Developments in technology have allowed an increasing number of mobile devices to be developed that enable people to communicate anytime, anyplace, anywhere. There is a wealth of information available to society that can be accessed on demand and has changed the way in which people behave.
It is important that the ITGS student is able to discuss the social impacts and ethical issues related to these technologies.
