Answer:
The operating system (OS) keeps track of all the different hardware devices installed in the computer. It does this by collecting information from different sources, such as system firmware, device drivers, and hardware detection software. This information is then stored in a database called the Device Manager, which lists all the hardware devices installed on the computer.
The Device Manager allows users to view details about their hardware devices, including device names, manufacturers, driver versions, and more. It also provides a means for users to troubleshoot device issues, update drivers, and disable or uninstall devices that are no longer needed.
In summary, the operating system's built-in system architecture and mechanisms are responsible for keeping track of all the hardware devices installed in the computer, and the Device Manager provides users with an interface to view and manage this information.
