When implementing a network, one should pay closer attention to how different devices are communicating with each other. The utilization of either the TCP/IP or the OSI model depends on the ultimate specifications of the network and connectivity opportunities established by network administrators. It is important to mention that the two models are affected by a reasonable number of similarities, with the most important of them being the reference model nature of both the TCP/IP and the OSI (Rayes & Salam, 2017). In other words, data communications are established with the help of specifications related to either model. Another crucial factor is the layered architecture characteristic of both models, where network functionalities differ depending on the given layer. There are five layers for the TCP/IP model and seven for the OSI, respectively. This particular feature of both models is rather important since it allows for a more in-depth analysis of network traffic.
In addition to layers, the OSI and the TCP/IP models are functioning similarly in terms of security protocols, with the only variance being the process of implementation, as the number of layers is different for these models. The functionalities of both types of network protocol models are also typically similar, as the Application layer in TCP/IP is synonymous with the three OSI layers (Application, Presentation, Session) and the Internet layer from the TCP/IP being called the Network layer for the OSI model (Howser, 2020). Other than that, data communications within the two models are practically the same, as the two most significant advantages possessed by the OSI model are increased interoperability and standardized networking interfaces. According to Rayes and Salam (2017), the OSI model could be utilized to adapt to different types of protocols as well.
