TCP/IP

TCP/IP (Transmission Control Protocol / Internet Protocol) is the central protocol suite of the Internet. The name "TCP/IP" is somewhat misleading, as it is usually meant to include other protocols besides TCP and IP, such as ICMP and UDP. These protocols form the heart of the Internet protocol stack, which has, in all, between four and seven layers depending on how you count (doesn't Taco Bell have a burrito like that?). IP distinguishes computers on the Internet by means of IP addresses.
