What is NAK and ACK?
NAK, or “negative acknowledgement,” is a protocol message sent when something’s gone wrong. ACK, or “acknowledgement,” is a protocol message that signifies ”okay, got that, next…” NAK and ACK can be used together, but, more often than not, their use anchors two fundamentally different methods for communicating.
What is NAK frame?
The receiver can send either NAK or ACK depending on the conditions. The NAK frame tells the sender that the data have been received damaged. Since the sliding window is a continuous transmission mechanism, both ACK and NAK must be numbered for the identification of a frame.

If the ACK does not reach the sender before the timeout, the sender re-sends the same packet.

Bisync does not use a single ACK character but has two control sequences for alternate even/odd block acknowledgment.
What is a NACK used for in networking?
NACKs can also be used for detecting errors and packet loss. For example, in reliable multicast, a NACK is sent only when the receiver identifies a lost packet. Application layer protocols.
