It is essential to find transmission errors when they are received. The data could become useless or, worse, just wrong with just one flipped bit in a crucial spot. There are ways to guarantee that every message is delivered intact even when there is no redundancy in the transmission method. ACK packets, which are sent by the recipient after each data packet is sent, serve as the first line of defense. After transmitting, a device waits for a corresponding ACK from the recipient; if no ACK is returned, the sending unit assumes the data wasn't received properly and immediately sends it again. A message with a variable length is turned into a fixed-length, one-of-a-kind code by a hashing function. When hashing the data it recorded, the receiver employs the same process.
