The ACK (acknowledgment) frame is an important part of the TCP (Transmission Control Protocol) protocol. It is used to confirm that a data packet has been received by the intended recipient, which helps to ensure reliable transmission of data.
When a sender transmits a packet to a receiver, it waits for an ACK frame before sending the next packet. If the sender does not receive an ACK frame within a specified time, it assumes that the packet was lost or corrupted, and resends it. This helps to reduce the risk of data loss or corruption in the transmission process.
In summary, the role of the ACK frame in the TCP protocol is to confirm the successful delivery of a data packet and ensure reliable transmission of data.
