The Agere Win Modem is a type of software modem produced by Agere Systems (a division of LSI Corporation), often used in older desktop or laptop computers for dial-up internet access. These modems were commonly included in computers before broadband internet became widespread. The "Win Modem" refers to the fact that the modem relies on the computer's CPU and operating system (Windows, in this case) for processing, rather than having dedicated hardware to perform all the functions of the modem.
