DSL stands for Digital Subscriber Line. It is a service that makes
the use of existing copper telephone wires for delivering data services
at extremely fast speed rates. It does not hamper the existing telephone
line. You can surf the Internet and talk on the phone, simultaneously.

56Kb dial-up connection. It is an always-on type of connection. This
implies that websites would load quickly, downloads would be faster,
buffering of videos would be fast and smooth and the domain of Online
games would be illimitable.
Based on the types of service, DSL can be can be categorized in three
divisions which are ASDL, IDSL and SDSL.

speed of 1.5 Mbps and upload speed of 384 K. In order to acquire a ADSL
connection, your location has to be within 3 miles of your local
telephone office. Also, a DSL router is needed for this type of
connection.
IDSL is a ISDN Digital Subscriber Line service which requires an ISDN
router. It provides a connection speed of 144 K. in this type of
connection distance is not a component to be considered.
SDSL means Symmetric Digital Subscriber Line. The speeds available under
this type of DSL connection depends on the distance between your
location and your local telephone office. The speed of downloads and
uploads can go up to 1.1 Mbps.

line to connect to the Internet. It provides extremely fast connection.

get hanged. It depends on the number of users accessing that particular
service. But, in a DSL connection there is no such problem. The speed of
DSL is consistent and high. This does not allow any kind of conjunction

connections. The popularity of DSL has risen to new heights which has
resulted in disconnections and up gradations of the cable modem
