The main reason to use secondary storage is to hold data for long periods of time, even when the power supply to the computer is turned off.
True
False
Answer:
Explanation:
True. The main reason to use secondary storage is to hold data for long periods of time, even when the power supply to the computer is turned off. Secondary storage devices, such as hard drives and solid state drives, are used to store data that is not currently being used by the computer but needs to be kept for future use. These devices retain data even when the computer is powered off, unlike primary storage devices such as RAM which lose their data when the power is turned off.
Secondary storage is also used for archiving older files and data that are not needed on a regular basis. They also provide a larger storage capacity than primary storage devices, which allows users to store more data or larger files. With the availability of large external storage devices, like hard drives or USB drives, it's possible to take the secondary storage outside of the computer, making it easy to backup or share data.
