What is Linux Device Driver?

A Linux device driver is a software module that enables the operating system to interact with a specific hardware device. It acts as a translator, converting generic OS commands into device-specific instructions. Device drivers are crucial for making hardware components like printers, network cards, storage devices, and graphics cards functional within the Linux environment. They are often implemented as kernel modules that can be loaded and unloaded dynamically, and they follow a specific API defined by the Linux kernel.
