ADSL stands for Asym­met­ric Dig­i­tal Sub­scriber Line. This refers to the abil­ity to trans­mit data at a high speed/ band­width through cop­per pairs from the lo­cal ex­change to nearby street cab­i­nets.

The ADSL is an asym­met­ric sys­tem in the fact that it pri­ori­tises down­stream data as op­posed to up­stream data. This makes it a pop­u­lar sys­tem for in­ter­net users who want to down­load things from the in­ter­net.

This re­flects the na­ture of most in­ter­net users who want to ac­cess more in­for­ma­tion/data from the web than in­for­ma­tion/data they pro­vide.

This does mean that it could have lim­it­ing im­pli­ca­tions for busi­nesses that re­quire faster up­load speeds.
