In hierarchical topology having a single or much less nodes on top level in a very large network like data center, there exist a chance for network congestion and a small portion of available bandwidth is supported for end hosts.

● Flat: where all the interconnection equipment have the same functions. Topology is easier to implement and has a great ease of management, provided that the network does not increase, then being recommended for small networks. ● Hierarchical: In this model the topology is divided into discrete layers, and each layer is focused on a set of specific functions, allowing the choice correct equipment for each layer. A typical hierarchical topology is composed of layers of core, composed of high-tech equipment, optimized for performance and availability, distribution, where they are concentrated equipment that control the flow of information across the network and access layer, formed by equipment that provides the connections for the network users.

-it is relatively easy to troubleshoot problems on this topology -the network services require no reconfiguration if the network structure changes -there are no device installation difficulties
A star topology has a central hub with other devices each connected to the hub but not to each other - for one device to communicate to another, they have to use the hub. With a bus topology all the devices are connected to the same bus - there is no hub. Each topology has advantages and disadvantages; the speed of a star network is limited by the hub; a telephone exchange is an example of a star network and there is a built-in limit to the number of devices that can be connected and there's no way to increase it other than to replace the hub with a bigger one. However, the devices (telephones in our example) can be dumb - all the intelligence is in the hub; it manages the calls and importantly, for commercial exchanges, calculates the bills. For bus networks, devices have to be smarter but can do much more as they can grab the whole bus.

you can cut logs out of it
Four collision domains are present Two broadcast domains are present.
Some advantages of tree network topology include easy to set up and extend. It is also inexpensive. Its disadvantages, on the other hand, include limit on central cable length and number of nodes.
hierarchical databases are fast and conceptually simple however do not support many-to-many relationships and have a lack of referential integrity. dan woodfield was a creater of Hierarchical Databases

A network structure is more a star topology whereas a Hierarchical structure is like a tress... Allowing you to drill down to get to an answer.
The hierarchical system has its advantages in that all those that live in a system understand what extortionists they need to pay and obey.
