The Internet protocol suite is the conceptual model and set of communications protocols used on the Internet and similar computer networks. It is commonly known as TCP/IP because the original protocols in the suite are the Transmission Control Protocol (TCP) and the Internet Protocol (IP).
Packet switching is a philosophy of network communication, not a specific protocol. The protocol used by the Internet is called TCP/IP. The TCP/IP protocol is due to Robert Kahn and Vint Cerf. The IP in TCP/IP stands for Internet protocol and is the protocol used by computers to communicate with each other on the Internet. Computers using the Internet must have IP software. Packets that follow the IP specification are called IP datagrams. These datagrams have two parts: header information and data.
