What is OSI and what role does it play in computer networks?

OSI (Open Systems Interconnect) serves as a reference model for data communication. It is made up of 7 layers, with each layer defining a particular aspect on how network devices connect and communicate with one another. One layer may deal with the physical media used, while another layer dictates how data is actually transmitted across the network.

ISO/OSI Model in Communication Networks

There are n numbers of users who use computer network and are located over the world. So to ensure national and worldwide data communication systems can be developed and are compatible to each other. ISO has developed this. ISO stands for International organization of Standardization. This is called a model for open system interconnection (OSI) and is normally called as OSI model.

The ISO-OSI model consists of seven layer architecture. It defines seven layers or levels in a complete communication system.
