OSI is a seven layered architecture used to establish communication between 2 systems which have nothing in common like they are in different networks, having different hardware and software, having different internal architectures. Those seven layers are: physical , datalink, network, transport, session, presentation and application. Each lower layer provides its functionality to the layer above it.
