A PC is downloading a large file from a server. The TCP window is 5000 bytes. The server is sending the file using 1000-byte segments. How many segments will the server send before it requires an acknowledgment from the PC?
5 segments
10 segments
1 segment
15 segments
Which factor determines TCP window size?

What happens if part of an FTP message is not delivered to the destination?
Message is lost
The whole Message is re-sent after a period of time
The FTP source host sends a query to the destination host
The part of the FTP message that was lost is re-sent
