  • Great video. I know nothing about IT but got convinced to get my network + certification. I figured it was no big deal. I'd figure it out until I got into my comptia coursework. I quickly learned that I need to learn so much and I also need to learn the fundamentals before network plus because this stuff has so many abriviations and terms I don't know/understood and even when I learn the definition I don't hate any knowledge of how or why to apply it. But this video does help me understand at least this one model.
