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 ...

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 ...

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 ...

Layers 7 through 4 are geared more to the application than the lower layers, which are designed to move packets from one place to another no matter what they contain. This top layer defines the ...

As cybersecurity threats grow more sophisticated, traditional network architectures struggle to keep pace, especially in sectors reliant on legacy hardware. IMPRES Technology Solutions has introduced ...

Getting started on designing a network is a task of formidable proportions, but all the more so if you are looking to build a secure IT network. Often, IT system administrators are not fully familiar ...

We recently advised that people in the business of planning, building and supporting computer networks should not lose sight of the mythical OSI Layer 8. We define Layer 8 as the human-to-human ...

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.

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 ...
