SLIP is a TCP/IP protocol used for communication between two machines that are previously configured for communication with each other. For example, your Internet server provider may provide you with a SLIP connection so that the provider's server can respond to your requests, pass them on to the Internet, and forward your requested Internet responses back to you. A better service is provided by the Point-to-Point Protocol (PPP). Point-to-Point Protocol is a protocol for communication between two

TCP/IP is a network model which enables the communication across the Internet. The most fundamental protocol on which the Internet is built. This is made up of the 2 common networking protocols, TCP, for Transmission Control Protocol, and IP, for Internet Protocol. TCP maintains and handles packet flow linking the systems and IP protocol has the ability to handle the routing of packets. However The TCP/IP stack consists of 5 layers first being application layer, the transport layer, then the network

provides more fast communication, better connectivity and transparency and there is no need for separate gateways in order to connect the devices. As an example Common Industrial Protocol (CIP) has implementations based upon Ethernet and the IP protocol suite (EtherNet/IP), DeviceNet, and ControlNet (among others). Most of the controllers can transfer data from one network type to another, leveraging existing installations, by utilizing the advantage of Ethernet. The fieldbus data structure is applied to

1.4 – Reference Models Section 1.4 is basically the author telling us about two important network architectures, the OSI reference model and the TCP/IP reference model. The OSI (Open Systems Interconnection) deals with connecting opens systems, which are systems that talk with other systems. This model has seven layers: the physical layer, the data link layer, the network layer, the transport layer, the session layer, the presentation layer, and the application layer. From this information, we discover

for the language computers use to transmit information are called protocols. As with the many different languages people around the world use to communicate, there are many different protocols. Some of these protocols include IPX, SPX, NetBEUI, TCP, and IP. Without protocols, communication between computers on a network would not be possible. Each protocol has it’s own set of responsibilities and characteristics. Some protocols are faster, and others are more reliable. Compatibility Protocol

many computer network systems such as private, public, business or government network interconnected globally to transmit and exchange data through various types of media such as guided media, wireless and fibre-optic technologies. The Internet uses TCP/IP protocol suites in their global communication system including hardware and infrastructure. The Internet provides many communication services among their users in information dissemination. The history of communication services were first developed

TCP/IP Name Affiliation Date TCP/IP Introduction TCP stands for Transmission control protocol while IP stands for Internet protocol. They are merged together to form the Internet protocol suit which is a model for networking which consists of communication protocols which are used for internet and other similar networks. This protocol suite was designed and developed by the Department of Defense (DoD). It was developed in order to connect different networks which were designed by different

Abstract : Internet Protocol version 6(Pv6) is the advanced version of the IPv4 protocol and both of these protocols are part of TCP/IP suite.TCP/IP is the only protocol for transmission of data over the internet As the internet is not secure place for transmission of secure and confidential information (packets) So to protect this information over the non secure channels(internet ) the IPSec was introduced .IPSec is the worldly know standard for the secure transmission over the internet . IPSec

TCP/IP Overview When designing networked applications one key protocol stands out as the foundation for making it possible. That protocol is TCP/IP. There are many protocols out there that allow two applications to communicate. What makes TCP/IP a nice protocol is that it allows applications on two physically separate computers to talk. What makes TCP/IP great is that it can do with two computers across a room or across the world. In this paper I will show you how TCP/IP allows a wide array of computer

of computers. The topic of this paper is TCP/IP and their designers, Vinton Cerf and Robert Kahn. TCP/IP stands for Transmission Control Protocol/Internet Protocol, which is the protocol of the Internet. In a private network, TCP/IP can be used as a communications protocol; the TCP/IP can either be an intranet or extranet. A computer is provided with a copy of the TCP/IP program when it is set up with direct access to the Internet. (“What Is TCP/IP”) TCP/IP is a two-layer program. The higher layer

screen or that email to Aunt Lucy get there so fast and reliably? Well thanks to something called TCP/IP, and the US government who funded the research to develop it, we can communicate across the world in seconds. This amazing feat took years of research and the work of some very smart people in the Department of Defense whose job was to develop reliable and secure communications for the US Military. TCP stands for Transmission Control Protocol which basically is a set of rules or procedures that have

TCP/IP The OSI reference model or Open System Interconnection is the most common model used in today’s networks. The OSI model divides the required network processes into seven different layers allowing for effective communication. Layer 7 or the Application function provides network services to application processes, interacts and supports the networks needs of various software’s, and provides protocols. Layer 6 or Presentation function provides proper communication from one host to another. With-in

detection(CD). This layer prevents hosts from transmitting simultaneously on the channel resulting in damaged frames. So it doesn't allow damaged packets to propagate up the stack and cause unnecessary retransmissions at the LLC layer which can interfere with TCP retransmissions. We know that collision detection is harder in wireless networks due to the “hidden-terminal” problem. But we can still use “collision avoidance” mechanisms to ensure that no two hosts transmit simultaneously. Collision avoidance mechanisms

critical. TCP/IP, the network protocol, was invented by the Department of Defense due to its complex network requirements. TCP/IP provided a common protocol suite that could be specified for all networks, would operate with equipment from various vendors, was easy to configure, high performing, and reliable. TCP/IP is a protocol suite, or group of protocols, which allows communication over the Internet of in private networks ranging from home offices to enterprise networks. TCP/IP is constructed

UNDERSTANDING THE OSI MODEL AND THE RELATIONSHIP WITH TCP/IP The Open Systems Interconnection (OSI) model is a reference tool for understanding data communications between any two networked systems. It divides the communications processes into seven layers. Each layer both performs specific functions to support the layers above it and offers services to the layers below it. The three lowest layers focus on passing traffic through the network to an end system. The top four layers come into

Mesh, Bus, Ring and Star Topologies Mesh A mesh topology typically refers to a Wide Area Network where there are multiple paths connecting multiple sites. A router is used to search multiple paths and determine the best path for the data. Routes are determined by least cost, time of day and performance. A three or four site mesh network is relatively easy to create, whereas it is impractical to set up a mesh network of 100 sites or nodes. Mesh networks are used in Wide Area Networks (WANs) where

properly, you need a basic understanding of TCP/IP (Hunt & Thompson, 1998). Internet Protocol version 4 is the current standard “IP” protocol used with Transmission Control Protocol/Internet Protocol (TCP/IP), which is the protocol for Internet addressing. Like the Open System Interconnection (OSI) model, TCP/IP has its own model. The TCP/IP network model represents reality in the world, whereas the OSI model represents an ideal. The TCP/IP network model has four basic layers. The first layer, Network

the information to the correct destination. The communication protocols are a set of standards that tell different hardware and software how to transfer data elements between them. When working with the OSI model, the protocols will govern communication between entities on the same reference model layer. Network protocols include mechanisms for devices to identify and make connections with each other, as well as formatting rules that specify how data is packaged into messages sent and received (Mitchell

TCP, or transmission control protocol, is one of the most fundamental aspects of guaranteed information transfer on the Internet. As the fourth layer in the OSI model, the TCP protocol ensures that all data sent from one IP address is, in fact, received by another IP address. If a packet did not make it the recipient IP, TCP would call for the packet to be sent again, until confirmation of reception. It is due to these reasons that TCP grants the user the capability of providing stream based transfer
