Which option is not part of managing IRQs in the Device Manager?

1. View IRQ assignments

2. Change IRQ settings

3. Uninstall a device driver

4. View resources by type

The correct answer is: Uninstall a device driver

The option that is not part of managing IRQs in the Device Manager is related to the uninstallation of a device driver. Managing IRQs (Interrupt Request Lines) primarily involves viewing assignments, changing settings, and viewing resources associated with devices. Specifically, viewing IRQ assignments allows users to see which devices are using which IRQs, while changing IRQ settings can help resolve conflicts when multiple devices attempt to use the same IRQ. Additionally, viewing resources by type enables users to examine different resource settings, such as memory addresses and I/O ports, used by devices. In contrast, uninstalling a device driver is not directly related to IRQ management. While this action can remove a device from the system and potentially free up its IRQ, it does not involve the direct management of IRQs themselves. The focus of IRQ management is on monitoring and configuring how devices communicate with the CPU, rather than the act of removing drivers.
