Basic networking info

[Hitmanric]

A question from an absolute "newb" in networking. An apprentice/on site learning position at work opened up in the networking dept. Before I jump into something like this is there anywhere on this site or elsewhere on the net I could get a peek into what a job like this would entail? I was told the position is more like a network/systems administrator. I realize most of the questions on this site seem to be home networking in nature. I'm trying to get an idea before I start looking into courses and the such. Any help or opinions would be appreciated.
