Sunny Classroom

Hello, my name is Sunny Sun, Associate Professor of the Cybersecurity Program at the University of Saint Mary (USM), Kansas.

I have been teaching at USM many different computer courses of both Computer Information Systems and Cybersecurity: Web design (HTML, CSS, & PHP), Networking, Ethical hacking, Cryptography, Digital forensics, Database, Data structure & algorithms, and computer programming ( Java, C#, and Python). I enjoy teaching.

I hope these videos are helpful in your study or as you prepare for the national certification tests (CompTIA Network+/Security+, CCENT, or CCAP).

Thank you very much for your support by becoming a Sunny Classroom member. Your support is much appreciated. www.patreon.com/sunnyclassroom

    Hopefully someone can help me out here even though it's been a few years since this video was up, but how did he get to the number 63 for the Broadcast ID? Many thanks whoever is willing to educate me.

    Awesome way to subnet. Really simplifies subnetting. ❤ However, I have the same question as @orcnewmymail. What would this table look like with less Network bits? And sacrificing an entire subnet is totally new to me.

    Sorry if this is a blonde question but in the real world - who choses what your original ID is? A lot of the case studies I see in textbooks start with "you've been given this network ID with this mask, generate n number of subnets." What I don't understand about all of this is, how does this original network ID get generated for a business or organisation, and how does it get passed down for you to work on? Second question - it looks like there is not a fixed limit for the number of hosts and subnets. The table in the last video stopped at 256, this one stops at 65536. Are there realworld practical limitations on the number of devices a business can include in a subnet? Thank you so much for your videos - you are my first ever KZread subscribe because they are wonderful.
