Computer and Internet (Q&A)

Answer:

It stands for Asymmetric Digital Subscriber Line. It is a form of the DSL - Digital Subscriber Line technology. ADSL data communications technology enables faster data transmission over copper  telephone lines than a conventional voice-band  modem can provide. It does this by utilizing frequencies that are not used by a voice telephone call. A splitter - or micro-filter - allows a single telephone connection to be used for both ADSL service and voice calls at the same time. DSL (SDSL) uploads and downloads data at the same speed, ADSL has different maximum data transfer rates for uploading and downloading data.For example, an ADSL connection may allow download rates of 1.5Mbps, while upload speeds may only reach 256Kbps. Since most users download much more data than they upload, this difference usually does not make a noticeable impact on Internet access speeds. However, for Web servers or other computers that send a lot of data upstream, ADSL would be an inefficient choice.
