What is the OSI model in a computer network? OSI Model Introduction: OSI stands for Open System Interconnection. It is used for designing network architecture. It was designed by the International Standard Organization (ISO) in 1983. It provides a logical framework for any type of data communication through computer networks. This model provides the reference in a system but not the reality. Therefore, the OSI model is also known as the OSI Reference Model. Purpose of OSI Model: The purpose of the OSI model is to open communication between different systems, without requesting changes to the logic of the underlying hardware and software. The OSI model is not a protocol in IP; It is a model of the network system for understanding and designing network architecture. It deals with the open system. An open system is one, which is open to others for the purpose of information exchange. Layers of the OSI Model: OSI model consists of 7 layers. Each layer is responsible for performing a partic...
