ADSL — Asymmetric Digital Subscriber Line is a technology for transmitting digital information at a high bandwidth on existing phone lines to homes and businesses. ADSL is asymmetric in the sense that it uses most of the channel to transmit downstream to the user and only a small part to receive information from the user. This means, high download rates and slower upload rates. Generally if you see 2Mb ADSL broadband, it refers to 2 Mbit/s Max d/load rate. The upload rate will probably be around 256 kbit/s Max. (ADSL has a maximum download rate of 8 Mbit/s, ADSL2 is capable of up to 16 Mbit/s and ADSL2+ is rated at 24 Mbit/s maximum.)
Cable modem — Primary competitor to ADSL, uses digital information transmitted over a cable television infrastructure.
Dial-up — A method of connection to the internet using existing copper phone lines using a modem on the client's end to send information at a slow speed, normally reaching maximum speed at about 56 kbit/s. This technology uses the voice spectrum of the telephone lines to transmit data using a system of sounds that only the receiving modem or ISP understand.
