What type of operations does udev handle related to device management?

Udev is a device manager for the Linux kernel that plays a crucial role in handling events related to device management. It is specifically designed to manage the dynamic creation of device nodes in the /dev directory when devices are added or removed from the system. This means that when a hardware device is connected or disconnected, udev takes action by responding to those events, which involves creating, modifying, or deleting device files as necessary.

The role of udev encompasses a variety of tasks that are centered around responding to events rather than performing functions like data processing, input validation, or resource allocation. While these can be important in the broader context of system operations, they are not the primary focus of what udev does. Instead, udev's function is about detecting changes in hardware and managing the associated device files in real-time, ensuring that the appropriate actions are taken to reflect the current state of devices in the system. This event-driven nature is what makes udev an essential component of modern Linux systems.
