Which of the following is not an example of cloud storage?

Concept: Cloud storage is a service model in which data is stored on remote servers owned and maintained by a third-party provider, then accessed and synchronized over the internet from any connected device, instead of being saved only on a local physical drive.

Application: Checking each of the four names against this definition, three of them are third-party services built exactly on this remote-server-plus-internet-access model, while the fourth does not correspond to any established file-hosting brand offering such a service.

• Dropbox, launched by Dropbox Inc. in 2007, is a widely used remote file-storage and synchronization platform.

• OneDrive is Microsoft's remote file-storage service, bundled with Windows and Microsoft 365.

• Google Drive, launched by Google in 2012, is a remote file-storage and synchronization platform integrated with Google Workspace.

• "LX Drive" is not tied to any recognized technology company or file-hosting product in the industry.

Conclusion: Since Dropbox, OneDrive, and Google Drive are established remote/cloud storage platforms while "LX Drive" is not, LX Drive is the one that is not an example of cloud storage.
