Modems
The purpose of a modem is to change data from digital form to analog form. These data then passes through a phone line to the computer. A modem was named as such because it performs both the modulating and demodulating of data signals. There are computers which already come equipped with a modem, although there are instances wherein you would have to purchase one, either when your computer doesn't have an internal modem, or when you want a broadband Internet connection but you only have a standard modem.
A broadband modem is different from a dial-up modem. When you first sign up for a broadband service, your Internet service provider will most likely offer you with a modem along with the package you want. Accepting this offer, even if they're asking for extra payment for it, will be a safe thing to do because you'll be sure that the modem you're going to have is supported by your provider and will work fine with your Internet setup.
If your provider does not offer you a modem, then you can purchase a modem of your own. Before you go ahead and buy one, it's important that you ask your provider first about the kind of modem that will suit your Internet connection and computer. Some types of modems are cable and ADSL, each of which differ in bandwidth and speed capacity. If you wish to know which kind of modem will be right for your needs, you can consult with experts or browse through the links found on this site to find the modem which will be right for you.
