- Explore devices that operate at the Transport layer (Layer 4) of the OSI model, outlining their functions and importance.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.Complete the table below by analyzing any of the given IoT (Internet of Things) applications: IoT Architecture layer Deviced used Device layer Gateway layer Platform Layer
