Cloud computing refers to delivering computing services—such as storage, processing power, and applications—over the internet instead of on local devices. It allows users to access data and applications from anywhere, using any internet-connected device. Cloud services are scalable, cost-effective, and provide automatic backup, security, and collaboration features. Businesses and individuals can avoid investing heavily in physical hardware while enjoying high computing power. Examples include Google Drive, Microsoft Azure, and Amazon Web Services. Cloud computing has transformed data management, enabling remote work, flexible storage, and efficient sharing, making it an essential technology in modern computing.
