TCP Transmission Control Protocol
UDP User Datagram Protocol
The Defense Advance Research Projects Agency (DARPA) originally developed Transmission Control Protocol/Internet Protocol (TCP/IP) to interconnect various defense department computer networks. The Internet, an international Wide Area Network, uses TCP/IP to connect government and educational institutions across the world. TCP/IP is also in widespread use on commercial and private networks. The TCP/IP suite includes the following protocols

Data Link Layer
ARP/RARP Address Resolution Protocol/Reverse Address
DCAP Data Link Switching Client Access Protocol

Network Layer
DHCP Dynamic Host Configuration Protocol
DVMRP Distance Vector Multicast Routing Protocol
ICMP/ICMPv6 Internet Control Message Protocol
IGMP Internet Group Management Protocol
IP Internet Protocol version 4
IPv6 Internet Protocol version 6
