What is iCloud?
iCloud is Apple's cloud service that provides storage and synchronization for personal data across devices. It is used by individuals with Apple devices to keep their photos, files, notes, and other information accessible and up-to-date. The service helps ensure important data is backed up and available from various locations. Users store photos and videos in iCloud Photos, access documents through iCloud Drive, and manage emails with iCloud Mail. It also syncs notes, contacts, and calendar events. The Find My feature helps locate lost Apple devices. Data is accessible not only on Apple devices but also through a web interface.
