From the Paper:

"The open systems interconnection (OSI) has been developed by the International Standard Organization (ISO) to maintain a standard for the exchanging of information within a network of communications. It basically comprises seven layers of rules that would serve as a standard for the communications networks all over the world. The seven layers attempt to define abstract ideas on these issues. The Reference Model as it is called underlines the various means through which communication takes place. It breaks up all the functions into easily identifiable layers. Layer 1 therefore comprises the actual physical layer of the network that would include wires, plugs and signals that receive and send out communications to the network. Layer 2 is the data layer that transfers the physical bulk of the data from one computer to the other one."
