InRobert E. Kahn joined the DARPA Information Processing Technology Officewhere he worked on both satellite packet networks and ground-based radio packet networks, and recognized the value of being able to communicate across both. By the summer ofKahn and Cerf had worked out a fundamental reformulation, in which the differences between local network protocols were hidden by using a common internetwork protocoland, instead of the network being responsible for reliability, as in the ARPANET, this function was delegated to the hosts. The protocol was implemented as the Transmission Control Program, first published in

Its simplicity and power has led to its becoming the single network protocol of choice in the world today. It connects many universities and government installations using leased telephone lines.

The most accurate name for the set of protocols is the "Internet protocol suite". TCP and IP are two of the protocols in this suite. The Internet is a collection of networks.

Term "Internet" applies to this entire set of networks. This layered representation leads to the term protocol stack, which refers to the stack of layers in the protocol suite. By dividing the communication software into layers, the protocol stack allows for division of labor, ease of implementation and code testing, and the ability to develop alternative layer implementations.

Layers communicate with those above and below via concise interfaces. In this regard, a layer provides a service for the layer directly above it and makes use of services provided by the layer directly below it.

For example, the IP layer provides the ability to transfer data from one host to another without any guarantee to reliable delivery or duplicate suppression.

A few provide "low- level" functions needed for many applications. Others are protocols for doing specific tasks, e. These machines had their own disks, and generally were self contained. An application is a user process cooperating with another process usually on a different host there is also a benefit to application communication within a single host.

Transport Layer The transport layer provides the end-to-end data transfer by delivering data from an application to its remote peer. Multiple applications can be supported simultaneously. The most-used transport layer protocol is the Transmission Control Protocol TCPwhich provides connection-oriented reliable data delivery, duplicate data suppression, congestion control, and flow control.

Another transport layer protocol is the User Datagram Protocol It provides connectionless, unreliable, best-effort service. As a result, applications using UDP as the transport protocol have to provide their own end-to-end integrity, flow control, and congestion control, if desired.

Usually, UDP is used by applications that need a fast transport mechanism and can tolerate the loss of some data. Internet Protocol IP is the most important protocol in this layer. It is a connectionless protocol that does not assume reliability from lower layers.TCP/IP was and is the crown jewel of the US engineering acumen, the technology that changed the civilization as we know it in less then 50 years.

TCP/IP, or the Transmission Control Protocol/Internet Protocol, is a suite of communication protocols used to interconnect network devices on the internet. TCP/IP can also be used as a communications protocol in a private network (an intranet or an extranet).
