The term ‘broadband’ is
generally described as a permanent high-speed network connection
with data speeds in excess of 128 kilobits
per second (Kbps). There are different types of broadband connections
available from different telecommunications companies and internet
service providers. An example would be cable internet, which uses
the same coaxial cables that carry cable-television signals. Another
is Wireless or WiFi, also technically referred to as 802.11, which
allows for anywhere surfing up to hundreds of meters using a wireless
network card and a wireless network base station.
are ultimately tied to the phone line, the quality and the age
of the lines determine your actual data mileage for your
connection. Broadband, on the other hand, allows for simultaneous
use of a voice connection and a data connection at the same time
(for example, digital subscriber lines or DSL). Analog telephone
lines were never meant to carry large data transfers effectively,
and is designed purposely for voice communication. On one end,
a phone coverts audio into electrical signals and converted back
audio at the other end. Some broadband connections do away with
the phone wires completely so that more than one type of data communications
service can be used at a single location.
A common denominator
in almost all broadband connections is being always readily available;
as long as the computer is turned on,
so is the internet. This is reffered to as an always on connection.
No more fiddling with dozens of telephone numbers, and no more
this is one of the basic advantages of using broadband.
that may still determine the choice of upgrading to broadband
from dial-up is the price. Broadband connections are
more expensive than a typical dial-up account. Price, however,
becomes trivial for the heavy bandwidth user since broadband
cheaper in the long run when you consider the amount of data
that actually goes through the connection as compared to dial-up.
