In previous article you found out what you can do with Ubuntu's Main Menu. Today, in this last Ubuntu's introductory article, you will see purpose of Indicators. Indicators are placed at  a right upper corner as shown in figure 1.

If you type word indicator in a dictionary you might end up with a lot of explanations in various contexts.  Despite that, in almost every explanation you could extrude key words: pointer, signal, orientation.

Indicators in Ubuntu are signaling you:

1. That there are new drivers available to install.

2. That you  received an e-mail or friend wants to chat with you...

This is not all considering Indicators. You have just seen the surface. Indicators are not here just so you could see the state of some part of your system. You can also configure and adjust: e-mail, sound, network connectivity etc...

Since this is just an introductory article there won't be any details considering configuration nor adjustment of previously shown indicators.

This was the last Ubuntu's introductory article. I hope you find it useful.
