Where are Linux drivers?
Many Drivers come as part of the distribution’s Kernel. Use Them. These Drivers are stored, as we saw, in the /lib/modules/ directory. Sometimes, the Module file name will imply about the type of Hardware it supports.

- Some modules have dependencies, which are other kernel modules that must be loaded before the module in question can be loaded.
What are Lib modules?
The /lib directory contains kernel modules and those shared library images (the C programming code library) needed to boot the system and run the commands in the root filesystem, ie. by binaries in /bin and /sbin. Libraries are readily identifiable through their filename extension of *. so.

How do kernel modules work?
Kernel modules are pieces of code that can be loaded and unloaded into the kernel upon demand. They extend the functionality of the kernel without the need to reboot the system. To create a kernel module, you can read The Linux Kernel Module Programming Guide. A module can be configured as built-in or loadable.
How do I know if Linux kernel is updated?

The OS sits between applications and hardware and makes the connections between all of your software and the physical resources that do the work.
Does Linux automatically find drivers?
Your Linux system should automatically detect your hardware and use the appropriate hardware drivers.
Will Windows drivers work on Linux?
Drivers are an integral part of your computer. … If you’re using the Linux operating system, you’ll quickly find that not a lot of devices that were meant for Windows have Linux device drivers. You can, however, quickly convert a Windows driver to Linux by installing a program called NDISwrapper on your computer.
What are modules in Linux?
What are Linux modules? Kernel modules are chunks of code that are loaded and unloaded into the kernel as needed, thus extending the functionality of the kernel without requiring a reboot.
