Cloud storage refers to the practice of storing data on remote servers accessible through the internet rather than on local devices. Users can save, manage, and retrieve files from virtually anywhere, facilitated by cloud service providers. This model offers benefits such as scalability, as users can adjust storage capacity according to their needs; cost-effectiveness, as it often eliminates the need for physical storage infrastructure; and enhanced security features, with data redundancy and backup options provided by the service. Cloud storage is commonly used for personal files, business data, and collaborative projects.
