Cloud storage refers to the online service that allows users to store, manage, and access data remotely via the internet. Instead of saving files on a local hard drive, cloud storage utilizes a network of remote servers to maintain data, ensuring accessibility from various devices. Benefits include enhanced collaboration, automated backups, and scalable storage options, depending on user needs. Service providers, such as Google Drive, Dropbox, and Amazon S3, offer different storage plans to accommodate individual and organizational requirements. Overall, cloud storage promotes efficiency and flexibility in data management.
