When TCP transfers a stream of data, it breaks up the stream into small segments. The TCP Segments chart displays different graphs representing the rate at which TCP segments are transmitted or received in the current Windows system.

Sent

The rate at which TCP segments are transmitted by the current system.

Received

The rate at which TCP segments are received by the current system.

Retransmitted

The rate of transmission of TCP segments that have already been sent, but need to be retransmitted because of packet time-out or some other transmission error.
