Hai Eneryone,
Good Evening,
Pervasive computing (also called ubiquitous computing) is the growing trend towards embedding microprocessors in everyday objects so they can communicate information. The words pervasive and ubiquitous mean "existing everywhere." Pervasive computing devices are completely connected and constantly available.
Pervasive computing relies on the convergence of wireless technologies, advanced electronics and the Internet. The goal of researchers working in pervasive computing is to create smart products that communicate unobtrusively. The products are connected to the Internet and the data they generate is easily available.
Privacy advocates are concerned about the "big brother is watching you" aspects of pervasive computing, but from a practical standpoint, most researchers feel it will improve efficiency. In a 1996 speech, Rick Belluzo, who was then executive VP and general manager of Hewlett-Packard, compared pervasive computing to electricity. He described it as being "the stage when we take computing for granted. We only notice its absence, rather than its presence."
