Callback

Callback


A callback may refer to any of the following:

  • A security feature that verifies the dial-in user is whom they say they are by calling the person back. After the callback and the username, password, and any other information are verified, they are granted access.

  • A callback is also another name for a returned phone call.

  • In computer programming, a callback is a function, procedure, or method, which is passed as an argument to another function. The callback is then called later when the appropriate conditions are met. Callbacks are often lambda functions, and are a characteristic component of many programming paradigms including event-based programming.
