Mounting refers to connecting one external device with another. This is helpful in tasks like backup, extending the storage space, and volume mounting. In this article, we will look into the mount command along with its examples.
What is Mounting of FileSystem
Mounting implies connecting your external drive to your computer so that your operating system can identify it and execute data processing with the disc straight away. If you can locate your drive in your operating system's file explorer, it implies it is "mounted." If you have worked with containers, you might have used this command when mounting volumes of containers. The concept of mounting here remains exactly the same as in containers.
