Mounting is a process in which the operating system adds the directories and files from a storage device to an empty directory, so the user can access the data through the system file manager.

Storage systems can be internal hard disks, external hard disks, USB flash drivers, SSD cards, memory cards, network-attached storage devices, CDs and DVDs, remote file systems, or anything else.

Terms:

Device name - The identifier given to a storage partition.

Mount point - The empty directory in which we are adding the file system during the process of mounting.

Commands

# Mounting a partition
sudo mount /dev/sda1 /mnt

# Mounting a USB drive
sudo mount /dev/sdb1 /media/usb

# Unmounting
sudo unmount /mnt
