Final answer:
A second hard drive is useful for providing additional storage space and acts as a backup to reduce the risk of data loss. Students can install an internal hard drive or use an external hard drive as a solution.
Step-by-step explanation:
A second hard drive is useful because it provides additional storage space for the computer. This allows the user to store more files, such as documents, pictures, videos, and applications. It can be particularly helpful for people who work with large files or who need to keep their files organized and separate from the main drive.
Having a second hard drive also reduces the risk of data loss. In case the primary hard drive fails, the data stored on the second hard drive remains safe. It acts as a backup, ensuring that important files are not lost.
If a student is considering adding a second hard drive to their computer, the solution would be to either install an internal hard drive inside the computer or to use an external hard drive. An internal hard drive requires installation inside the computer's case, while an external hard drive connects to the computer using a cable.
