Well, i am thinking of doing any refresher course, i am an IT engineer (no practical experience), can you tell me which course (cisco or linux) will help me to develop my future. Many Thanks.

I’ve been thinking really hard to go to school this fall for Computer Network System Administrator. I was planning on completing an Associates degree for it. I just want to make sure by the time I complete the 2yr degree there will be a job available for Computer Network System Administrator. I am planning on taking the class at a community college. Thanks ahead of time!
