About the Site
This site features links and articles intended to introduce, illustrate and explain the knowledge and concepts taught in my classes on computer networking & security. If there’s a link I use in class you should find it here. If I find an article online that builds upon or illustrates something discussed in class, I’ll post it here.
I’m Jeff Zahorowski, & I’ve been a technical trainer since 2000. I specialize in networking and information security. In my classes I try to blend my years of experience in training, my previous career as a systems administrator, and my background in radio broadcasting into an effective learning experience. It’s been my pleasure to train clients including Intel (in California, Ireland, Costa Rica & Malaysia), Apple Computer, Oracle, Aerojet, Northrup-Grumman, the U.S. Air Force, and the U.S. Navy Fighter Weapons School (“Top Gun”). In a summer 2012 competition I was the top scorer worldwide on a series of Microsoft Office 2010 certification tests. My certifications include (among others):
- Microsoft Certified Trainer
- Microsoft Certified IT Professional: Server Administrator
- Microsoft Office Specialist Master
- CompTIA A+, Network+, & Security+ Certified Professional
