The Physical Layer includes cable specs, pin-out patterns, voltages, hubs, repeaters, network cards, protocol standards (RJ45, V series modem standards) and even host bus adapters (HBA).

If you have anything to do with networked AV and you're not well-versed in the OSI model, we've got you covered. You will learn the fundamental ideas around getting data from host A to host B over a ...

In this two-part series, we'll provide a different view of the OSI model, showing how the layers are interconnected and what protocol services are available at each level. In Part 1, we'll provide a ...

The basic idea behind the OSI reference model is this— Each layer is in charge of some kind of processing and each layer only talks to the layers immediately below and above it.

Understanding Protocols and the OSI Network Model Getting a handle on the invisible part of your network—the protocols that are in use—can be of enormous value in helping you detect problems.

The Data Link Layer is one of my favorite layers of the OSI Model. Like a father who loves ALL of his children equally, but in different ways, I also love the other layers, but Layer 2 will always ...

The OSI model defines protocols for how a network technically handles communications at the various functional layers. Starting with electrons and photons at the physical layer (Layer 1), the ...

Explains the three layers critical to network design: Access, Distribution, and Core Anyone involved in networking and/or telecommunications should be somewhat familiar with the use of layers ...

The Open System Interconnect (OSI) network model, referred to by many as simply a stack, is in fact a well-designed, layered architecture for efficient intersystem and intrasystem communications. In ...
