Job in computer programming or to do with computers

is this what you're doing "computer and network systems security"
I just looked into that. They have it at the college im going to.

I guess. My major calls it as "CIS: Computer Networking" though, if un-abbreviated, it's:

Computer Information Systems: Computer Networking

I'll describe it as best as I can. I had to go through a PAINFUL 4 semesters of learning about:

-IP addressing (A, B, C types)
-Subnetting an IP address
-Learning the functions of a: Router, Switch, Server, etc
-Learn how to build a Wide-Area Network (WAN)
-Learn to use a network simulator ; Packet Tracer
-Learn how traffic goes from a router to a switch, etc
-Learn how data is processed, and 'priorities'
-Learned how to program routers:

Such as learning how to set usernames, passwords, security for a router, pretty much. Learning how to make banners for routers, learning how to make routers talk to each other, by connecting them to a switch. Learning about debug mode when messing around with routers.

When I say routers, I don't mean those small miniature ones you buy such as Netgear. I mean real corporate routers.. But yeah, if you're interested in stuff like this, give it a shot. I will warn you now, it isn't easy sh't. I don't know if it's just my professor's expectations, or the course's curriculum or what, but those CISCO courses were a killer!

Also, this is only the tip of the iceberg. There's a lot more I learned that I didn't include in this. Some other classes I've taken:

-Client Operating Systems
-Server Operating Systems
-PC Hardware
-Network Security
-Disaster Recovery Planning
-HelpDesk Concepts
-Keyboarding (LOL 1 credit class that's online)
-And of course, my 4 CISCO courses: Introduction to Networking, Routing and Traffic, Switching and LANs, WANs and the enterprise.
