Techopedia Explains Acknowledgement Code

The acknowledgement code illustrates the ways that various
senders and receivers handle blocks of data. There is a certain protocol or
familiar size for a data block, to which the sender data must conform. When the
recipient gets the right data block, it sends the acknowledgement code back
to the sender, and then the sender sends another block. This iterative process
helps ensure that large amounts of data get delivered from a sender to a receiver
effectively.
