A loadable kernel module (LKM) is an executable library that extends the capabilities of a running kernel, or so-called base kernel, of an operating system. LKMs are typically used to add support for new hardware (as device drivers ) and/or filesystems , or for adding system calls .
lsmod is a command on Linux systems that lists each loadable kernel module that is loaded.. Example output from lsmod: .

The character between the address and the symbol (separated by spaces) is the type of a symbol. The nm utility program on Unix systems lists the symbols from object files. The System.map is directly related to it, in that this file is produced by nm on the whole kernel program – just like nm lists the symbols and their types for any small object programs.
All device drivers, file systems, etc still run in kernel mode, just like in a monolithic kernel (see hybrid kernel). And how exactly are Windows's loadable kernel drivers different from LKM? The fact that Windows doesn't call them "kernel modules" doesn't mean it doesn't have a similar concept.
A NetWare Loadable Module [1] [2] [3] (NLM) is a loadable kernel module (a binary code module) that can be loaded into Novell's NetWare operating system. NLMs can implement hardware drivers, server functions (e.g. clustering), applications (e.g. GroupWise ), system libraries or utilities.
The proc filesystem (procfs) is a special filesystem in Unix-like operating systems that presents information about processes and other system information in a hierarchical file-like structure, providing a more convenient and standardized method for dynamically accessing process data held in the kernel than traditional tracing methods or direct access to kernel memory.
Navigate through the kernel features and menuconfig commands. Esc+Esc: Exit menuconfig or cancel the command. ↵ Enter: Activate a command, or expand a branch. y: Compile and include this feature inside of the kernel. m: Compile this feature as a module, separate from the kernel. n: Do not compile the feature. / Search configuration parameter.
Linux portal; This category contains articles documenting various Linux kernel features. Most features in the Linux kernel can be compiled as loadable kernel modules, or can be statically linked into the kernel binary. For features that are bundled separately from the Linux kernel, please see Category:Third-party Linux kernel modules.
