Network -A network can be defined as a group of computers and other devices. will introduce you to four common network protocols found in networking network when two systems use two totally different protocols—everyone is talking .

    Contributor s : Alissa Irei and David Udiminue Share this item with your network: A network protocol is a set of established rules that dictates how to format, transmit and receive data so computer network devices -- from servers and routers to endpoints -- can communicate regardless of the differences in their underlying infrastructures, designs or standards. To successfully send and receive information, devices on both sides of a communication exchange must accept and follow protocol conventions. Support for network protocols can be built into software, hardware or both. Standardized network protocols provide a common language for network devices. Without them, computers wouldn't know how to engage with each other. As a result, except for specialty networks built around a specific architecture, few networks would be able to function, and the internet as we know it wouldn't exist. Virtually all network end users rely on network protocols for connectivity. How protocols work Network protocols break larger processes into discrete, narrowly defined functions and tasks across every level of the network. In the standard model known as Open Systems Interconnection OSI , one or more network protocols govern activities at each layer in the telecommunication exchange. A set of cooperating network protocols is called a protocol suite. These include: Transmission Control Protocol TCP , which uses a set of rules to exchange messages with other internet points at the information packet level; Internet Protocol IP , which uses a set of rules to send and receive messages at the internet address level; and additional network protocols that include the Hypertext Transfer Protocol HTTP and File Transfer Protocol FTP , each of which has defined sets of rules to exchange and display information. Network protocols are often set forth in an industry standard -- developed, defined and published by groups such as the International Telecommunication Union , the Institute of Electrical and Electronics Engineers , the Internet Engineering Task Force , the International Organization for Standardization and the World Wide Web Consortium.

    The WAN protocol suite is for the lowest three layers and defines communication over various wide-area media, such as fiber optic and copper cables. Network communication has slowly evolved.

    Today's new technologies are based on the accumulation over years of technologies, which may be either still existing or obsolete. Because of this, the protocols which define the network communication are highly inter-related. Many protocols rely on others for operation. For example, many routing protocols use other network protocols to exchange information between routers.

    In addition to standards for individual protocols in transmission, there are now also interface standards for different layers to talk to the ones above or below usually operating system specific.

    The protocols for data communication cover all areas as defined in the OSI model.

    However, the OSI model is only loosely defined. A protocol may perform the functions of one or more of the OSI layers, which introduces complexity to understanding protocols relevant to the OSI 7 layer model. In real-world protocols, there is some argument as to where the distinctions between layers are drawn; there is no one black and white answer. To develop a complete technology that is useful for the industry, very often a group of protocols is required in the same layer or across many different layers.

    Different protocols often describe different aspects of a single communication; taken together, these form a protocol suite. Protocols can be implemented either in hardware or software or a mixture of both.

    Typically, the lower layers are implemented in hardware, with the higher layers being implemented in software. Protocols could be grouped into suites or families, or stacks by their technical functions, or origin of the protocol introduction, or both. Detailed rules and procedures of a protocol or protocol group are often defined by a lengthy document.

    A wide variety of communication protocols exists.

    These protocols were defined by many different standard organizations throughout the world and by technology vendors over years of technology evolution and development. The IP, the Internet Protocol, is responsible for exchanging information between routers so that the routers can select the proper path for network traffic, while TCP is responsible for ensuring the data packets are transmitted across the network reliably and error free.

    The LAN protocols suite is for the physical and data link layers of communications over various LAN media such as Ethernet wires and wireless radio waves. The WAN protocol suite is for the lowest three layers and defines communication over various wide-area media, such as fiber optic and copper cables. Network communication has slowly evolved. Today's new technologies are based on the accumulation over years of technologies, which may be either still existing or obsolete.

    Because of this, the protocols which define the network communication are highly inter-related.
