whilst at uni the whole networking thing was quite vague tbh mate as they only teach the basics but while I was working as a techy for a while we did a full install in a school for example, we had to do all the wiring, 16 desktops, 18 laptops, wireless access points, sort the switches out, the server which was a windows 2003 based server but I didnt do much work with that. its been all sorts of stuff really but I could say that a lot of the stuff I've learnt has been self taught as well but also learnt quite a few things whilst working as a techy as I used to go to all sorts of companies to sort their problems out.
as for the position itself mate, either or really, fully time would do me fine or even for a short period of time, either way both would be learning experiences.
