The OSI reference model was a major advance in the standardisation of network concepts. The Open Systems Interconnection (OSI) model describes seven layers that computer systems use to communicate over a network. It was the first standard model for network communications, adopted by all major computer and telecommunication companies in the early 1980s The modern Internet is not based on OSI, but on the simpler TCP/IP model.

While many protocols fit neatly into one of the seven layers, others do not. But OSI reference model (Open Systems Interconnection): OSI (Open Systems Interconnection) is reference model for how applications can communicate over a network . A reference model is a conceptual framework for understanding relationships. The purpose of the OSI reference model is to guide vendors and developers so the digital communication Datas are transported as “bits”.

It is primarily used today as a teaching tool. It conceptually divides computer network architecture into 7 layers in a logical progression. 2018-07-13 · The Data Link Layer of OSI Model Computer Network Computer Engineering MCA The data link layer (Layer 2) converts the raw transmission facility provided by the physical layer to a reliable and error-free link.

The OSI model has two major components: the basic reference model and protocols. The basic reference model is just another way to describe the 7-layer model.

T OSI stands for Open Systems Interconnection. It has been developed by ISO – ‘ International Organization of Standardization ‘, in the year 1984. It is a 7 layer architecture with each layer having specific functionality to perform. All these 7 layers work collaboratively to transmit the data from one person to another across the globe.

The network layer passes the packet to the data link layer for the next hope. The OSI model presents a standard data flow architecture, with protocols specified in such a way that the receiving layer at the destination computer receives exactly the same object as sent by the matching layer at the source computer. Figure A.2 shows the OSI model data flow. The sending process passes data to the application layer.
