Hi guys
Im going for an interview on Thursday and the main thing I should know about is Routers including all other pc things that I am happy with.Within Regards to Routers Im currently doing some research because I never really worked on them.Basically im briefing myself from scrap just to get a feel what Routers is actually about.
I was hoping that theres someone that can guide as to what I am to know in order to get a better understanding of Routers.

All help is greatly appreciated
