The network topology describes the specific physical arrangement of the
elements of a network.
In widespread use are:
Common types of network topologies are illustrated here.
- 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.
