The meaning of hierarchy in the tree topology

Network Topology Tree (Tree) network topology is referred to as a multilevel network topology. This topology is typically used for interconnection between the central with a different hierarchy. For the lower hierarchy depicted in locations with low and growing up had a higher hierarchy. This type of network topology suitable for use on a computer network system.

In tree networks, there are several levels of nodes (node​​). Central or higher level node, another node can set a lower level. Data sent to the central node first. For example to move from computer to the komputer node node-3-7 as well as in the figure, the data must pass through node-3, 5 and node-6 before ending at the node-7.

The excellence of tree network  model like this is, can the formation of a group that required at all times. For example, companies can form a group consisting of terminal accounts, as well as in the other group formed for the sale terminals. The weakness is, if the node that is higher then does not work, then the other group who are below it eventually also became ineffective. The workings of a tree network is relatively slow.
