A Smart Link 56K Modem Device refers to an external or internal dial-up modem produced by Smart Link that allows computers to connect to the internet via telephone lines using a 56Kbps (kilobits per second) connection. Despite the widespread use of broadband and wireless internet today, 56K modems were common in the past for dial-up connections, especially when high-speed internet was not available.

A Windows driver for this modem is the software that enables the operating system (Windows) to interact with the modem hardware, allowing you to use it for connecting to the internet, sending faxes, or other tasks requiring dial-up communication.
