What is Pervasive Computing?

Pervasive computing is a model of computing in which computer functions are integrated into everyday life, often in an invisible way. The model requires both small, inexpensive computers and wired and wireless ("dumb") devices connected to larger computers. A household controlled by ubiquitous computing might have remote-controlled lighting, automated sprinklers, a home entertainment center, devices to monitor the health of occupants, and a refrigerator that warns occupants about stale or spoiled food products
