Fundamentals of Networking
Phase 2 Discussion Board

December 1, 2013 In this discussion board, I am going to define and describe the OSI and the TCP/IP models including a discussion on where and how they overlap. I will discuss why I think the TCP/IP model is use and the OSI model is not, and finally what my definition of the steps of OSI and TCP/IP are and their implementation. I am going to start with the OSI model. The OSI model is made up of 7 different layer, each with their own functions. Each of the layers are defined as: 1. Physical Layer:
The physical layer is responsible of delivering row bit stream over the physical cable. Its functions are physical medium transmission, transmission technique and data encoding. (Khani, 2012) 2. Data Link Layer:
The data link layer is responsible for controlling the error between adjacent nodes and transfer the frames to the other computer via the physical Layer. Its functions are Link establishment and termination, frame traffic control and frame acknowledgement. (Khani, 2012) 3. Network Layer:
The network layer is responsible for the translating of the logical network address and names into their physical address. Its functions are subnet traffic control, logical and physical address mapping and frame fragmentation. (Khani, 2012) 4. Transport Layer:
The transport layer is responsible for the end-to-end deliveries of messages between the networked hosts. Its functions are message segmentation, message acknowledgement session and multiplexing. (Khani, 2012) 5. Session Layer:
The session layer is responsible for establishing the process-to-process communication between the hosts in the network. Its functions are session establishment, maintenance and termination, and session support. (Khani, 2012) 6. Presentation Layer:
The presentation layer is responsible for the...

Business Communication

...Bus 220: Business Communication and Information Systems M8A1: Final Examination June 20, 2013 1. Explain virtual reality. Provide three examples. Virtual reality (VR) is a system “that enables one or more users to move and react in a computer-simulated environment.” (Stair & Reynolds, 2012, p. 337) Virtual reality applies sights and sounds in an artificial environment where human actions determine to an extent, what occurs inside the environment. Today, virtual reality is used in communication, training, and treatment in a spectrum of areas including the medical field, entertainment, and education. Medical VR systems “provide a new human-computer interaction paradigm in which users are no longer simply external observers of images on a computer screen but are active participants within a computer-generated 3D virtual world.” (G & B, 2002) Inside the world of virtual reality, medial applications such as three dimensional visualization of anatomy, telepresence surgery, complex medical database visualization, rehabilitation, surgical simulators and virtual surgical equipment as well as virtual operating rooms are emerging. Facilitated through computer interface, these medical applications of virtual reality are essential in the field of medicine. These applications allow individuals to learn human anatomy by “flying inside and around organs.” (Satava, 1995) The purpose of VR systems in the medical field is to ultimately develop a digital physician. ......

Moreover, Unmanned or Autonomous Underwater Vehicles (UUVs, AUVs), equipped with sensors, will find application in exploration of natural undersea resources and gathering of scientific data in collaborative monitoring missions. Underwater acoustic networking is the enabling technology for these applications. Underwater Networks consist of a variable number of sensors and vehicles that are deployed to perform collaborative monitoring tasks over a given area. In this paper, several fundamental key aspects of underwater acoustic communications are investigated. Different architectures for two-dimensional and three-dimensional underwater sensor networks are discussed, and the underwater channel is characterized. The main challenges for the development of efficient networking solutions posed by the underwater environment are detailed at all layers of the protocol stack. Furthermore, open research issues are discussed and possible solution approaches are......

Evaluate the Impact That Entrepreneurial Networks Will Have on the Novice Nascent Entrepreneur Setting Up Business for the First Time

...Evaluate the impact that Entrepreneurial Networks will have on the Novice Nascent Entrepreneur setting up Business for the first time Introduction The extent to which entrepreneurial networking has an impact on the nascent entrepreneur is an interesting hypothesis. There is evidence to suggest that the nascent entrepreneur is reliant on the use of networking, yet other evidence states that the success of this type of entrepreneur stems from contrary elements. "Entrepreneurial networks provide a framework for processes aiming at organising resources according to opportunities" (Johannisson & Monsted 1997, p109). This definition clearly states what the use of entrepreneurial networking sets out to do, and is supported by the assumption that networking is the "acquisition of entrepreneurial skills" (Martinez & Aldrich, 2011, p7). This report sets out to assess the impact of which entrepreneurial networking has on the nascent entrepreneur: "Individuals who are in the process of starting up new ventures" (Renko, 2012, p1045). In the following report, an investigation as to what classification of impact that entrepreneurial networking has on the entrepreneur will be assessed. Based on academic research, a definitive conclusion will be made and a judgement of the usefulness and level of impact these networks have will be assessed throughout. The report will take into account the difference between academic opinions, and note that many academics believe that......

...Cyworld Marketing Fundamentals (18-7-2012) ------------------------------------------------------------------------------------------------------------------------------------ 1. Problem Statement In mid 2007, Cyworld had increased to more than 21 million users from its 2.5 million in 2003. By the end of 2007, SK Communications had $197 million revenues and an operating loss of $0.35 million due to the acquisition of Empas. Cyworld accounted for 50% of total revenues and majority of operating profits. Almost 70% of Cyworld’s revenues were coming from selling virtual items to decorate user’s home pages but this source of revenue was starting to become exhausted so new revenue streams were needed. 2. Situation Analysis Company. Cyworld began as a simple social networking platform when it started in 1999. It initially provided a service that allowed users to build a social network of friends and not much more. The company’s goal was to offer users a “small, clean community,” which meant limited ads and an exclusive focus on social networking. However, as time passed, Cyworld eventually lost its original value proposition. By 2006, the company had become an open community, providing its users with a variety of services. Cyworld  was no longer just focused on social networking, it had become a site based on personal media (concept of a user creating a “minihompy” and Home2) and a media platform (open platform for media sharing).

Internet of Things

...Brazil Department of Electronics Engineering Hankuk (Korea) University of Foreign studies Global Campus: Yongin, South Korea Abstract – The Internet of things can be defined as to make the “things” belong to the Internet. However, many wonder if the current Internet can support such a challenge. For this and other reasons, hundreds of worldwide initiatives to redesign the Internet are underway. This article discusses the perspectives, challenges and opportunities behind a future Internet that fully supports the “things”, as well as how the “things” can help in the design of a more synergistic future Internet. Keywords–Internet of things, smart things, future Internet, software-defined networking, service-centrism, informationcentrism, ID/Loc splitting, security, privacy, trust. I. INTRODUCTION The Internet of things (IoT) refers to uniquely addressable objects and their virtual representations in an Internet-like structure [18][19][20]. We can say that it is an extension of Internet with uniquely addressable objects becoming a part of existing Internet. The objects forming the IoT will have distinct characteristics about them. They may hold selfidentifying information; they may even transmit the processed information or anything that may be considered important with respect to the object with which they are associated. There is a lot of pervasive presence in the human environment of things or objects, such......
