What is 80-20 rule of network design?

Explain briefly the merits and drawbacks of using the three most common network architectures.

Provide an outline of the fundamental distinctions between circuit-switching and packet-switching networks.

The Open Systems Interconnection (OSI) Reference Model defines seven layers that describe standards from the physical wire all the way up to the application interfaces on computers. Each layer has a specific function, common among all devices, and a specific way of communicating with the layer above and the layer below in the stack. Answer the following questions: Why is it important to wireless networking to understand the layers of the OSI Reference Model? Fully address the questions in this discussion; provide valid rationale for your choices, where applicable; and respond to at least two other students’ views.    use at least two scholarly articles.

Discuss three network types' pros and cons.

The five most common network architectures should be outlined. To what extent do you trust each?

Do you advocate a particular network design for this situation?
