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 ...

A tutorial on the Open Systems Interconnection (OSI) networking reference model plus tips on how to memorize the seven layers. The Open Systems Interconnect (OSI) model is a conceptual framework that ...

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 ...

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. So far, we've talked about the tangibles of your ...

Thanks for your comments on my first EtherGeek post on understanding the OSI Model. I especially enjoyed learning new ways to remember the OSI Model; for example: Please Do Not Throw Stale Pizza Away.

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 model ...

Other tips in this series have examined the seven-layer OSI model from the perspective of security. Although security was not the No. 1 goal of the designers of the OSI model, the idea behind these ...

A couple posts ago, we talked about Layer 1 of the OSI Model — the Physical Layer. Today, we’ll start our climb up the Model with a visit to Layer 2, the Data Link Layer. The Data Link Layer is one of ...

Most IT users will be familiar by now with the idea of `the software-defined something or other’. Indeed, there vendors that already talked about software-defined everything, which really should cover ...

For many in the communication industry, the open system interconnect (OSI) network model is a simply a stack. But, designers shouldn't be so quick to diminish the value that the OSI model provides to ...
