This tutorial explains OSI Reference model step by step. The OSI Open System Interconnection Reference Model is the comprehensive set of standards and rules for hardware manufacturers and software developers. By following these standards, they can build the networking components and software applications which work in dissimilar environments. The OSI model not only provides a framework for creating and implementing networking standards, devices, and internetworking schemes but also explains the networking from a modular perspective, making it easier to understand and troubleshoot. This tutorial is the second part of the article "Networking reference models explained in detail with examples".

Though eventually computer science and technology continued to be further innovated and become more readily available to companies and the public, it became necessary that a widespread standard would be needed in place to ensure compatibility between all machines. This was especially true about networks, and networking technology. A network is designed to share data and information between machines, a standard that dictates how this information is formatted, transmitted, and received would make it easy for data to be shared openly, even when sending or receiving from networks that are not similar. The OSI model is made up of these seven layers; the physical layer, data link layer, network layer, transport layer, session layer, presentation layer, and application layer. Here are the 7 layers in further detail: Physical Layer The physical layer defines all the mechanical, procedural, functional and electrical specifications for activating, deactivating and maintaining the link between each system.
This lesson features video of our top instructor, Eric Coll, explaining the FedEx analogy to you via the camera along with animated graphical illustrations. Lesson 3 Protocols and Standards, where we will understand what a protocol is, monolithic vs. Then we'll go over that again, more slowly, one layer at a time.
IP address is one of the best known example of network address. Machine address is unique identifier for a host which is also known as Host number. Machine address….
