What is ADSL?
ADSL stand for asymmetric digital subscriber line, here
asymmetric means data speed does not same in both directions
(upload and download) and
provides high speed on already exiting telephone lines and
same time you can use internet and as well as your line for
phone. It is faster than DSL and but ADSL downstream speed (downstream
rate
) is different with upstream speed (sending
rate
).
ADSL is much easier to install and provides much faster data
transfer rate. ADSL support data upstream rate is 16 Kbps to
640 Kbps and data downstream rate is 1.5 to 9 Mbps. Normally
ADSL and download and upload speed is averagely 10 time more
than a normal dial up connection.
Your DSL connection to the Internet will always on, there is
not need to dial your ISP each time to use internet
and the main requirement for ADSL connection is modem. There
are many option in modem hardware for example:
USB ADSL Modem, PCI ADSL
Modem, and ADSL Router, but mostly used USB Modem because
easy to install. For 1 or 2 computer the USB modem is best
but for more than 3 computer you should use Ethernet ADSL
modem.
ADSL
connections are more useful in applications like
videoconferencing, to run online movies and upload and
download heavy files. This connection is ideal for today
business requirements.
