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.

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 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).

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 ...

One of the most enduring models in networking is the famous seven-layer OSI model. X.25 roughly, but pretty accurately, is based on the first three layers. And it stopped there. Subsequently ...

A dive into the seven-layer Open Systems Interconnection (OSI) model. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The OSI model is a product ...

Open System Interconnection, a layered model for network transport and applications. For instance, the seventh layer in the OSI model—the Application layer—defines program to program communication, or ...

The OSI model is a layered model that describes how information moves from an application running on one networked computer to an application running on another networked computer.

Layer 2 of the OSI model is where we find the Data Link Layer, which provides the mechanism by which data is transferred from node to node across a network. What makes this layer important is that ...
