What Does Mount Mean?
Mount, in computing, is used to define the process of adding additional storage or other devices to a computing system. Whenever a mass storage device like a disk drive or flash drive is made available to the existing storage, it needs to be mounted on the system. For instance, inserting a CD is called mounting and installing the disk drive for a device is also known as mounting. Only after a device has been mounted, can the computer access it.
Techopedia Explains Mount
Mounting can be defined as the software process that activates a particular disk by making its content available to the computer’s file system. Mounting creates a partition for the mounted device in the computer’s file system. Even after a physical connection is made between a device and the computer, if the device is not mounted, the computer is not able to recognize it.
