DSL Modem - phone line - USB/RJ45 cable - NIC/USB interface on your
computer
A dialup modem and DSL modem are separate pieces of hardware and will
normally not be used together (although they could).
DSL modems come in two flavors - USB and Ethernet (sometimes called RJ-45 or
Cat5 or Cat6). I'd avoid the USB variety. Stick with Ethernet.
So you'll want a Ethernet DSL modem. The hookup goes:
PHONE <-> DSL MODEM <-> OPTIONAL ROUTER <-> NIC <-> PC
You'll need a router to hook up multiple computers. There are other ways to
do this, but generally the router is the quickest, least quirky way. A
router also provides some buffer for security. It's optional if you're only
going to hook up one computer and don't mind having it directly on the net.
The router can offer other features like 802.11 wireless connections. The
phone company won't include this equipment btw but a simple router only
costs $30.00.
Most computers sold in the past five years will have a network interface
card. This is what the ethernet cable plugs into. If your computer doesn't
have a NIC, you'll need to buy one. $10.00. You may need an ethernet
cable. One should come with the DSL modem.
That's basically it. You can get a lot of info at dslreports.com (last I
checked).
