The internet protocol suite is the protocol stack used on the internet. It is usually called TCP/IP after two of its most important protocols but there are other protocols as well. The TCP/IP is based on a five-layer model for networking. These layers are the physical, data link, network, transport, and application layers. The physical layer contains all the functions needed to carry the bit stream over a physical medium to another system. This layer has four parts: mechanical, electrical/optical

Network protocols In this essay I will explain the functionalities of different types of protocols, what are they? why are they used? And how networks benefit from them, also on how layers work in the OSI model. I will also explain on how layers work with protocols and how they function together. OSI Model/layers OSI model has been created to understand on how one computer can get to one network,connected which is connected by using cables or wirelessly to another computer. OSI model has
