A modem is a device that connects your computer to the internet by sending data back and forth through it. If you computer doesn't have a modem, it might be able to connect through wireless or by Ethernet.

A modem is most used to transfer data between your computer and other computers (most commonly on the Internet) using your phone line. Modems have a much slower data transfer rate than a Local Area Network (LAN), and these days (with prevalent high speed LAN connections) are not commonly needed.

The modem enables you to go online using the phone system. If your computer is a new model and has no modem, then the expectation is that you will buy one, after you determine what kind of Internet service you want to get. The kind of modem you need is determined by your ISP.
