What does Persistence mean for USB Linux Users?
For USB Linux users, a persistent Linux install is one that allows it's user to save data changes back to the USB storage device instead of leaving the information in system RAM. This data can then be recovered and used again on subsequent boots, even when booting from different machines. Typically a separate Persistent storage space (persistent overlay) is used in conjunction with a compressed Live Linux OS. - Source
