The OSI, or Open System Interconnection, model defines a networking framework for implementing protocols in seven layers. Control is passed from one layer to the next, starting at the application layer in one station, proceeding to the bottom layer, over the channel to the next station and back up the hierarchy.
The Open Systems Interconnection model which is developed by ISO in 1983 is used as a framework to explain networking basics and troubleshoot networking issues is called as Network Security Model. It is a seven layer model. Following are the 7 layers of Network Security ModelPhysicalVLANACLSoftwareUserAdministrativeIT Department
The OSI model is a standard developed by ISO for designing of computer networks.OSI stands for Open Systems Interconnection and was created by ISO, the International Standards Organization.The OSI "reference model" divides particular networked processes into seven different layers:Application (Layer 7)Presentation (Layer 6)Session (Layer 5)Transport (Layer 4)Network (Layer 3)Data-Link (Layer 2) andPhysical (Layer 1)There are at least 2 ways (mnemonics) to help you remember the layers:1. Please Do Not Throw Sausage Pizza Away.2. All People Seem To Need Data Processing.OSI stands for Open System Interconnection model

The main idea in OSI is that the process of communication between two end points in a telecommunication network can be divided into layers, with each layer adding its own set of special, related functions The open systems interconnection (OSI) model was created to standardize the rules of networking in order for all systems to be able to communicate OSI Reference Model, a set of seven layers that define the different stages that data must go through to travel from one device to another over a network
