Narratives of Difference and Belonging Assignment

Narratives of Difference and Belonging - Assignment Example Interesting fact, illuminating statement, personal connection: An interesting fact mentioned in the article is that of the presence of the same set of things, starting from consumer products, to eateries, groceries, and shopping malls, which are seen everywhere in today’s globalized world. So there is a definite loss of individualism or uniqueness of a certain place, and one always ends up getting the same thing anywhere they go. This is something we are evidencing today in all parts of the world. There is always a McDonalds, a Cafà © Coffee Day or a Barista, and somehow the local flavor is slowly disappearing under the burgeoning pressure from these huge multinationals. I can personally connect to this observation, as wherever I have traveled looking for new things, I have always met these giants standing tall, dishing out the same set of standardized products. Author’s perspective/value position: The author feels that in this changed scenario of globalization and high-tech communication era, the youth needs to be first acknowledged as a source of power. Accordingly, their education should be offered in a different manner, inculcated with new values that would be more fitting in this hybridized world. To make this effective, the educators have to change their mindset or else as the author comments â€Å"We need new ways of thinking of and working with kids, otherwise we will become irrelevant as we produce education for categories of kids that no longer exist in the postmodern world† (Besley, 74). Validity/usefulness of the article for thinking about issues of cultural diversity: This article is very important in today’s context, as it speaks of the new age culture that we can see all around us.

Network Processes - Essay Example Nevertheless, the fundamental process remains same and heavily depends on the seven layers of Open Systems Interconnection (OSI) model and four layers of TCP/IP protocol stack. The OSI is a hypothetical model and provide the fundamental understanding of the communication infrastructure for modern networks. On the other hand TCP/IP is a suite of protocols which operates over this hypothetical model. In simplest words, protocol is a set of agreed upon communication rules that govern the communication between two or more machines. The OSI model and TCP/IP protocol suite work in close coordination at various layers to ensure a secure and efficient data communication. In majority of implementations, a sound understanding of the layers, protocols, processes and underlying technologies is required to appreciate the process that may occur in a network. Comer (2004) states this fact, â€Å"Understanding the internet technology requires one to distinguish between the low-level mechanisms prov ided by the hardware itself and the higher-level facilities that the TCP/IP protocol software provides†. Present day networks are so big and wide spread that they cannot be owned by a single business entity rather multiple entities look after their part of network to bridge the gap between various far of networks. Various issues surrounding the communication processes need in-depth investigation of the entire channel to find out the technicalities and interoperability potential of these layers and protocols. These layers and protocols are discussed at length in the following lines; A remote user starts this process by accessing the X-Stream Server through internet explorer. This access request is interpreted at Application Layer, by Hyper Text Transfer Protocol (HTTP) and it is destined for HTTP Port 80 at X-Stream Server. However, it must be noted that HTTP neither know the location of the server nor the routing details; it is the Transmission Control Protocol (TCP) implement ation in the backdrop which takes care of actual transmission. Tanenbaum (2004) while pointing out the role of HTTP states, â€Å"It specifies what messages clients may send to servers and what responses they get back in return. All clients and all servers must obey this protocol. The value of using TCP is that neither browsers nor servers have to worry about lost messages, duplicate messages, long messages, or acknowledgements. All of these matters are handled by the TCP implementation†. Another significant impact of TCP transmission in the physical network, is the level of abstraction it has to offer. TCP ensures the reliable and efficient transfer of the data, no matter what physical network layout exists between the client machine and the server. Moreover, it is the last layer before data leaves a user machine for onward dispatch to network layer which falls in the domain of Internet Service Provider (ISP), except for the case of an Intranet implementation at either side of the network. At this stage, it will be prudent to get into the detail of various layers of OSI Model and TCP/IP protocol stack. OSI Model has a seven layer structure as oppose to four layer stack of TCP/IP, however both have sufficient commonalities for sustainable interoperability and coordination, a layout diagram for both is drawn here for better understanding; It is evident from this diagram that the Application Layer in TCP/IP is the combination of three upper layers of OSI Mode
