Personal and Public communications

Introduction  (Video https://www.youtube.com/watch?v=HPi4FcRKCB8)

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. These may include the health implications of mobile devices, unauthorised access to wireless networks, interception of communications, storage of personal communications for security purposes, and tracking of people.

For clear understanding of this topic, We will first look at different technologies used for Personal and Public communications. Post you notes in OneNote
