What Is ADSL Cable?

Asymmetric digital subscriber line (ADSL) is a type of digital subscriber line technology, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. ADSL is asymmetric in that it uses most of the channel to transmit downstream to the user and only a small part to receive information from the user. Although the new fiber technology allows faster connection to the internet, ADSL is still a popular choice because of its flexibility. ADSL broadband is an extremely cost effective way to access the internet and is the most useful for startups and small businesses who have low reliance on the technology.
