Been too long since my CISCO classes and I can’t remember the difference between a Router and a Switch. At the moment I have DSL connected to one computer and I want to connect it to another computer. I would also like to use the internet at the same time. So which one would I need and which brand is better? I'm assuming I will want a router for this, but I still am not sure about what brand. Are some better than others, or is it all preference?
