What is the name of the feature that allows a user to revert a computer's system files, settings, and installed applications to a previous, healthy state?
System Restore Point
What is the name for the thin, long-short-long line used to indicate the exact center of a circle, arc, or symmetrical object?
Center Line
What type of drawing provides multiple two-dimensional views (like top, front, and right side) of an object, aligned with each other?
