There can be an assortment of devices on a network depending on the size. These devices need an effective method of communication between themselves in order to relay 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, 2014). If devices are using different protocols, they cannot understand each other in order to successfully transmit and receive data.
The network for Kudler Fine Foods is that of an Ethernet network. The bus topology used within each store supports fast Ethernet speeds of 100mbps. Each store also has VOIP phones that use Internet Protocol to communicate with the network. The servers and computer stations will communicate with the Ethernet line using the Transmission Control Protocol/Internet Protocol (TCP/IP).
TCP/IP is a network standard that defines how data is sent throughout the network. TCP/IP consists of two different layers. Transmission Control Protocol is the higher layer and manages the assembling of a message or file into smaller packets. After forming the packets, the device will transmit them across the Internet and to be received by a device that is also using the TCP protocol. The device then reassembles the packets into the original message and presents the data to the user. The lower layer is Internet Protocol and handles the...

...ues that are noted. The customers at Kudler Fine Foods will not want to wait until the systems are back up and running for them to purchase their goods. The customers may leave for another store and that is a loss of revenue. Using reliable performance metrics should prevent the network from causing negative impacting occurrences. Backup plans and up to date hardware and software should also be items that provide maximum performance for the network.

Kudler Fine Foods is a store unlike any in the grocery industry. Kudler Fine Foods represents a store that could possibly spark a new era within the grocery world. The owner of Kudler Fine Foods, Kathy Kudler, has watched her dream of owning and operating a grocery store that specializes in fine quality food grow within a short period of time. The success of Kudler Fine Foods can be attributed to the innovative ideas, effective leadership, and organizational structure. The overall mission of Kudler Fine Food's "is to provide our customers the finest in selected foodstuffs, wines, and related needs in an unparallel consumer environment. Our selections coupled with our experienced, helpful and knowledgeable staff, merge to offer each customer a delightful and pleasing shopping outing" (Apollo Group, 2003). Kudler has managed to maintain its mission statement by providing its customers with the best and as a result the company has flourished. "Kathy considers one of her key responsibilities to be that of identification of new gourmet items that can be offered in her stores (Apollo Group, 2003)." Therefore, Kathy is considering plans to contract with local growers of organic produce to yet obtain the best in quality products for her consumers and take her business to the next step. If Kathy makes the decision to contract with local growers then changes could be introduced into the company's overall structural organization. Each aspect of Kudler Fine Food's organizational structure from basic business process to the supply chain and quality control process will be affected by the formation of a contractual relationship with local organic growers.
IP – The Internet Protocol (IP) - is the method or protocol by which data is sent from one computer to another on the Internet. Each computer (known as a host) on the Internet has at least one IP address that uniquely identifies it from all other computers on the Internet.
The OSI network reference model was developed by the International Organization for Standardization (ISO) to facilitate communication between networks by keeping certain standards open rather than proprietary (Serpanos & Wolf, 2011). Each layer is stacked with the physical layer as the lowest and the application layer as the highest and one can think of each layer as containing stacks of protocols that make network communications function (Serpanos & Wolf, 2011). A protocol is a set of rules written in a common language that allows computers to communicate with each other. Each communication network is a node and the corresponding layer on each node communicates with each other.
TCP/IP is a set of rules and regulations which allow for communication to take place. TCP is a protocol a set of rules and regulations that is lets the communication to take place between computers over the internet. TCP is the wrap around a data packet that keeps the data packet intact so it does not break to pieces when it is travelling. On the other hand IP is internet protocol and this protocol makes sure that the data packets know where to go. It makes sure that the data packet knows the route to the receiver of the data packet. IP address is stuck on the data packet it is like a label that has the information of where the data packet has to go and the information of the sender. In order for communication to take place the information has to go through four layers and it all happens in split second.
Before we go too far it should be noted that TCP/IP is really two protocols. The first is the Transmission Control Protocol or TCP. The second protocol is IP which stands for Internet Protocol. These two combined provide the basis for the virtual level of most of the networks we use today. The roots of the protocols reach back into the 1970’s. At that time networks were built by wires connecting one computer to the next directly. This is called direct connect. If you wanted information to get to a computer that yours was not direct connected to you would have to create a bridge on a common machine you are both connected to. This way messages you send in one connection are transferred in the computer to the other connection and sent to the computer you were trying to talk to. This is sometimes called a gateway.
This memorandum will attempt to explain the Open Systems Interconnection Model, known more simply as the OSI Model. The OSI Model has seven levels, and these levels will be discussed in detail. Particular mention will be made to which level TCP/IP functions with the OSI Model.
Next, the writer goes over the second type of network architecture - the TCP/IP reference model, the granddaddy of the wide area computer network. This architecture allows the connection of multiple networks seamlessly. The architecture is flexible and capable of running even if some of the subnet hardware is destroyed or non-functional as long as the source and destination machines are functioning. In a similar fashion to the OSI model, the TCP/IP model has layers as well. In this case, we have four layers: the link
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 layer, the link layer and finally the physical layer. The assignment focuses on the three middle layers and is divided into five parts. Firstly explaining how the TCP and UDP the most vital protocols needed to deliver and communicate.
With the emergence of the Ethernet LAN (Local Area Network) introduced in the early 1970s by Xerox, the telecommunications world has welcomed this newfound gift with open arms. Since communications is such a vital aspect of all businesses these days, proper acquaintance with this marvelous technology can greatly enhance your company's productivity and efficiency. In this paper, we will reflect into the many different characteristics of media that the LANs are based upon and compare/contrast these different medias.
TCP/IP operates at both levels 3 and 4 of the OSI model. The TCP portion of TCP/IP operates at level 3 (Network) as its primary function is to control the flow of data. IP operates at level 4 (Transport) of the OSI model. IP is the protocol responsible for the actual transmission of packet across the network.
In the Open Systems interconnection Model (OSI Model), the network layer lies in the third level and for network communication it provides paths for data routing. It is considered as the backbone of the OSI model because for the purpose for the data transfer between nodes, network layer performs selection and management of the best logical path. Switches, firewalls, bridges and routers are some hardware devices that this layer contains. From the transport layer it responds to requests and issues requests to the data link layer.
