Why the OSI model useful in networking design and assesment?
It allows categorisation of network components in both functionality and complexity.
Why is a Network Architecture model useful?
It allows vendors to design products following the model, so different devices from different manufacturers will work together.
Which layer of the hierarchical design model provides a means of connecting devices to the network and controlling which devices are allowed to communicate on the network?
distribution
Which statement accurately describes what network devices do in the distribution layer of the three layer design model?
prevents collisions on a local network.
What are the 3 layers of the cisco hierarchical model?
From a network design standpoint: Core Distribution Access
What is the risk assessment model for?
The risk assessment model provides a process structure to guide you in assessing risk.

What are the three benefits of hierarchical network model?
Reduced content for bandwidth Increased fault tolerance of the network Simplification of management and troubleshooting
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.
What network did Defense advance research project agency design which became a model for the internet today?
TheAdvanced Research Projects Agency Network(ARPANET) was the world's first operationalpacket switchingnetwork, the first network to implement TCP/IP, and the progenitor of what was to become the globalInternet.So the answer is ARPANET
