Forgive me for posting such an imbecilic question, but I really am ham-fisted when it comes to technology. I've just purchased a new iMac, 20-inch, one of the new intel ones. I have moved from a much older iMach, you know - the one with the semi-spherical base from which protrudes a silver arm on which the monitor is mounted. This one is connected to the net via a USB socket into which plugs a speed touch 330 modem, which in turn goes via a phone to the phone socket, and bingo - internet connection. That appears not to be the case with my new computer, but the manual that comes with the computer is spectacularly lacking in information. It tells me I need an ethernet cable - fine, but it doesn't tell me what this then plugs into and how it connects to the phone line to get my my connection. Can anyone tell me in plain language what I need? Thanks
