OSI stands for The Open Systems Interconnection model and is a conceptual standard that is used for creating standards among the communication functions of telecommunication and computing systems without basing itself on the architecture and other internal structures.
The primary task of OSI model is to create different standards than the ones existing in the inner and outer architecture, and it does so with the help of seven different layers. The first layer is a physical layer that takes all the bits and then streams them over the network; the data link layer helps with the transmission of current information frames by connecting two nodes. Network layer works on the structuring and managing of multi-nodes connection. Transport layer moves segments between a point and the system.
Session layer works on the management of sessions taking place in the constant exchange. Presentation layer cares for the translation of data between the service and the application for factors such as encoding and decoding. Lastly, the application layer works on high-level languages and API’s including features as remote sharing. Mostly the data moves from the topmost layer and goes to the lowest layer, and this process continues for each packet.
