The two types of recovery information mentioned in the text are Undo and Redo.

In database systems and other computing environments, recovery information is crucial for ensuring data integrity and consistency, especially in case of system failures or errors. The Undo operation allows the system to revert to a previous state by reversing the last action taken—this is particularly useful when a mistake is made, allowing users to recover from unintended changes.

On the other hand, the Redo operation permits the restoration of an action that had been undone, thus enabling users to reapply changes that were previously reverted. Together, these two mechanisms facilitate robust transaction management, spanning applications from database transactions to user interfaces, ultimately enhancing data reliability and user experience.
