What Is a DSL Modem?

A DSL (digital subscriber line) modem is a device that serves to facilitate the connection of a computer to the internet. A DSL modem gives speedy access to the internet because it is specifically designed for use with a DSL internet connection. A DSL connection is a much better internet service than dial-up not only because of speed but because of the ability to use the telephone at the same time as surfing the net.

The DSL modem, which is also similar to an ADSL (asymmetric digital subscriber line) modem, basically performs the same function as a dial-up modem, but with a few marked differences. For example, DSL modems are always an external device that is connected to the USB or Ethernet port, whereas dial-up modems can be internal devices attached directly to the computer’s motherboard.
There are some DSL modems that have the capability to be attached to either the USB port or Ethernet port. But experts are one in saying that connection to an Ethernet port is the best option because of provides a better connection.

An Ethernet-connectible DSL modem is also a bit more flexible than a USB-connectible DSL modem because it can be used not just by a single computer but also a network of computers. By using a router, the DSL connection can be shared to more than one computer. As long the router can support NAT or Network Address Translation, sharing the connection is easy. In the long run, it is a better option because it saves on money when a connection is shared in the house.
