5.2.2 Network Topologies
In the case of 10Base-T, or 100BaseTX several stations (nodes) are connected
using a star topology according to the 10Base-T ETHERNET Standard.
Therefore, this manual only deals with the star topology, and the tree topology
for larger networks in more detail.
Star Topology
A star topology consists of a network in which all nodes are connected to a
central point via individual cables.
Fig. 5-4: Star Topology
A star topology offers the advantage of allowing the extension of an existing
network. Stations can be added or removed without network interruption.
Moreover, in the event of a defective cable, only the network segment and the
node connected to this segment is impaired. This considerably increases the
fail-safe of the entire network.
Tree Topology
The tree topology combines characteristics of linear bus and star topologies.
It consists of groups of star-configured workstations connected to a linear bus
backbone cable. Tree topologies allow for the expansion of an existing
network, and enables schools, etc. to configure a network to meet their needs.
