The Standard 2400 bps modem is an older, low-speed dial-up modem that operates at a maximum data transfer rate of 2400 bits per second (bps). This type of modem was commonly used in the 1980s and 1990s for connecting to the internet or remote systems over phone lines before broadband became widespread. These modems are typically external devices that use a serial (RS-232) or USB connection.

In modern versions of Windows, especially on newer systems, the Standard 2400 bps modem may not have a dedicated driver, as most modern modems use higher speeds. However, older versions of Windows (e.g., Windows 95, 98, XP) would typically have built-in generic drivers for older dial-up modems.
