Technology Product: Product Development
TCP/IP is the universally-accepted standard for internet-working protocol suites. However, despite its wide use, popularity, and inherent advantages, TCP has one fundamental drawback -- it is not as effective in high-latency environments as it is in terrestrial networks. This analysis sought to address this problem by i) developing a new product with better functionality in high latency, satellite environments; and ii) developing an effective development and marketing plan to ensure the product's successful diffusion into the consumer market. The analysis established that one of the reasons why TCP underperforms in satellite environments is because the congestion window does not open fast enough to support the long RTT links characteristic of such environments. For this reason, it proposes the development of an alternative protocol with a congestion window comprising of four segments as opposed to one (as is the case in TCP), to speed up communication in high-latency environments. The subsequent sections then focus on showing how marketing, pricing, and testing will be carried out to ensure that the launched product meets the exact needs, specifications, and requirements for which it was designed.

Introduction
First used as a research project by the Defense Advanced Research Project Agency (DARPA) in 1969, the TCP/IP protocol suite has evolved into the universally-accepted standard for internetworking protocol suites. The primary goal driving its design was the need to establish a suite of protocols capable of connecting diverse types of computer networks, designed by different manufacturers and running different operating systems (Miller, 2009). Achieving this goal has contributed to its growing success over the years; at present, TCP/IP is the world's most widely-deployed communications protocol suite, providing a base for high-level protocols including NFS, X11, FTP, and TELNET. Thanks to its non-proprietary and open nature, TCP/IP has continually gained popularity among UNIX Operating System users.
Background
Networking is one of the key-most features of computer applications; all communication protocols are developed with the aim of improving the existing ones' networking capabilities (Miller, 2009). Two decades ago, proprietary networking protocols such as DECnet were very prevalent; however, these were largely unable to link up different computer networks without the use of a translator. As the number of computer manufacturers grew, it became apparent that there was need to develop standard protocols that could effectively communicate with each other regardless of the type of operating system. This was when the TCP/IP protocol suite was developed, essentially allowing dissimilar systems to communicate with each other through a common language. Today, a Microsoft-powered PC is able to communicate effectively with a Dell Web server or an Apple Mac, all thanks to the non-proprietary nature of TCP/IP. Besides its open and non-proprietary nature, TCP/IP has several other features that boost its networking capabilities. These include an integrated addressing system that allow for communication between devices regardless of how each one is constructed; a design-for-routing system that enhances information routing across an arbitrarily complex network; network independence that allows it to function on lower-layer technology including WANs, wireless LANs and LANs; and a high degree of scalability.
From this background, TPC/IP may appear as the perfect solution for the 21st century networking. The truth, however, is that despite its inherent strengths, TCP/IP has one fundamental drawback -- its communication capability in high-latency environments is low. For instance, it takes less than 30 milliseconds to communicate information between New York and Los Angeles on a terrestrial network, but more than 500 milliseconds on a geostationary satellite link, which is taken in this case to represent a high-latency network. This is rather dangerous given the rising prevalence of global business, and the fact that organizations are increasingly communicating with their subsidiaries across border on high-latency networks. If TCP/IP is to remain relevant in the internetworking environment in future, necessary modifications will have to be made to improve its functionality.
Based on this drawback, I propose to set up a design team to address this matter from either an incremental perspective (designing suitable modifications to improve the functionality of TCP/IP in high-latency environments) or an innovative...
Creative Business Practices: Entrepreneurship Innovation and the Relevance to the Modern Organization The work entitled "Globalization of Social Entrepreneurship Opportunities" reports that entrepreneurship "...by new and established companies is a major source of wealth and job creation, economic and technological growth and social transformation. This transformation is made possible by the powerful forces entrepreneurship unleashes, where ordinary people conceive innovative ideas, organize production, assume risk, and engage customers to accumulate wealth
The "driving forces" that are fueling growth in the PHS industry are not unique, but they have been focused on an "innovation process [that] often leads to changes in market structure composed by varied players, and the appearance of novel services in the market" (Gao & Damsgaard 2007, p. 185). Not all industries have shared the positive experiences of the mobile telephone industry in China, though, and a number of

Engineers should focus on the improvement of the performance of the economy. This relates to the transformation of the theories of controlling the world and adopting new frameworks in the operating in conjunction with the planet. New engineers need to adopt and implement new theories of focusing on the economic, social, and political concepts in relation to both technical and nontechnical disciplines (Cameron 2010 p.40).

Three years later, the company improved its picture clarity and introduced the "emotional intonation" feature, considered important components of visual language. But at present, only 10% of the deaf and hard-of-hearing know about VRS. The Internal Revenue Service refuses to accept VRS calls. And VRS can be performed only with high-speed internet access. But companies, like Sorenson, provide videophones for free. Those who have no high-speed internet access or
