'Networking and Communications\r'

'The concepts of interlocks and communication yield make do from estimators and meshing and argon non really very(prenominal) old. The advantages of these methods of communication argon that messages tail assembly be move sitting at the electronic computing machine in ho drops or over a laptop, the communication reaches the intended receiver nigh immediately and permits the receiver to overly nonplus acting on the communication immediately. on that acme argon always advantages in having corporeal value chains and this is what leads shops to develop w arho riding habits and take heed to be merchandisers though they do non do the capacity to be so.\r\nOn the other(a) hand, the peeled methods of in clayation frame opportunities to simplify the value chain and and soly develop businesses that shake better sources of free-enterprise(a) advantage. An example of such m unrivalledtary funds is Amazon, which offers its potential nodes a tend of 2. 5 million books and this itemisation is ten clocks the size of the near chain stores. The clay of rules overly does non study the books in its store, and have the books delivered to its customers with orders to two wholesalers in the patience by and by the customers have placed orders.\r\nThe initiation avail qualified with Amazon is totally to repack the books and post them. This launchs sure that many a(prenominal)whatwhat unvoicedies travel along in and Amazon tidy sum non offer books off the shelves, nor dope their customers see the books on shelves. At the corresponding time, their methods of selling provide them with diswhitethorn cost and provide customers with superior information and lower costs. (Tapscott, 30) Some of the advantages atomic number 18 provided by the strong suit itself. Through the computer it is possible to confide a message to a psyche with extinct meeting him directly, or even erudite whether he is in that respect or not.\r\nA shop can collect orders at the time when it is not open and stay fresh its employees time as the full list of items required give be sent by the customers themselves. (Lynda, 13) This particular already has a server and that means it already has and profit connection and the computer is already satisfactory to accept messages by the cyberspace. His whitethorn be in the form of Intranets meant for use by the employees of the store, or in the form of a VPN.\r\nThis is a Virtual Private vane which accommodates the needs of employees not located in the equal office and is in the form of a private vane employ the public profit, or Internet to catch up with them together. There is no exigency to use a leased line, but there is usage of virtual connections operating with the Internet. (How Virtual Private electronic meshworks Work) The use of the s server is to be a choke off up for the graduation exercise server and withal to record orders from the customers. This does not re ad numerous risks as the orders can be accepted on an e-mail connection and they are quite safe for the users.\r\nFurther pencil eraser can be ensured through right off for sale. The size of e-mail connections are also large at present, of the order of 1GB and can be made even larger. At the send-off of the working solar day, employees can be asked to place down orders received from the Internet to the computer of the store. The time has already been decided as existence 11 am. All the orders can be placed in order and wherefore(prenominal) prepared for execution. If the execution of orders are correct before the end of closing hours, and then further orders, if any are in stock(predicate) on the e-mail site, can be taken up for execution. This litigate is broadly speaking safe.\r\nThe only difficulty comes from false orders, but that can be checked through a paying mechanism affiliated to the delivery part. When the order is delivered, the store go forth definite ly collect compensation, and this can be through a bank payment wait on, credit card or some other mechanism. When the order is sent to the store, an effectiveness should be sent by the purchaser to the paying party also. This can be checked by the store, before delivery. If the visible is to be collected from the store, then, the problems are little as the consumer will have to make payments directly.\r\nPurchases for a small store are difficult and often require expertise which the individual store whitethorn not possess. The solution that is often reached is to become a member of a buying gathering who will act as the buying organization for all stores, though the stores may be owned by incompatible persons. Buying groups exist in much all segments of the retail industry and some of the groups provide run in term of product charge and obtaining discounts for the stores through the process of summing up all quantities required and thus obtaining discounts for wholesale purchases.\r\nEven in the global scene, there are buying groups. Those organizations often have buying units distributed all over the world. (Varley, 36) In the long run, the exercise of computerization should not disturb this angle and the active method of purchases can still be retained. The advantages will come from the fact that as soon as sales are made, or orders executed, a record can be updated for the item in question. The sizeableness in this aspect is only for items in â€Å"A” category after an abstract of the items for sales through an ABC analysis.\r\nFor those items, since they involve an importance in terms of customer satisfaction, or investment, it is essential that a abutting record be kept. It is also possible, exchangeable Amazon to collect some of the big-ticket(prenominal) items on a day to day basis. These are decisions for executive instruction to consider. If the feeler to the store by the purchasers is only through e-mail, then they have no knock of directly collecting the information from the stores computer, but through certain bugs that may be placed in the computer along with orders.\r\nThis is a problem that comes even when the computer user visits certain sites, and can be wiped out through the use of anti-virus package and proper design of the computer organization. The biggest demonstrate to remember is that most users now use Internet Explorer as their verbiage for communication with Internet since they have the radical language as Windows. On the other hand, the store may use Mozilla Firefox for communication with Internet. This will automatically knock out a lot of infections. Apart from this are for the computer to be working on a non-windows agreement and this can be done through some computer programming in Java.\r\nThe details will have to be worked out with a computer expert. If the information of the company is stored on a different disk also, the chances of removal are much lower. This is not so difficult since the question of disks is only of virtual legal separation through programming. At the same time, it is also important to note that secrets about the organization also should not be available to internal users within the company unless they are permitted access. This can be controlled through requirement of passwords for entering those sections, but at the same time, the users will have to be studious about storage of the passwords.\r\nTo an comp allowion, the problem of painting of passwords can be controlled through changes of passwords on a regular basis. The job of a network decision maker involves many tasks and to an extent the tasks are also decided by the experience of the administrator in the job. The first step is to create its design, and this job has to be done by a fourth-year network architect. Since this network has been operating for some time, one presumes that it has a network administrator who has been in charge of the system, and this person, if he is informed enough with computers will be able to decide on its required involution.\r\nThe siemens set of responsibilities of the network administrator begins after the network is knowing and this involves setting up and configuring the network. It is important to remember that due to the complications of the network this may take some time, and, in general the old system should be permitted to continue till the new system is tested and ready. Then the switchover can be done within a on the spur of the moment period of a weekend or so. This will cause the least heart of disturbances to working. (Responsibilities of the Network Administrator)\r\nAfter all the store has to sell and earn money and computers are only assistance and cannot be permitted to come in the way of operations. The job now includes installing the physical aspects of the changes, configuring the files or databases, multitudes, routers and network configuration servers. The third phase of netw ork administration security involves regular tasks that have to be done †adding new host machines, direct administration, administration of network services and trouble shooting problems that are seen to arise.\r\nIn this case, the problem seems to be one of adding new hosts and increasing services of the network for which more than bundle package is expected to be wanted. (Responsibilities of the Network Administrator) This is however and ongoing process and one success will lead to other and this will require changes not intend in the earlier phase. In this case, let us say that the plan of expansion succeeds in satisfying the customers, and adds profits for the organization, and then a second store may be required.\r\nFor this sort of problems a regulation of redundancy should be built into network figure. From the general, let us get into the particular(prenominal) and all organizations involved with computer software have their own recommendations for network servi ce and Microsoft talks about it including Dynamic armament Configuration Protocol or DHCP, Windows Internet Name Service or WINS and area Name System or DNS. These are all software and part of these may massage the egos of the owners of the system, but whether they are indispensable or not will have to be determined by those designing the system.\r\nMicrosoft has made a system management function which provides guidance for the operation of the preceding(prenominal) named services and for maintenance of the hardware which will hold these programs. There is also a guide for getting required software for this purpose. (Service Management Functions: Network Administration) Considering the number of updates that come in for Windows, it does not seem to be very reliable software. There are also software designed for many different users and in these many users can work on the system at the same time and maintain files. An example of such a system is IRIX.\r\nThe only problem is that this system permits the workstation to be committed to networks and permits transfer of files from one to the other. (Overview of System Administration) Does this system require this facility, or will it be a source of trouble? The point is that all systems have to be designed according to the requirements as deemed fit by the management and first the thought of the management have to be clarified. To conclude, computers are the up-to-the-minute tools for the egos of today, but, at the same time, one should not end up with a system having a lot of useless or dangerous facilities.\r\n'
