i'll give some of these a go.
I'm a network administrator (technically THE network administrator for my company)
1.type of training
i've got an associates of applied science - computer networking systems degree
2.what schools do you recomend
i got my degree from ITT Tech, and depending on the quality of your local campus, i recommend ITT as a viable alternative to "regular school". in my experience they're a very good technical school and i feel like i got my money's worth
3.how hard is it to find employment
anywhere from very, to extremely? depends on what your specialty is, what your education level is, what your experience is, what your local job market is, what price range you're looking for, etc.. etc.. etc.. it's an extremely poor job market right now so it's hard to say for sure
4.how much experience is required
to get a job in IT in a government run facility with top secret security clearance, a lot. to load paper in printers at your local car dealership, probably not that much.
not sure what this means
6.entry level salary
depends on your location, your experience level, your education level, and the company you land a job with, but anywhere from $25k a year to $60k a year seems reasonable as an estimate
7.physical nature of job (very little use of my legs)
depends on the job you're going after. in my job i do a lot of walking because i support every electronic device in the building, and our building is close to a half mile long. if you go into programming, then you can expect to sit in your chair all day.
8.what the best thing and worst thing about your job
best: i get to do a job that i really enjoy, i get a lot of freedoms, and i get to play with a lot of fun toys. Worst: dealing with users who SHOULD know what they're doing but don't
9.a typical career path (advance,specialization)
entirely too broad to define
10.finaly what advice would you give me if i go in to this field of work.
be sure now that it's something that you want to do, working in IT isn't for everyone (just because you know a thing or two about computers, doesn't mean you'll enjoy working with them every day). also pick a specialty that will be your go-to skill on a resume, but don't just focus on it. having a lot of tricks up your sleeves will make you much more employable
