DSL modem - Computer Definition
A device used to connect a single computer or a network to a telephone company digital subscriber line (DSL) service for Internet access. Compared to analog dial-up, DSL significantly increases the bandwidth between the user's computer and the Internet. Download speeds have reached 10 Mbps and beyond, but the connection is asynchronous. In order to prevent users with lower-cost cable access from hosting high-traffic Web servers, the upload speed is approximately 10 times slower. Like cable Internet providers, telephone companies routinely change the user's IP address to prevent Web hosting (see DDNS). Connect Via Ethernet or USB DSL modems typically connect to the computer or network router via an Ethernet port; however, some DSL modems have a USB port for hookup to the computer but not the network. See DSL and cable/DSL gateway.
