Distributed Networks - Essay Example e, the different peers provide the services and use the provided services [1]. Another difference between peer to peer networks is based on file storage and access; Client-server networks depend on a central dedicated server for file storage the clients then access the files from the server whereas in peer to peer networks file storage is in the different peers on the network. The security of the files in peer to peer networks is dependent on the end users while that of client-server networks is dependent on the server administrator. The server on a client server network provides secured access to the client thus providing better levels of security. Implementation of peer to peer network is much cheaper as compared to client-server because no centralized server is required [3]. Peer to peer networks have various benefits over other network architectures, they include; Peer to peer networks are cheaper to install as compared to other network architecture because no dedicated server is required for the network. Peer to peer is allows sharing of resources such as printers therefore saving on costs [4]. Installation and maintenance of peer to peer networks is easier because no network configurations are required. The peers on the network use individual operating systems. Peer to peer networks are more reliable because the devices on the network are independent i.e. they do not depend on a central server therefore failure of on peer does not affect the performance of the other peers [1]. Peer to peer networks save on time and resources because there is no need for a full time system administrator to manage a server [4]. The use of peer to peer networks has its own drawbacks, the disadvantages of this networks include; The security levels in peer to peer networks are limited thus there is likely to be transmission of viruses spywares and malware across the network [2]. In case of data loss it may be very difficult to recover because each peer on the network has its o wn backup system. Due to lack of centralized administration, it’s difficult to manage all the activities on the network. Peer to peer networks are good for small networks where high level of security is not required [3]. Some of the peer to peer tools currently available in the market include; Oversim- It’s an open source high performance simulation framework for peer to peer networks. It has an interactive user interface that visualizes network topologies messages and routing tables. Oversim simulation framework is flexible in its operations because it simulates both structured and unstructured overlay networks. Due to its high performance capability, Oversim can be used to simulate large networks of up to 10000 nodes and also has a network scheme that allows configuration of network topology with realistic bandwidths and packet relays which enhances its high performance [2]. Peerism is a java developed open source framework that was created to support large network s calability. Peerism is composed of two simulation engines

Middterm essY - Essay Example With regards to the exemplification of the first economic principle, consumer choice, this can relatively be defined in terms of the fact that the consumer continually wants more than he/she can provide. In essence, a desire exist within the current market for French fries; even though it is true that this food is very harmful to the health and weight of the individual in question. Yet as a clear and evident outgrowth of the fact that consumer demands know no bounds, the article references the fact that a clear and unmet demand exists for â€Å"low fat† French fries; something that none of the main fast food chains have moved towards supplying to the market. In this way, the article goes on to explain how Burger King seeks to lead the market by providing what consumers have been demanding. It is likely to assume that the move by Burger King to fill this shortage in supply of a commodity that consumers have actively been seeking will provide a level of profitability that other firms operating within the same markets have not had the presence of mind to fulfill (O’Connor 1). An additional economic principle that is referenced within the article in question is with regards to the fact that the consequences of consumer choice of live in the future. Whereas it is unfair to state that this economic principle has not been appreciated within the past, it can necessarily be seen could be more relevant with regards to the current situation and the way in which consumers are unequivocally more concerned with regards to the health and safety of the food products that they consume. Recent levels of environmentalism and the focus upon organic foods has led consumers to demand high-quality with regards to products they regularly integrate with. Likewise, seeking to tie this back in with the economic principle of the consequences lying in the future, the reader can easily discern the fact that continuing to assume French fries that are high in fat ultimately has a detrimental impact with regards to the future health and longevity of the individual in question. Within such a way, Burger King has leverage this understanding and seeks to utilize this level of forethought and planning as a means of selling an entirely new product; likely at a slightly higher rate than be alternatively less healthful traditional fries. Although the examples that have thus far been pointed out may seem as somewhat trite, the fact of the matter is that firms such as Burger King are intimately aware of the decision making structure and impetus that encourages the consumer to integrate with their product. In this way, seeking to understand these environmental factors and the recent push towards engaging anymore healthful lifestyle, firms are ultimately faced with two decisions. They can either continue to offer the product that they have offered in the past, to a great deal of commercial success, or they
