Software modems are cheaper and use less power than hardware modems, but can slow down a computer’s performance and have compatibility issues. They rely on the computer’s processor and can be easily updated. They are identified by requiring a specific operating system or processor and can only be run under Windows®.
A software modem is a low-cost alternative to a standard hardware-based modem. While hardware modems contain all the parts needed to connect to the Internet, the software version transfers some of that work to the computer’s processor.
Modems have two main components: the controller configures and dials the modem, and the datapump sends and receives data. Depending on the type of software modem, the controller or data pump or both may be replaced by software.
Because it has fewer parts, a software modem is typically much less expensive than a hardware modem. Most modern personal computers have one built-in. It also requires less power than a standard modem, which can be a boon for someone using a laptop that runs on battery power. They can also be easily updated by simply updating the software driver. And in the past, these modems could only be used for dial-up connections, but a DSL software modem is now an option.
However, the software modem has often been criticized for its drawbacks. Because it relies on the computer to perform many of its processes, it can be a drag on a computer’s processor, leading to slow performance or disconnections. This can be especially concerning for people who play online, because computer resources can be too low between the game and your Internet connection. And due to its dependence on software, the modem can become damaged or conflict with other software. On older computers or non-Windows® computers, there may also be compatibility issues.
It’s generally not too difficult to identify a software modem. If a modem specifically requires a certain operating system or processor, it’s probably a software version. And they typically can only be run under Windows®, so modem names containing the word “Win” can be a red flag.
