Sandbox

A network or series of networks that are not connected to other networks.

A testing location where you can test the functionality of your application without affecting production, incurring charges, or purchasing products.

Comprises a number of cooperating system components, ranging from security managers that execute as part of the application, to security measures designed into the Java virtual machine and the language itself. The sandbox ensures that an untrusted, and possibly malicious, application cannot gain access to system resources.
