Recognize the following logical or physical network topologies
given a schematic diagram or description:
If
computers are connected in a row, along a single cable this is
called a bus topology, if they branch out from a single junction or
hub this is known as a star topology. When computers are connected
to a cable that forms a continuous loop this is called a ring
topology.
Star/hierarchical
|
Star |
Hierarchical or cascading star
|
Computers in a star topology are connected by cables to a hub. In
this topology management of the network is made much easier (such as
adding and removing devices), because of the central point. However
because it is centralized more cable is required.
Because
most star topologies use twisted-pair cables, the initial
installation of star networks is also easier.
If one
computer fails the network will continue to function, but if a hub
fails all computers connected to it will also be affected.
Star
topologies are, or are becoming the topology of choice for networks.
