a single communication channel is shared by all connected network elements. And thus a packet sent by any station is received by all the others.
  • Point-to-point networks: there exist many connections between individual pairs of stations. Eventually a packet travels from source to destination through one or more intermediate stations.
Common types of network topologies are illustrated here.
