readback

Noun

1. The act of reading data back from a location where it has been stored.
   • If buffer readbacks are used, it is therefore important to try to reduce both the number of readbacks issued and the amount of data read back. - 2005, Christer Ericson, Real-time collision detection, page 415:
2. The repetition of a message one has received, in order to acknowledge it and to demonstrate accurate comprehension (especially of commands).
3. The reading aloud by a transcriptionist, court reporter, or stenographer of draft correspondence or of testimony previously taken down in dictation, usually at the request of the presiding judge or parties involved in a deposition (courtroom contexts) or of the manager dictating the correspondence (business contexts).
   • OK, now let's do a readback before you send this off.
   • The judge ordered a readback of a portion of the testimony.
