What command is typically used to remove a module from memory?

The command used to remove a module from memory is 'rmmod'. This command is essential in Linux systems for managing kernel modules, which are pieces of code that can be loaded and unloaded into the kernel upon demand. When you want to unload a module that's currently in use or one you no longer need, 'rmmod' effectively instructs the kernel to remove that module from the running system.

Understanding the role of kernel modules is crucial. They allow for dynamic loading and unloading of functionality without requiring a system reboot, which enhances flexibility and performance. Using 'rmmod' ensures that resources utilized by the module are freed, and any dependencies on the module are also adequately handled by the kernel.

Other commands related to kernel modules serve different purposes. For example, 'lsmod' lists the currently loaded modules, while 'insmod' is used to insert a module into the kernel. 'modinfo' provides information about a specified module, such as its version and author, but does not affect module loading or unloading.

In summary, 'rmmod' is the correct command to remove a module from memory, crucial for maintaining an efficient and properly functioning system.
