Why Use IT to Help Communicate Information?
Examples of personal communication: You may want to tell your friends about a party that you are having, or you may want to let others know how about the impact of climate change.
Examples of business communication: In business, you may want to tell the world about a new product that your company has just created (this is called marketing), or you have information that you need to pass on to all of the employees in the business.
In all of these examples, IT can be used to help pass on the message.
Producing and Editing Pictures
- Crop (cut off bits that you don't want)
- Distort (e.g. bend, twist, stretch, etc.)
- Alter colour (e.g. brighten, make black & white, etc.)
- Add effects (e.g. shadows, glow, texture)
- Add graphics (e.g. lines, circles, borders, etc.)
- Add text
Document layout is produced using 'frames' - areas of the page that can contain text or images.
- Hyperlinks (to jump to other content)
However in some ways websites are not as good as printed documents for reaching people. Fore example, to view websites:
- You need a computer (expensive)
- You need an Internet connection (not always available, and it can be expensive)
- You need some training to know how to use a computer (you don't need training to use paper!)
To produce a musical score (sheets of written notes), you no longer need to write every note down by hand. You can use a WYSIWYG editor to write the music on the computer, edit it, print copies, etc.
With the rise of the Internet, and especially with the recent 'Web 2.0' websites, such as wikis, blogs and social networking sites, communication has now become very interactive.
By 'interactive' we mean that people can respond the information that they are given, add comments, alter / improve it, rate it, etc.
