Internet Protocols
Transfer control protocol / Internet protocol (TCP / IP) is the basic protocol that permits communication between Internet sites. It was invented by Vinton Cerf and Bob Kahn under contract from the U.S. Department of Defense to network dissimilar systems. This protocol controls how individual packets of data are formatted, transmitted, and received. This is known as a reliable protocol because delivery of all the packets to a destination is guaranteed. If delivery is interrupted by hardware or software failure, the packets are automatically retransmitted.
