Modems are the devices that allow computers to communicate with a phone line or network. Technically speaking, a modem is a device that modulates an analog carrier signal to encode digital information, and also demodulates a carrier signal to decode the transmitted information. Ultimately, a signal is produced that can be transmitted easily and decoded to reproduce the original digital data (files, Web pages, and documents).
Older computer users may remember a time when dial-up modems were cutting-edge technology, but today, DSL and cable modems are quickly replacing them. These modern modems are capable of transmitting data back and forth at a much higher speed, which makes it much easier to efficiently browse the Internet and send emails.
Before buying a modem, you'll need to know how you'll be connecting to the Internet. Most popular today is the cable modem, which communicates through your cable provider's network. To learn more about modems, please visit the articles below.
