The PHY is a key component of the Open Systems Interconnection (OSI) model, which contains seven abstraction layers for ...

A tutorial on the Open Systems Interconnection (OSI) networking reference model plus tips on how to memorize the seven layers.

The OSI model differentiates computing functions into a worldwide set of rules and requirements to hold interoperability between diverse products and software. To know more about the OSI Model and its ...

First, and foremost, the OSI stack is just a theoretical reference model. There is no actual OSI software. It has been around since about 1980, and it is based upon recommendations from the ITU-T and ...

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 ...

There are two key points to make about the OSI model. First, the OSI model is just that, a model. Its use is not mandated for networking, yet most protocols and systems adhere to it quite closely.

The third layer of the OSI Model, the network layer, is where most network engineers focus their time and expertise. As Darragh commented in my post on the data link layer, Layer 2 is cool but ...

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).
