Final answer:
The power-saving state for a computer not in use is known as sleep mode, which saves electricity and reduces wear on the hardware by turning off most components. It's an effective way to save power compared to keeping the computer fully on all day.
Step-by-step explanation:
The power-saving state for a computer when it is not in use is commonly referred to as sleep mode. Sleep mode is a power-saving state that allows a computer to quickly resume full-power operation (typically within several seconds) when you want to start working again. The computer achieves significant power-saving by turning off most of its hardware components, thus saving electricity and reducing wear and tear on the components.
Putting your computer to sleep is an effective way to save electricity when the computer is not in use for short periods. The energy consumption during sleep mode is far less compared to when the computer is fully on. For instance, if a computer is on for a whole day, it will use much more energy than if it were put to sleep after 10 seconds of inactivity.
