Mobile computing allows users to access information and computing resources while mobile. It began in 1981 with the Osborne 1 portable microcomputer. Today's mobile devices like smartphones and tablets use wireless networks to access the internet and cloud-based apps and data from anywhere. They utilize mobile operating systems like Android and iOS and rely on technologies like 4G LTE for high-speed data connectivity on the go. The future of mobile computing may include more powerful devices using nanotechnology, as well as virtual assistants accessible through natural language commands to help users remotely.
