What are the
primary types of high-speed Internet access?
The most common methods for
providing broadband Internet access are via
coaxial cable (TV cable) and ADSL (Asymmetric
Digital Subscriber Line). Less widely used
methods are via satellite, wireless networks and
by using variations of DSL such as SDSL
(symmetrical DSL), HDSL (High bit-rate DSL) and
VDSL (Very High Data Rate DSL).
What is ADSL?
ADSL or Asymmetric Digital
Subscriber Line is the technology that has been
developed for enabling broadband connections
using existing telephone networks. The telephone
exchange must be able to supports this
technology and the subscriber must use an ADSL
modem to connect to the Internet via a standard
telephone line.
What is high-speed
cable Internet service?
Cable Internet service uses the
same coaxial cable that is used for television
to provide high-speed Internet access. The cable
company must be set up to deliver this service
and the subscriber must have a special cable
modem to connect the computer to the cable
outlet.
What is satellite
Internet service?
There are two types of
satellite services – one that provides two-way
service that transfers data in both directions.
This method, however, is very expensive. A
cheaper option is a one-way service that is
comparable to cable or ADSL in terms of monthly
charges but uses a dial-up connection to upload
content. High-speed Internet access via
satellite is available world-wide. It is of
particular interest to people in remote
locations where ADSL and cable options are
unavailable.
What is wireless
Internet service?
A high-speed connection to the
Internet can be established using wireless
technology. A receiver on the outside of the
house sends the signals to connection points
inside your home. These in turn send the data
through to your computer.
