Final answer:
Sleep mode and hibernation mode are designed to save time when resuming work on a computer.
Step-by-step explanation:
The two modes that store the current state of all open programs and documents and are designed to save time when you resume working on the computer are sleep mode and hibernation mode. Sleep mode and hibernation mode are designed to save time when resuming work on a computer.
Sleep mode allows the computer to quickly resume its full power state when activated, while hibernation mode saves the current state of the computer to the hard drive and then shuts down completely. When the computer is powered on again, it restores the saved state, allowing users to get back to work quickly.
