Ubiquitous computing

2. WHAT IS UBIQUITOUS COMPUTING?
 It is also called pervasive computing.
 Ubiquitous computing (ubicomp) is a concept
in software engineering and computer science
where computing is made to appear anytime
and everywhere. Ubiquitous computing can
occur using any device, in any location, and in
any format.

3.  The word pervasive and ubiquitous means
“Existing Everywhere” .
 It supports one user to many computers.

4. EXAMPLE OF UBIQUITOUS COMPUTING :

5.  An other example of practical application or
pervasive computing is the replacement of old
electric meter with smart meter.

6. HISTORY OF UBIQUITOUS COMPUTING
 The father of ubiquitous computing is ‘MARK
WEISER’ who was also the chief scientist at
Xerox PARC(Palo Alto Research Center) in the
United State and invented the term ‘Ubiquitous
Computing’.
 Researcher in the C.S. lab at research center
first articulated the idea of ubiquitous computing
in 1988 & has called UC “....highest ideal is to
make computer so imbedded , so fitting, so

7. THREE GENERATION OF COMPUTING :
 The first era of computing is known as
mainframe era – many people to one computer,
this computer was the central system from which
entire offices, and sometimes, companies called their
computing infrastructure.
 The second era of computing is known as the PC era-
one computer to one person.
 The third era of computing is known as the
UBIQUITOUS COMPUTING - one person using many
computers.

9. ADVANTAGE :
Manage informaion quickly, efficiently.
Remove complexity of new technology.
Invisible.
Socialization.
Decision Making.
Information processing.
Enhancing Experience.

10. APPLICATIONS :
Information access.
Text retrieval.
Multimedia document retrieval.
Automatic indexing.
Networking.
Electronic books.
Speech Recognition.
Wireless protocols.
User sensitive device.

11. WHY IS UBIQUITOUS COMPUTING
IMPORTANT ?
 Communicate in different ways
 Be more active
 Have more control
 Social & Personal

12. KEY ELEMENTS OF UBIQUITOUS
COMPUTING :
 Ubiquitous access
 Ubiquitous middleware
 Ubiquitous networking
 Ubiquitous sensing

18. USES OF PERVASIVE COMPUTING :
BUSINESS USES
Healthcare Military Micropayment

20. Personal Uses
Personal
Information
Flight
Schedule
Location

23.  Pervasive computing not entirely secure.
 Frequent line connection that are broken.
 Slow connection.
 Very expensive operating cost.
Disadvantage :

24. CONCLUSION
 removal of wires in the network computing
available to everyone, everywhere.
 information can be accessed when & where it
is needed.
 but still privacy & security major drawback of
the pervasive computing.
 computational power will be available every
where through mobile and devices…..
