Linux modules are lumps of code that can be dynamically linked into the kernel at any point after the system has booted. They can be unlinked from the kernel and removed when they are no longer needed. Mostly Linux kernel modules are device drivers, pseudo-device drivers such as network drivers, or file-systems.
How Modules are loaded in Linux?
Loading a Module
- To load a kernel module, run modprobe module_name as root . …
- By default, modprobe attempts to load the module from /lib/modules/kernel_version/kernel/drivers/ . …
- Some modules have dependencies, which are other kernel modules that must be loaded before the module in question can be loaded.
What does module load do?
Basically, the module command modifies your environment so that the path and other variables are set so that you can use a program such as gcc, matlab, or mathematica.
