I have a data processing degree and been a computer programmer, help desk administrator, computer trainer, computer instructor, and am now a computer educational program administrator. My area is saturated with programmers since the dot.com explosion, and because of out-sourcing and layoffs.
In spite of that, the computer and medical fields are still the hottest fields to get into...but you have to pick the right part of the field, be flexible, and keep your skills up. Why are they so hot? The baby boomers are retiring, and the outsourcing has scared people off. We have a 50?eduction in computer students at our college alone. So what's popular? According to the US Dept of Labor, these are the some of the fastest growing occupations for 2004-2014 and are all in the computer field (they usually require a bachelors degree and usually make over $43,000):
1) Computer scientists and network systems and data communications analysts
2) Computer software engineers, applications
3) Computer software engineers, systems software
4) Network and computer systems administrators
5) Computer scientists and database administrators
6) Computer systems analysts
So you've picked one of the best, networking, since it's hard to outsource setting up and trouble shooting your local network for your firm. Here's the link to the descriptions of the jobs:
http://www.bls.gov/oco/oco1002.htm Programming jobs and Help desk/support jobs are still being outsourced so demand is up and down. Depending on the area of the country you live in, programming jobs can be found if you have lots of experience or they can be scarce, like they are where I live, since thousands of programmers have been laid off in my area.
Good luck!
