iscuss the OSI model and its relevance to WAN design and troubleshooting. How does the model help in understanding the different layers of network communication?

Discuss the role of hubs, switches, and routers in the OSI model. How do they differ in terms of functionality and use cases?

Discuss the significance of gateways in the OSI model and how they enable communication between different network protocols.

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.
