What does LVM stand for in Linux?

LVM stands for Logical Volume Manager in Linux. It is a device mapper that provides an abstraction layer on top of physical storage devices, allowing for the management of disk storage more dynamically and flexibly compared to traditional partitioning methods. With LVM, you can create logical volumes that can span across multiple physical disks, adjust the size of these volumes on-the-fly, and facilitate tasks like snapshots and resizing without significant downtime.

This technology improves disk space management by allowing administrators to easily allocate or reallocate storage as needed, which is particularly beneficial in environments where workloads can change frequently. It supports various functionalities like dynamic resizing of volumes, creating snapshots for backups, and pooling storage from multiple disks into a single volume group, providing versatility and efficiency in storage management.

The other options refer to concepts that are not relevant in this context, such as memory management techniques or virtualization platforms, which do not apply specifically to the storage management capabilities offered by LVM in Linux.
