Detailed explanation-1: -The OSI model has seven layers, as shown in Table 5.1. The layers may be listed in top-to-bottom or bottom-to-top order. Using the latter, they are Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Detailed explanation-2: -7 Layers of OSI Model. The OSI model is broken up into seven layers. Each layer fulfills an important role within the networking stack and communicates with other layers by exchanging protocol data units (PDUs).
Detailed explanation-3: -Layer 7 or the application layer of the OSI reference model deals directly with applications. Within this narrow scope, layer 7 is responsible for displaying data and images to the user in a format humans can recognize. This in turn enables users to interface with the presentation layer below the application level.
Detailed explanation-4: -The OSI Model breaks down network communication into seven layers. These layers are useful for identifying network issues.
Detailed explanation-5: -The main concept of OSI is that the process of communication between two endpoints in a network can be divided into seven distinct groups of related functions, or layers. Each communicating user or program is on a device that can provide those seven layers of function.
