I was wondering what "loop" mean in this usage of mount:
mount -t iso9660 -o loop matlab.iso /media/cdrom0
Is it a type of device? What does this device type "loop" mean? Can I choose other device types for the iso file? Thanks!

A "loop" device in Linux is an abstraction that lets you treat a file like a block device. It's specifically meant for a use like your example, where you can mount a file containing a CD image and interact with the filesystem in it as if it were burned to a CD and placed in your drive.
