Cloud systems refer to a network of remote servers that store, manage, and process data over the internet, rather than on a local computer. This technology allows users to access files and applications from anywhere, using various devices. Popular examples of cloud services include Google Drive, Dropbox, and Amazon Web Services. These systems offer scalability, meaning businesses can easily adjust their resources based on demand. Additionally, cloud systems enhance collaboration, as multiple users can work on the same document simultaneously. Overall, they provide flexibility and efficiency for both individuals and organizations.
