When you save to secondary storage device, your data will remain intact even when the computer is turned off.

Explanation:
Secondary storage devices are hardware devices that are used to store and retrieve data on a long-term basis. They are non-volatile, which means that the data stored on them remains intact even when the power is turned off. This is in contrast to primary storage devices, such as RAM (Random Access Memory), which are volatile and lose their data when the power is turned off.

Here are the reasons why secondary storage devices are the correct answer:

1. Non-volatile nature: Secondary storage devices, such as hard disk drives (HDDs) and solid-state drives (SSDs), are designed to retain data even when the power supply is turned off. This is because they use magnetic or flash memory technology to store data, which does not require constant power to maintain the stored information.

2. High capacity: Secondary storage devices typically have much larger storage capacities compared to primary storage devices. This allows users to store large amounts of data, such as documents, images, videos, and applications, for long-term use.

3. Persistence: When you save data to a secondary storage device, it remains on the device until it is intentionally deleted or overwritten. This is different from primary storage devices like RAM, where the data is stored temporarily and gets erased when the power is turned off or the system is restarted.

4. Portability: Secondary storage devices are often portable, which means that you can easily disconnect them from one computer and connect them to another. This allows you to access your data from different devices and locations, making secondary storage devices suitable for backups and data sharing.

Overall, secondary storage devices provide a reliable and persistent solution for storing data, ensuring that your information remains intact even when the computer is turned off.
