Eric Leahy’s guide to networking

Hi and welcome to my guide to helping you find the answers to those networking and IT questions you just cannot think off.

On this site I will be going through the different stages (Layers) of networking. Starting from the physical, right on through to what pops up in front of you on your computer screen (Application).

You will also find some very helpful tips on how to study for the big exam. Ways to best use your time and how to think and work through different scenarios, not only for your exams, but also in the real world.

I hope you find what you are looking for, but most of all I hope you find my teaching helpful.

Enjoy the experience of learning!

Many thanks,

Eric Leahy
