Sandbox:

This is copy of your organization in a separate environment which can be used for testing, training, development etc.. 

These are completely isolated from your production or live organization that is the operations you perform in your sandboxes don’t affect your Salesforce production organization. 

Please note, Sandboxes are locked when all the licenses for a type of sandbox expire. Salesforce deletes sandboxes that have been locked for 60 days.
