A 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 enable schools to configure a network to meet their needs.
HYBRID TOPOLOGY
A hybrid topology is always produced when two different basic network topologies are connected. Two common examples for Hybrid network are: star ring network and star bus network.
MESH TOPOLOGY
A mesh topology can be a full mesh topology or a partially connected mesh topology.
In a full mesh topology, every computer in the network has a connection to each of the other computers in that network. The number of connections in this network can be calculated using the following formula (n is the number of computers in the network): n(n-1)/2
In a partially connected mesh topology, at least two of the computers in the network have connections to multiple other computers in that network. This is a cheaper way to build a network that has some redundancy in the event one of the primary computers or connections in the network were to be down.
