Explanation

ACK (Acknowledgment) Flag: The ACK flag in the TCP header acknowledges the successful receipt of data by confirming the receipt of a packet or segment. It validates that the receiver has received a particular sequence number and acknowledges the next expected sequence number. It does not close sessions but rather acknowledges data within an ongoing session. RST (Reset) Flag: The RST flag, on the other hand, is used in TCP to immediately terminate a connection. When a device receives a packet with the RST flag set, it indicates an abnormal condition or an attempt to reset or abort an ongoing connection. The RST flag is used to forcefully close a session and reset the connection.
