Cloud storage is a service that allows users to save and access their data over the internet instead of on a local computer or hard drive. This means you can store files like documents, photos, and videos on remote servers managed by companies such as Google, Dropbox, or Amazon. Using cloud storage offers several benefits, including easy access from any device with internet connectivity, automatic backups, and the ability to share files with others easily. It also helps free up space on your local devices, making it a convenient option for both personal and business use.
