### Discussion

Perhaps you are a ‘consumer’ of media, and you like to watch television, listen to the radio, listen to music and look at pictures online. Do you also look at photographs and videos shared by my friends and colleagues on social networking sites?

Possibly you are also a media ‘creator’, and take photographs on your camera and share them electronically later. On short visits to places and events, many people use their smartphone to record some of the things they see and hear and post directly to social networking sites.

In using and creating digital media, we are often representing part of the real world in a digital form that can be stored, transmitted or manipulated using information and communication technology.
