TCP/IP & OSI Models for Beginners

I have been addicted to networking ever since the first time I heard about the CCNA certification. I remember hearing everyone say how big of a deal it was, which made me want it more than anything. I was climbing towers for a living at the time in sub zero temperatures. All I could think about was how getting my CCNA certification could be a way to a better opportunity. I told myself that one day I would be CCNA certified. After a lot of studying and time in the lab…..I passed! Now I am a Senior Systems Engineer and all I do is Cisco networking. Every time I pass a cell tower I think about how much the CCNA has changed my life and I am grateful. 
I decided to become a CCNA instructor during my path to the CCNA certification. While I tried different courses with terrible instructors…I thought about how I wished I could teach students a better way. Now with Udemy, I can.
