Networks

DSL or Broadband are the same. ADSL is a type of DSL where the upstream and downstream speeds differ (hence the "asymmetric" part (ADSL). There are many variations of DSL technology for different types of application (HDSL, SDSL, IDSL etc).

DSL and ADSL are both the same kind of connection. The difference being the upload / download speed. ADSL the download speed is faster then the upload speed. The both use a phone line for the connection.

DSL is a whole group that includes ADSL, SDSL, etc.

Broadband is thought of as just a high speed internet connection rather than a dailup modem.

Broadband includes Cable, DSL, t1, and t3 connections.

DSL is the generic term for a Digital Subscriber Line.

Broadband is a generic term for any connection to the internet that is significantly faster than dial-up.

ADSL stands for Asynchronous DSL.
With an ADSL connection, your upload speed is slower than your download speed.
Often by a factor of 10 or more.

SDSL stands for Synchronous DSL.
With a SDSL connection, your upload and download speeds are the same.

ADSL is typically used for home and businesses that only need to access information on the web.

If you are running e-commerce or need to upload a lot of data to the web, you may want a SDSL connection.

SDSL is also a better choice if you want to set up remote access such as peer to peer networking.
