EXPLANATION
dmesg (Display message or driver message) is a command
which will show Kernel ring buffers. These messages contain valuable
information about device drivers loaded into the kernel at the time of
booting as well as when we connect a hardware to the system on the fly.

driver is loaded into the kernel. These messages are helpful in
diagnosing or debugging hardware and device driver issues
