What is a disadvantage of cloud storage relating to internet requirements?

The reason why cloud storage being unusable without internet is a significant disadvantage is that cloud storage solutions depend entirely on internet connectivity for access to files and data. When users store their information in the cloud, it resides on remote servers, meaning that to retrieve or interact with the data, an internet connection is essential. If the internet goes down or if a user is in an area with no internet access, they cannot access their files. This reliance on connectivity can lead to frustrations, especially during times of connectivity issues, natural disasters, or when traveling to areas with limited internet service.

In contrast, other options discuss aspects that do not accurately reflect the primary disadvantage associated with the internet requirements of cloud storage. For instance, cloud storage is not accessible without an internet connection, and while some services enable offline access to certain files, this does not reflect on the core use of cloud storage in real-time. Therefore, the key drawback remains the complete inability to access files without an online connection.
