The term typically used is the '3-way handshake'.

The purpose of the FIN ACK message in a TCP connection termination process is to acknowledge the receipt of a FIN (finish) message from the other party and signal the completion of the connection termination process.
because the tcp is reliable
A single port can be configured to listen for UDP or TCP inbound connection requests (or both). Telnet uses TCP. So when you telnet to a specific IP:port, telnet will attempt to make a TCP connection. If there is no TCP listener on the port you specify, then the connection request will be refused. It matters not if you have a UDP listener on the port. Telnet will not be able to establish a connection to a UDP port.

69 is the port number of TCP. TCP is the connection reliable protocol which is used to transfer the data in the network.so that dns is not configured properly or tcp/ip settings are not properly.
A built TCP connection refers to an established communication link between two devices using the Transmission Control Protocol (TCP). This connection is formed through a process called the TCP three-way handshake, which involves the exchange of SYN and ACK packets to synchronize and acknowledge the connection. Once established, the connection allows for reliable, ordered, and error-checked data transmission between the devices. This ensures that data sent over the network arrives intact and in the correct sequence.
Connection-oriented
UDP and TCP both are transport layer protocols. UDP is connection less and TCP is connection oriented. UDP is preferred over TCP when large amount data is to be sent like on skype or video conferencing .
The process of a TCP server is to receive TCP connections and handling the data correctly. The letters TCP in TCP server stands for transmission control protocol.
