Definition - What does Host-Based Modem mean?

A host-based modem is also known as a winmodem.
Techopedia explains Host-Based Modem
Some host-based modems included controller software, allowing for multiplatform modem use. However, the majority only include Windows operating system software (winmodems) and could not be used with any other OS. In addition, locating host-based modem drivers for other OS types was practically impossible.
Host-based modems included easily-upgradeable drivers that also upgraded the firmware. However, most host-based modems were known for slowing down computer processing and creating additional issues.
