Using (finding) "Eclipse"

[Android Question]

I am trying to run my first app on my computer and it says in the "Running Your App/Android Developer" section:
"To run the app from Eclipse:

Open one of your project's files and click Run from the toolbar.
In the Run as window that appears, select Android Application and click OK.

Eclipse installs the app on your connected device and starts it."

Where do I find Eclipse? Is it (or should it be) on my desktop or on my device?

On your desktop computer, wherever you installed it.

Eclipse is the programming IDE (integrated development environment) that you install on your PC and use to develop your Android applications.
