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 ...

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 ...

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 it ...

Explains the three layers critical to network design: Access, Distribution, and Core Anyone involved in networking and/or telecommunications should be somewhat familiar with the use of layers. Many ...
