This term is generally also used to refer to a more generalised collection of protocols developed by the internet community and U.S. Department of Defence. 2.7 Advantages of Layering in TCP/IP architecture: Layering is the process which is used and helped to reduce the overall problem, which is huge in size, to number of sub problems, which are manageable is size. 2.8 Router: A router is a device that is used to connect dissimilar device. It is present and operates at the Network layer of the OSI model. 2.9 Version of IP, that is prevalent today: IPv4, is the version of IP that is prevalent today.
