What is TCP Previous segment / Out-of-order / TCP Dup ACK

edit

Below is the packet capture for a small segment of the application which is getting timed out while the connection is established.

It starts with TCP Previous segment not captured, to TCP Out-of-order and leading to TCP Dup ACK. Below is the format.
