GOAL:

What is Data Corruption

FIX:

Lost integrity, or the process of losing integrity. Data corruption can occur on two levels: physical and logical.

Physical corruption means the data itself has been inappropriately altered, for example, by a hardware failure causing a dropped or stuck bit that creates a value of 0 or 3 in place of a 1.

Logical corruption means different elements inappropriately get out of sync with one another, often because a multi-step operation was neither fully completed nor fully undone. No physical corruption is involved.
