Is also known as pervasive computing.
Refers to use of computers in everyday life.
New Type of relationship between peoplesand computer
Includes PDAs, smart phones and otherdevices.
Will become a larger part of our social lives.

DEFINITIONS:
The method of enhancing computinguse by making many devices (services)available throughout the physical
environment, but making themeffectively invisible to the user.
many embedded, wearable, handheld
devices communicate transparently toprovide different services to the users

Major focus on Users & there tasks.
Lack of applications in existing systems.
Architecture needs to :
be simple
integrate support for mobilecomputations and persistent
storage.
be easy to encapsulate.

FOUR BASIC MEANS FOR OBTAINING
HIGH DEPENDABILITY
fault prevention:
preventing the occurrence of faults.
fault tolerance :delivery of service in presence of faults.
fault removal:
verification & validation.
fault forecasting:
system evaluation.

UBI-BAT
This location tracking system has three parts:
Bats: - small ultrasonic transmitters worn by users.Receivers:-ultrasonic signal detectors embedded
in ceiling.CentralController:- coordinates the bats and
receiver chains.
