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).

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 ...

Now that we have completed the seventh layer, some may think we are through. The OSI model is a framework for data communications, but does security stop there? No, there is the mythical eighth layer.

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 ...

In response to this problem, engineers developed the open systems interconnect (OSI) layer model for networking. This layered model allows the application (an accounting program, editing application, ...

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.

Many of the functions of the Distribution layer require the use of routers, so there must be some very careful planning at this layer to ensure that these devices can handle Layer 3 OSI model ...

Whether it’s wired or wireless, most data communications today happens by way of packets of information travelling over one or more networks. But before these networks can work ...

1. Introduction This paper will cover general aspect of verifying layered protocols like OSI Model, PCI Express, etc. This paper is not going to cover the complete verification of OSI Model but ...
