What is a Linux device driver?

Linux device drivers are specialized software components that allow the Linux operating system to communicate with hardware devices, such as network cards, storage drives, or input devices. These drivers translate generic OS instructions into device-specific operations, enabling the hardware to function correctly with Linux. They are typically written in C and integrated into the kernel, either as part of the core kernel or as loadable modules. Developing and maintaining device drivers is crucial for hardware compatibility and system stability.
