Pervasive computing is based on that technology is moving beyond the personal computer to everyday devices with embedded technology and connectivity as computing devices become progressively smaller and more powerful. Pervasive computing goes beyond the realm of personal computers: it is the idea that almost any device, from clothing to tools to appliances to cars to homes to the human body to your coffee mug, can be imbedded with chips to connect the device to an infinite network of other devices.
Mobile computing enables continuous Internet access of computing devices (laptops, smart phones sensors etc.) via a multitude of access networks with maintained service availability. Mobility is enabled by devices connecting to access technologies that scales for a service. Further, software may be moving to be executed on the most efficient device present, adapting to its environment.
