The term "DSL modem" is technically used to describe a modem which connects to a single computer, through an Ethernet port, USB port, or is installed in a computer PCI slot. The more common "DSL router" is a standalone device that combines the function of a DSL modem and a router, and can connect multiple computers through 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.
