Back Ground

• The name ubiquitous computing was coined by Mark
  Weiser(Father of Ubiquitous Computing).
• A technology trying to embed the PCs into
  everyday objects to make the PCs invisible.
• UbiquitousBeing or seeming to be everywhere at
  the same time(omnipresent).
• Later this was renamed as pervasive computing.
• PervasiveCapability to spread throughought.
• Meaning Spreading the computation power into
  everything around us.

Characteristics of Pervasive computing

• Use of Smart Spaces.
• Smart space A space filled with
  intelligent computing
  infrastructure
• Invisibility Minimal User distraction.
• Localized Scalability Density of Interactions.
• Masking Uneven conditioning Dealing with
  different environments.

Conclusion

• A futuristic technology which can change the feel
  and look of Distributed systems in the near
  future.
• Lots of supporting technologies need to be
  developed.
