Broadband Services - Dial-up Service

Dial-up access uses a device called a modem (Modulation-Demodulation) that makes use of the telephone wires to transmit the information data. The fastest speed that a dial-up modem can receive and transmit data is about 56Kbps (Kilo bits per second) - that's 56,000 bps.

As the Web slowly grew to what it is now, by supporting animation, video and voice,Dialup service was not efficient ,then came Broadband service which allowed 10x the speed of dial-up access over the same telephone line.

The most common technology the telephone companies used to deliver broadband service to the home is called DSL (Digital Subscriber Line), which comes in different forms like ADSL or SDSL. In either case, it's still based on the DSL technology.
