TCP/IP stands for Transmission Control Protocol/Internet Protocol and is a suite of communication protocols used to interconnect network devices on the internet.
TCP/IP is also used as a communications protocol in a private computer network (an intranet or extranet).
The IP suite follows a client/server model, in which multiple client programs share the services of a common server program.
Protocols in the suite define end-to-end data handling methods for everything from packetizing, addressing and routing to receiving.
The four core protocols used in the TCP/IP suite are: The Internet Protocol (IP) The Internet Control Message Protocol (ICMP) The Internet Group Management Protocol (IGMP)
