Hi Keith. I watched your videos back around 2012-13 when I just graduated from a computer degree but ironically still know nuts about networking. The videos back then are a paid subscription service purchased by my then employer and it was offered to all employees. This series of video literally build my career in the IT. I love the way you make complex things simple and appreciate your teaching style. It's 2020 and now I'm a VP in a fortune top 20 bank, loving and doing technology work and getting paid well for it. I must say these instructional videos had great impact to my career and I wouldn't be in the same place without shoulders of giants such as yours to stand on. I am sharing this to people who needs this knowledge now that it's available on Youtube. Thank you sir.

I am fan of your teaching and watching your videos more than 10 years . Best thing about Keith is his consistant smile and ability to create interest in whatever he is teaching, simplistic drawings and close to real life scenarios. Instead of learning the subject it his teaching skills which captivates learner inside me. I wish Keith I could find more videos from you on upcoming automation, virtualisation, cloud technologies such as AWS, Azure, Google etc which skills we we need now for next decade or for being our mentor..

I have seen theese 14 short videos on networking, and i can say this is the best teacher i have seen on this subject. I am seriously thinking to take his course to fill the gaps in my knowledge. I have seen hundreds of hours from different teachers, and if you are like me, ADHD and reading a lot is not enough to let you understand the consept, or reading take too long. This is the way to go, i love this teachers method and whats best with him is he loves doing this, and that is why he is the best teacher out there.

I've been on years' long vacation since last studying networking. Brushing up. Is a regular RJ 45 used to connect switches together or is a crossover cable required?
