---Assigment 2: TCP/IP - Test Question

1. Why is a 3-way handshake necessary ?

- To make sure the connection from 2 different node
can be established properly and the connection is reliable.

2. Who sends the first FIN - the server or the client ?

- Server send 1st. Its sending the FIN after send out all the data that requested by the
client.

3. Once the connection is established, what is the difference between the operation of the server's TCP layer and the client's TCP layer ?

- If client send the data to the server, it will wait for the server to send the ACK
to the client and same with to other way.This is the different.

4. What happens if a bad guy can guess ISNs ?

- This is very dangerous because the bad guy can steel the such important data such as
credit card balance or others.They will use this information to do the bad things.
