Mechanism Report on Cable and DSL Modems
Cable modems link to the computer via Ethernet, which makes the service online all the time. However, Ethernet is a shared medium, and the speed will vary depending on how many customers on that cable segment are using the Web at the same time. Just like a cable modem, DSL provides "always-on" operation, which is great because your phone lines are free and there's no dial-up. DSL being a new technology is very much advanced, that's why special representatives are needed to handle problems or installation. If a user lives far away from the station the service will be poor unlike someone who lives closer. The representatives might need to fix your wiring up also. That and the speed is pretty much the difference between cable modems and DSL modems. Another negative thing about cable modems are some cable operators are strict about running a server. The purchase of an Ethernet card is required as well. Internal modems can't be used with Macintosh; also expensive upgrades may be required. Some areas don't even offer service, which goes for the DSL service also.
