About
If you’ve been in the Network Engineering career field for any small amount of time, then you’ve probably been frustrated at how difficult it was to find articles and videos that were reliable, thorough, and understandable.
You found articles that were very entry level, that perhaps gave simple definitions but did not communicate enough to explain how technologies actually worked. You found articles that were overly detailed, that went into so much minutia that the original point would be lost.
The intent of the blog and video channel is to bridge that gap — providing the happy, practical medium between overly simplistic and overly detailed.
PracNet teaches in a manner that is accessible, easy to learn, and easy to pass on. By presenting complex technology simply, PracNet provides practical, immediately applicable, knowledge of the Network Engineering industry.
