There are a couple of different ways you could do this. If you want to start working as soon as possible and don’t want to study for very long you should pursue a Computer Technology degree program at the associate level. The duration of this program tends to be around 20 months but some colleges will allow you to complete it in as little as 15 months. However, if you want a broader, more diverse range of knowledge and training, I would advise you to pursue a Bachelor degree in Computer Science with a Networking emphasis which will take you 30-36 months to complete. Whichever degree you choose to pursue, make sure it is from an accredited, well rated educational institution.
