The switch modes you program a switch to use make a big difference!
All network switches read the incoming frames they receive to make a filtering decision on the destination to SEND that information over to. But there are 3 MODES on that switch that can be used to make that decision? Want to know how drastic the effects can be on the entire network for each of these modes on that network switch?
The Ethernet Frame Preamble
What’s in a network frame preamble and how does it work?
I’m gonna give you the simple answer to those questions right now!
So I talked about the portions of a network frame in another video, but I left the Pre-amble out of that video (for several reasons, but) primarily because when you study textbooks on computer networking, they will always tell you the Pre-amble is NOT part of the frame, but when you actually sit down to take a certification test, the testing material and questions will oftentimes make the assumption the pre-amble IS part of the frame.

What Is Ethernet?
So what is ethernet? If you’re learning about computer networking and you want to understand networks and how they communicate and work, ethernet is one of those basics.
What really is being referred to by the term Ethernet? I’m gonna show you in just a few seconds exactly what it is and why it’s needed for computer networking.
But first, you have to understand that a network design (for it to work and function correctly) it has to have…
