What is the method of accessing the Internet with a theoretical bandwidth of 56kbps?

The way to access the Internet is "telephone dialing". Telephone dial-up Internet access is the most commonly used and common way to connect to the international Internet through telephone lines and Internet-specific equipment (modems) and computers. Modems are the dial-up methods for personal computers to access the Internet. Most of the equipment that must be used when using 33.6Kbps or 56Kbps Modem.
