What is a volatile system? List the main types of changes that occur in a ubiquitous system
What will be an ideal response?
A volatile system is one in which certain types of change are the rule rather than the exception. In a ubiquitous
system, the set of devices and software components can change regularly, as well as the set of users. Devices
may fail, e.g. due to battery failure. Users may bring devices in and take them out again. Changes in the set of
associations may result. The state of connectivity between devices may also change, due to the way ubiquitous
systems are integrated with physical objects that may affect wireless transmission.
