    Exploring Communication Protocols: Circuit Switching, Packet Switching, and the Role of OSI in Network Design Explain the importance of communication protocols in networking, highlighting the differences between circuit switching and packet switching. Discuss the advantages and disadvantages of both, and analyze how Open System Interconnection (OSI) plays a crucial role in network communication. In your response, be sure to include the significance of Transmission Control Protocol/Internet Protocol (TCP/IP) and Asynchronous Transfer Mode (ATM) in modern networks. Provide a comprehensive explanation, including real - world applications where these protocols are used. Your response should be 700 - 800 words.

    Protocol Paper Communication for networks is vital to any organization. In order to do this many considerations on how a company can accomplish this is by several methods of communications. It is important to know the communication model, how data moves through a system, advantages and disadvantages of circuit and packet switches. Considerations for performance, speed and throughput potential. The reliability and predictability of end - to - end transmission. The importance of the major protocols for circuit switching and packet switching. Considering these choices are a vital part of any network protocol. Open System Interconnection OSI or Open System Interconnection is how applications can communicate over a network by using a reference model. The reference model’s purpose is to make it to where venders and developers’ products can interoperate. “Developing OSI in 1983, was created and intended to be detailed specifications of actual interfaces (Rouse, 2014).” The OSI is a seven layer interface. Now this interface work backwards starting with layer seven the application layer. This layer is not the application itself more it’s the communication layer. It answers the question is there someone to talk to on the other end and can I talk to the other end right now. Layer six, the layer which represents the operation system converting data coming onto and out of the network from one format to another. Layer five encompasses the session layer, coordinates and terminates the conversations. Including authentication and reconnection after interruptions. Layer four is the transport layer managing the packetization of the data, delivering packets, and checking for errors once data arrives. Layer three, network layer handling addressing and routing. Layer two handles data - link layer across the physical network and sending packets to the network frames. Containing two sub layers the logical link and the media access control layers, using Ethernet as the main data link. Layer one contains the physical layer conveying the bit stream by electrical, optical, or radio level throughout the network. Providing sending and receiving the data hardware on a carrier network. The diagram below is the way the OSI works (Rouse, 2014): (rouse, 2014)
