A volume may refer to any of the following:

Speaker volume controls

1. When referring to sound, volume refers to the amplitude of the sound being projected from a speaker. The picture shows two knobs that change the volume level: one controls the subwoofer, and the other controls the main (overall) sound volume. To increase the sound level, turn the knob to the right or clockwise. To decrease the sound level, turn the knob to the left or counterclockwise.

2. When referring to data storage, a volume refers to a logical drive (e.g., hard drive), which has a single file system and is usually on a single partition. For instance, on a typical Microsoft Windows computer, the volume named C: contains the operating system. In Windows, any drive which has an assigned drive letter is a volume.
