Connection-oriented means that, before any data can be transmitted, a reliable connection must be obtained and acknowledged. TCP level data transmissions, connection establishment, and connection termination maintain specific control parameters that govern the entire process. Thanks Comment

TCP (Transmission Control Protocol) is a connection-oriented protocol for transferring data reliably in either direction between a pair of users.
The events occurred in the three-way handshake:
Scenario between the client and the server:
Process happening in Client side:
Connection Established: Transmit: When the process is done, the application using TCP signals that the connection is no longer needed.
FIN-WAIT 1: The client, having sent a FIN, is waiting for acknowledgment and for the server to send its own FIN.
FIN-WAIT -1: The client receives the ACK for its FIN.
FIN-WAIT -2: The client is waiting for the server's FIN.
TIME-WAIT: The client waits for a period of time to double the maximum segment life (MSL) time, to ensure the ACK it sent was received.
CLOSED: Now, the connection is closed.
Process happening in Server side:
ESTABLISHED: At this stage, the server is still in normal operating mode.
CLOSE WAIT: The server waits for the application process on its end to signal that it is ready to close.
LAST ACK: The server is waiting for an ACK for the FIN that to be sent.
CLOSED: The connection is closed on the server's end.
