    What are device drivers on Linux?

    The software that manages or manages a hardware controller is called a device driver. Linux kernel device drivers are essentially a shared library of memory-resident, privileged, low-level hardware management routines. It is the Linux device drivers that handle the specifics of the devices they manage.
