The Open Systems Interconnection model (OSI model)

This file contains all about The Open Systems Interconnection model (OSI model). It's principles, features, functions of different layers, etc.

OSI Model & TCP/IP Model (Data Communication and Networking)

OSI or Open System Interconnection model was developed by International Standards Organization (ISO). It gives a layered networking framework that conceptualizes how communications should be done between heterogeneous systems. It has seven interconnected layers. The seven layers of the OSI Model are a **physical layer, **data link layer, **network layer, **transport layer, **session layer, **presentation layer, and **application layer.

Network layers and TCP IP

Many networks have a 5 layer architecture that divides up communication responsibilities. The physical layer is responsible for encoding bits onto a transmission medium. ... The network layer is responsible for delivery of information between different machines on the internet. TCP/IP, or the Transmission Control Protocol/Internet Protocol, is a suite of communication protocols used to interconnect network devices on the internet.
