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. One of the main benefits of cloud storage is that it enables easy access to your files from any device with an internet connection. Additionally, it often includes features like automatic backups and file sharing, making it convenient for both personal and professional use.
