What is cloud storage?

Cloud storage refers to online storage solutions that enable users to save and access files over the internet from any device connected to that same internet network. This type of storage allows for greater flexibility and convenience, as files can be accessed remotely without needing to be stored on local devices. Users can upload, store, and share their data safely while often benefiting from features such as automatic backups, security encryption, and easy scalability according to their storage needs.

The other options refer to different forms of storage that do not provide the same level of remote accessibility or internet-based functionality that cloud storage does. For example, physical storage of data in local devices restricts users to access data only from those specific devices, while external hard drives serve as physical backups but do not offer the same ease of access over the internet. The mention of software for managing data storage also does not reflect the fundamental concept of cloud storage, which is primarily about storing data online rather than managing it through software.
