Web Science/Part1: Foundations of the web/Transmission Control Protocol/Three way handshake/quiz

{Which flags are set in which phase of the handshake messages +- 1st Message ++ 2nd Message -+ 3rd Message
 * type="[]"}
 * SYN|ACK

{What is the difference between a TCP client and a TCP server?} - only if the client asks for data the server can respond with data + only clients can start the process of a three way handshake - only servers can start the process of a three way handshake + once the connection is established both the client and server can send data at any time. - there is not difference between client and server

{Once the three way handshake was used to establish a connection. What will happen if a packet from host A is not acknowledged?} - the connection will be closed by A + the packet will be send over and over again by A - A initiates a trace root so that it can decide if there is still a physical connection with the recipient. - A will send the packet again with an increased priority
