What are the three layers of the hierarchical network design model?
Wiki User
∙ 11y ago
A hierarchical network design includes the following three layers:
The backbone (core) layer that provides optimal transport between sites
The distribution layer that provides policy-based connectivity
The local-access layer that provides workgroup/user access to the network

Why is the OSI model useful in network design and assessment?
The OSI model is useful in network design and assessment because it makes network communications more manageable by dividing the processes up into smaller parts. The processes are broken up into 7 layers and each layer serves the one above it.
What are three benefits of employing a hierarchical network design?
Hierarchically designed networks can more easily be expanded to suit future needs.Hierarchical design models enhance existing bandwidth through the use of link aggregation.The hierarchical model allows for specialized functionality at each layer, simplifying device management
What are the difference between hierarchical database and network database?
Hierarchical databases organize data in a tree-like structure with parent-child relationships and a strict one-to-many hierarchy, while network databases use a more flexible model with many-to-many relationships through pointers or links between records. Hierarchical databases are faster for accessing data along predefined paths, while network databases allow for more complex data relationships but can be more complex to manage.
Why do you learn database model?
It helps you to design a database. It is a theoretical idea of what it will be like. There are different models than can be used, such as relational or network or hierarchical. Some are better suited to some kinds of databases. Using the model helps people to design and build better databases.
