SYN Flood. A method that the user of a hostile client program can use to conduct a denial-of-service (DOS) 
attack on a computer ser ver. The hostile client repeatedly sends SYN (synchronization) packets to ever y 
port on the ser ver, using fake IP addresses.
T
TCP/IP (Transmission Control Protocol/Internet Protocol). A method of packet-switched data 
transmission used on the Internet. The protocol specifies the manner in which a signal is divided into par ts,
