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

1 Which flags are set in which phase of the handshake messages

SYN	ACK
		1st Message
		2nd Message
		3rd Message

2 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

3 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
