According to, “TCP/IP, in full Transmission Control Protocol/Internet Protocol, standard Internet communications protocols that allow digital computers to communicate over long distances.”. TCP/IP was invented/developed in the 1970s by Vint Cerf and Bob Kahn, two DARPA scientists. Some individuals refer to these two inventers as the fathers of the internet. TCP/IP is often referred to a suite because TCP/IP refers to two separate internet protocols.

TCP/IP contains three service layers, excluding the hardware layer. These layers consist of a Network Layer, Transport  Layer, and Application Layer. The Protocol services regarding the Network Layer consist of the Internet Protocol (IP), Internet Control Message Protocol (ICMP), Address Resolution Protocol (ARP), and Reverse Address Resolution Protocol (RARP).  Regarding the Transport Layer, the protocols consist of the, User Datagram Protocol (UDP), and the Transmission Control Protocol (TCP). Finally, the Application layers protocols being utilized consist of the, File Transfer Protocol (FTP), Network File System Protocol (NFSP), Simple Mail Transfer Protocol (SMTP), and finally the Telnet or Virtual Terminal Protocol (NVT).
