Exploring Communication Protocols: Circuit Switching, PacketSwitching, and the Role of OSI in Network DesignExplain the importance of communication protocols in networking, highlighting the differencesbetween circuit switching and packetswitching. Discuss the advantages and disadvantages ofboth, and analyze how Open System Interconnection (OSI) plays a crucial role in networkcommunication. In your response, be sure to include the significance of Transmission ControlProtocol/Internet Protocol (TCP/IP) and Asynchronous Transfer Mode (ATM) in modernnetworks. Provide a comprehensive explanation, including real-world applications where theseprotocols are used. Your response should be 700-800 words.

Protocol PaperCommunication for networks is vital to any organization. In order to do this manyconsiderations on how a company can accomplish this is by several methods ofcommunications. It is important to know the communication model, how datamoves through a system, advantages and disadvantages of circuit and packetswitches. Considerations for performance, speed and throughput potential. Thereliability and predictability of end-to-end transmission. The importance of themajor protocols for circuit switching and packet switching. Considering thesechoices are a vital part of any network protocol.Open System InterconnectionOSI or Open System Interconnection is how applications can communicate over anetwork by using a reference model. The reference model’s purpose is to make itto where venders and developers’ products can interoperate. “Developing OSI in1983, 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 startingwith layer seven the application layer. This layer is not the application itself moreit’s the communication layer. It answers the question is there someone to talk to onthe other end and can I talk to the other end right now. Layer six, the layer whichrepresents the operation system converting data coming onto and out of thenetwork from one format to another. Layer five encompasses the session layer,coordinatesandterminatestheconversations.Includingauthenticationandreconnection after interruptions. Layer four is the transport layer managing thepacketization of the data, delivering packets, and checking for errors once dataarrives. Layer three, network layer handling addressing and routing. Layer twohandles data-link layer across the physical network and sending packets to thenetwork frames. Containing two sub layers the logical link and the media accesscontrol layers, using Ethernet as the main data link. Layer one contains thephysical layer conveying the bit stream by electrical, optical, or radio levelthroughout the network. Providing sending and receiving the data hardware on acarrier network. The diagram below is the way the OSI works (Rouse, 2014):(rouse, 2014)
