Detailed explanation-1: -A hierarchical network design involves dividing the network into discrete layers. Each layer, or tier, in the hierarchy provides specific functions that define its role within the overall network.

Detailed explanation-2: -A hierarchical network is defined as a treelike converging system with multiple inflow points (sources) and one outlet (sink).

Detailed explanation-3: -The Hierarchical internetworking model is a three-layer model for network design first proposed by Cisco. It divides enterprise networks into three layers: core, distribution, and access layer.

Detailed explanation-4: -A hierarchical network is the type of network topology in which a central “root” node (the top level of the hierarchy) is connected to one or more other nodes that are one level lower in the hierarchy (i.e., the second level) with a point-to-point link between each of the second level nodes and the top level central “.
