Though relatively inexpensive and widely available, the long 'dial-in' process, slow transmission speeds, and dropped connections are sending residential users looking elsewhere from frustration. Analog modems are not designed to handle the communications of a business LAN, and should be used only in the rare cases when no other technology is available.
Cable modems connect via the cable TV network connection in a residence.
Theoretical maximum speed is limited by the Ethernet board at 10Mbps. However, actual maximum speed is typically 1-3Mbps. Cable connectivity suffers from security holes and is unsuitable for hosting servers. Therefore, cable connectivity is not a viable business solution. ADSL is a good solution for the residential user who wants high speed Internet connectivity but doesn't want the expense of additional phone lines.
