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 ...

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 ...

We have now met the archenemy of networks, Mr. Murphy, as he cackles “What can go wrong, will,” in the introduction to failure modes and the discussion of failure modes at the physical and data link ...

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 met Mr. Murphy, of “What can go wrong, will” infamy, in the introduction to failure modes and the discussion of failure modes at the foundation levels. Now we will learn his tricks on shared media ...

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 ...

This course introduces students to the fundamentals of computer networking, the OSI stack, and the practical and conceptual skills needed to build simple local area networks, perform basic device ...

This article examines netstat and some of it many outputs, in relation to the open systems interconnect (OSI) model. A quick examination of netstat's man pages provides a description of the program: ...
