Cloud applications are software programs that run on remote servers instead of being installed on a local computer. Users access these applications over the internet, allowing for flexibility and convenience. Examples include Google Drive for file storage and Salesforce for customer relationship management. These applications often offer real-time collaboration, automatic updates, and scalability, making them ideal for businesses and individuals alike. By utilizing cloud technology, users can access their data and applications from any device with an internet connection, enhancing productivity and efficiency.
