What is the difference between adsl and broadband?

Broadband which is also most commonly refered to various forms of DSL (Digital Subscriber Line) (or known as xDSL where x represents the many forms it has) vary from ADSL which is one of its various forms only by the uploading speed.

ADSL refers to the term "Asymmetric Digital Subscriber Line". Through its name itself it implies that the connection is asymmetric, meaning that the uploading speed and downloading speed differs from each other. In ADSL the uploading speed is much lower than the downloading speed where as in broadband (or DSL) the uploading speeds and down loading speeds are very much the same.

When considered in terms of price DSL connections fetch a higher price in the market compared to ADSL connections simply due to its higher uploading speed. ADSL connections are best applied in situations where there is a high demand for downstream data than upstream data but is not suitable for interactive systems that require data to be transferred both ways (upstream and downstream). For such cases DSL is the most suited.
