IT: Information

# Conclusion

The theme of this course has been the impact that information and communication technologies have had on the news industry. I introduced this theme with a short historical overview of technology in the news industry followed by a look at how technology is used for newsgathering.

We have been looking in some detail at aspects of the underlying technologies used in newsgathering, including the basic components of digital camcorders and the methods of signal transmission over wires. We have used some mathematical methods, with a particular emphasis on equations that can be represented with a formula triangle. We have also explored some basic ideas about electricity in the context of the batteries that are needed to supply the power for portable IT equipment.

Finally we have considered the issue of trust in information, and the way in which recent developments in IT have required us to think again about what enables us to trust information.
