ADAD meaning in Computing ?

An automatic dialer (also spelled auto dialer, auto-dialer, and autodialer) is an electronic device or software that automatically dials telephone numbers. Once the call has been answered, the autodialer either plays a recorded message or connects the call to a live person.

When an autodialer plays a pre-recorded message, it is often called voice broadcasting, or robocalling. Some voice broadcasting messages ask the person who answers to press a button on their phone keypad, such as in opinion polls in which recipients are asked to press one digit if they support one side of an issue, or another digit if they support the other side. This type of call is often called outbound interactive voice response.

When an autodialer connects an answered call to a live agent, it is often called a predictive dialer or power dialer. A predictive dialer uses real-time analysis to determine the optimal time to dial more numbers, whereas a power dialer simply dials a pre-set number of lines when an agent finishes the previous call.
