Once you attach a device to your system such as a USB, especially on a desktop, it is automatically mounted to a given directory, normally under /media/username/device-label and you can then access the files in it from that directory. However, this is not the case with a server where you have to manually mount a device and specify its mount point.

Linux identifies devices using special device files stored in /dev directory. Some of the files you will find in this directory include /dev/sda or /dev/hda which represents your first master drive, each partition will be represented by a number such as /dev/sda1 or /dev/hda1 for the first partition and so on.

$ ls /dev/sda*
