ADSL (Asymmetric Digital Subscriber Line)

ADSL is an acronym that stands for Asymmetric Digital Subscriber Line. It refers to a variant of DSL as a broadband connection technology. Unlike DSL, data uploads to the Internet are transmitted at a slower speed than downloads from the Internet. ADSL can be used on both analog and digital telephone connections. In principle, an ADSL connection consists of two modems that are connected to a telephone line and connected with the computer by means of a USB interface or network card.
