Basic Network Technology, Structure, and Protocols - Research Paper Example Moreover, the Internet is known as the world’s biggest public WAN and it is too a type of network (Mitchell, 2011) and (FREETECHEXAMS, 2011). There are diverse kinds of networking, for example there are WANs (wide area networks) or LANs (local area networks). However, the dissimilarity among these two depends on their coverage. Additionally, networks can as well be dissimilar in their arrangement and design. In addition, there are various other types as well for instance server/client networks and peer-to-peer networks. Moreover, in some scenarios client/server based networks are inclined to be central by means of the majority processes being maintained by the centralized or key system. On the other hand, the Peer-to-peer networks are composed of computers that facilitate the similar processes as well as are able to transmit data and information to each other (FREETECHEXAMS, 2011) and (Mitchell, 2011). The purpose of networks is to offer data sharing and communication services , for this reason there are some established communication standards those are implemented through protocols. In this scenario, the protocols are similar to the policies and regulations for the processes of the network. In addition, a network can use different protocols depending on the situation, for example TCP/IP, the majority widespread protocol established for the communication on internet as well as in small level networks. Moreover, the networks can be classified as wireless or wired networks. In this scenario, the majority of protocols intended for wired networks are as well facilitated and corroborated by wireless networks. Furthermore, wired networks have been established a long time ago as compared to wireless networks. However, with developments in technology wireless networks are improving and turning out to be more widespread and trustworthy (FREETECHEXAMS, 2011) and (Mitchell, 2011). At the present, networks are used everywhere. From our home telephone lines to TV con nection we are surrounded with communication networks. These networks are able to offer us a lot of facilities and services in form of information and data sharing. On the other hand, majority of the people still do not have any knowledge about the network technology and what are the basic skills behind the scene. In this scenario, there is an awful need of educating people about the network technology and teaching people about this technology based system. For this purpose, TV and internet are the prime means of technology based communication. In addition, through these means we communicate with people as well as transfer data and information. Moreover, we can develop a program based on the presentation which can offer a great deal of support regarding information sharing and data distribution at the network level for guiding the people (FREETECHEXAMS, 2011), (Nash, 2000) and (Mitchell, 2011). However, there are some issues associated with each technology. In the same way, the late st network technologies are also experiencing some of the issues those are hindering in the overall progress and possible evolution of the technology. In this scenario, security in case of network environment is taken as one of the prime factors regarding the network technology and communication. Moreover, these issues become more critical in

LOG503 Managing Logistics Operations (MOD 2) SLP - Essay Example The logistical system of Wal-mart must work flawlessly so as to be able to manage such a big store. Wal-mart has a distribution system that distributes nearly 85 percent of the total wares sold in its own stores (Atchmeyer, 2002). Wal-mart’s major aim is to sell its goods at the lowest price possible (Atchmeyer, 2002; Mohan, 2003). To achieve this, Wal-Mart obtains goods directly from the manufacturers and sells them directly to its retail customers bypassing all intermediaries (Mohan, 2003). Thus Wal-mart has its own distribution centers strategically located at different locations all over the US. The strategy employed here is that one distribution store can serve 150-200 stores (Atchmeyer, 2002). This has made sure that the stores no matter how far they are are within one day’s driving distance (Atchmeyer, 2002). The distribution centres operate 24 hours a day because the conveyer belts are laser-guided (Atchmeyer, 2002). An advanced opportunistic cross-docking procedure is in use; as the goods are picked directly from the manufacturer’s premises and directly taken to the retail consumers. This ensures that the systems are very efficient as well as they do not need to store the material (Atchmeyer, 2002). It is basically from the stores directly to the shelves. The company owns a fleet of over 12,000 trailers 3,000 trucks (Mohan, 2003). In contrast to its competitors who subcontract the trucking services (Magretta, 2002). Additionally, the company is quite meticulous in hiring its drivers. For a driver to qualify to work for Wal-Mart, they got to have a track record of over 300,000 accident free miles without any major traffic violations (Mohan, 2003). Wal-Mart has developed a number of methods to individually deal with each of its stores inventory (Magretta, 2002). The solutions are tailor made for each individual store in order to cover the logistical challenges posed. These measures
