Definition
Full-disk encryption scrambles nearly all data on a storage device so it cannot be read without the correct credentials if the disk is removed or stolen.
Real-World Example
If a encrypted laptop is lost, thieves cannot casually browse documents on the drive without the unlock PIN or key.
