No problem. A router is a box that basically sits between your computer and the DSL modem. Normally it's used to allow you to hook up more than one computer to a DSL or cable internet connection, but ones that have a built-in firewall also provide protection from hackers and such. If you're online through Verizon DSL, you may already have a router (combined with the DSL modem). You can call your DSL provider to find that out. If not, you can pick up a router from any computer place (CompUSA, Best Buy, etc).
Linksys and Netgear generally make pretty decent routers. Linksys products are listed
here, and Netgear's router offerings are listed
here. You can browse on their sites to see which ones you might be interested in, and then go check out what your local Best Buy or CompUSA has to offer. Do your own research though, as the people they have working in those places often don't know a hard drive from a hamburger, but will act like they do to make the sale. :-)
