Explanation:

: This is the correct order of a TCP session, the user send a “SYN” packet to the server (ask the
server for a connection), the server sends to the user a “SYN/ACK” packet (telling the client that
he is going to open a port for the connection and giving his ACK), then the user send the server an
ACK (to complete the negotiation of the session), once this 3 way handshake process is done, the
two sides can begin the exchange of data.
