What is confirmation code (ACK)?
A confirmation code (ACK) is a type of unique signal sent by a computer to show that data has been successfully transmitted. The confirmation code is an ASCII character that is intended to serve as a signal between the sender and receiver.
A verification code is also known as a verification character.
The verification code illustrates the way different senders and recipients handle data blocks. There is a specific protocol or known size for a block of data that the sender data must conform to. When the recipient receives the correct block of data, they send the confirmation code back to the sender, and the sender sends another block. This iterative process helps ensure that large amounts of data are effectively delivered from a sender to a receiver.
