Pervasive Computing A Definition

• Pervasive Computing is the study of a computing
  technology that pervades the users environment.
• It does so by
• Making use of multiple independent information
  devices (fixed or mobile, homogeneous or
  heterogeneous)
• Interconnecting these devices seamlessly through
  wireless or wired computer communication networks
  
• Providing a class of computing / sensory /
  communication services to a class of users,
  preferably transparently and can provide
  personalized services while ensuring a fair
  degree of privacy / non-intrusiveness.
