Volume (computing) In computer data storage, a volume or logical drive is a single accessible storage area with a single file system, typically (though not necessarily) resident on a single partition of a hard disk. Although a volume might be different from a physical disk drive, it can still be accessed with an operating system's logical ...
Logical volume management. In computer storage, logical volume management or LVM provides a method of allocating space on mass-storage devices that is more flexible than conventional partitioning schemes to store volumes. In particular, a volume manager can concatenate, stripe together or otherwise combine partitions (or block devices in ...
Shadow Copy (also known as Volume Snapshot Service, [ 1] Volume Shadow Copy Service[ 2] or VSS[ 2]) is a technology included in Microsoft Windows that can create backup copies or snapshots of computer files or volumes, even when they are in use. It is implemented as a Windows service called the Volume Shadow Copy service.
The Logical Disk Manager ( LDM) is an implementation of a logical volume manager for Microsoft Windows NT, developed by Microsoft and Veritas Software. It was introduced with the Windows 2000 operating system, and is supported in Windows XP, Windows Server 2003, Windows Vista, Windows 7, Windows 8, Windows 10 and Windows 11.

A potentiometer is a three- terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. [ 1] If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat . The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential ...
