DSL Modem
A digital subscriber line (DSL) modem is a device used to connect a computer or router to a telephone line which has the digital subscriber line service configured, to allow the computer to connect to the Internet. Put simply, a DSL modem or DSL router is what is needed in order to connect to DSL broadband.
The term DSL modem is technically used to describe a modem which connects to a single computer, through a USB port or is installed in a computer PCI slot. The more common DSL router which combines the function of a DSL modem and a home router, is a standalone device which can be connected to multiple computers though multiple Ethernet ports or an integral wireless access point. Also called a residential gateway, a DSL router usually manages the connection and sharing of the DSL service in a home or small office network.
