How do I tell what kind of modem my computer uses?

If you have broadband Internet access through an Internet service provider (ISP), you most likely have a broadband modem. The modem is usually connected to a cable or Digital Subscriber Line (DSL) and is then connected to your computer through an Ethernet cable and network adapter.

Most newer computers no longer come with a dial-up modem. Many older computers have dial-up modems, which connect to the Internet by dialing a telephone number over a telephone line.
