FIN (Final): In the context of network communications, “FIN” refers to a flag that is used in the TCP (Transmission Control Protocol) to indicate that a particular communication session has ended or should be closed. When a FIN flag is sent from one device to another, it means that the device sending the FIN flag has no more data to transmit. This flag is a crucial part of maintaining and closing network connections in an orderly manner.
