What's the difference between broadband, high speed internet, and DSL? And which one requires a modem?

Question

Is there any kind of internet service that doesn't require a modem?

Answer 1

Broadband is the name given to a group of technologies which provide you internet access in excess of 256Kbps.

High Speed provides you access to speeds from 56-256Kbps..

DSL stands for Digital Subscriber Line. This technology is a part or one of the broadband technologies (Internet through Cable is another, or through Dish Antenna).

All of them would require a modem someplace. A modem converts the internet signals to one that your computer understands..
