What do you mean by the TCP/IP Model?

TCP/IP Model helps you to determine how a specific computer should be connected to the internet and how data should be transmitted between them. It helps you to create a virtual network when multiple computer networks are connected together. The purpose of TCP/IP model is to allow communication over large distances.

TCP/IP stands for Transmission Control Protocol/ Internet Protocol. It is specifically designed as a model to offer highly reliable and end-to-end byte stream over an unreliable internetwork.

   Explain the different Layers of TCP/IP Model.
   

Like OSI reference model, TCP/IP protocol suite also has a model. The TCP/IP model is not same as OSI model. OSI is a seven-layered model, but the original TCP/IP is a four layered model.

The OSI reference model has been very influential in the growth and development of TCP/IP standard, and that is why much OSI terminology is applied to TCP/IP. The TCP/IP model which we use today is slightly different from the original TCP/IP model. The original TCP/IP model had only four layers, but the updated TCP/IP model has five layers.

The four layers of original TCP/IP model are Application Layer, Transport Layer, Internet Layer and Network Access Layer.

etailed explanation about different layers of original four layered TCP/IP model is given below.
