Re: general computer know-how
Better yet, take a class on building, upgrading, and troubleshooting computers. Every college has a different curriculum title, but all teach the same. You don't have to major in it, just take a couple of classes to get some insight on computers. Having an interactive class will make learning easy and fun.
