Jan 20, 2025 · The OSI (Open Systems Interconnection) Model is a set of rules that explains how different computer systems communicate over a network. OSI Model was developed by the International Organization for Standardization (ISO).

Learn about the OSI Reference Model, its layers, and functions. Understand how this model facilitates communication in network systems.

The Cisco Learning Network has developed an OSI model chart to help aid in your learning. This chart organizes and describes the seven layers, providing examples in the form of protocols and devices, as well as in relation to the DOD TCP/IP Model.

Dec 21, 2020 · This article explains the Open Systems Interconnection (OSI) model and the 7 layers of networking, in plain English. The OSI model is a conceptual framework that is used to describe how a network functions. In plain English, the OSI model helped standardize the way computer systems send information to each other.

Mar 27, 2025 · OSI stands for Open System Interconnection is a reference model that describes how information from a software application in one computer moves through a physical medium to the software application in another computer. OSI consists of seven layers, and each layer performs a particular network function. OSI model was developed by the ...

Sep 10, 2024 · In this tutorial we will learn about OSI Model, OSI Model Features, Principles of OSI Reference Model, All the different layers of OSI Model and their functions in details.

Mar 26, 2025 · This tutorial explains the OSI reference model. Learn the seven layers of the OSI model and the functions of each layer in detail through examples. The OSI (Open System Interconnection) reference model is a comprehensive set of standards and rules for hardware manufacturers and software developers.

The OSI model consists of seven layers that cover all phases of a computer network. The OSI (Open Systems Interconnection) reference model was developed by ISO (International Standards Organization) which describes functions and services at its seven layers.

The seven layers identified by ISO in the OSI reference model from bottom to top are: 1. Physical Layer 2. Data Link Layer 3. Network Layer 4. Transport Layer 5. Session Layer 6. Presentation Layer 7. Application Layer.

OSI (Open Systems Interconnection) is a reference model for how applications communicate over a network. This model focuses on providing a visual design of how each communications layer is built on top of the other, starting with the physical cabling, all the way to the application that's trying to communicate with other devices on a network.
