Broadband: DSL, Cable, T1

 

Broadband is often called high-speed Internet, because it usually has a high rate of data transmission. In general, any connection to the customer of 256 kbit/s (0.256 Mbit/s) or more is considered broadband Internet.

For home and some offices, DSL or cable broadband would be the appropriate choice, being affordable and easy to connect and configure. These type of connection have high download speeds (1.5 - 8.0 mbs) which is good for streaming music and videos, but on the downside the upload speed hovers around 512 kbs and dynamic IP addeess.
