Studienarbeit aus dem Jahr 2016 im Fachbereich Informatik - Software, Note: 1,0, AKAD University, ehem. AKAD Fachhochschule Stuttgart, Sprache: Deutsch, Abstract: Die Problemstellung und somit auch Hauptziel dieser Arbeit ist die Darstellung des Weges einer elektronischen Nachricht durch die Infrastruktur des World Wide Webs, des Senders und des Empfängers. Es handelt sich hierbei um sehr komplexe Vorgänge, welche das eigentlich "banale" Versenden und Empfangen einer E-Mail erst ermöglichen.In der heutigen Zeit spielt die digitale Kommunikation eine äußerst wichtige Rolle und ist im privaten wie besonders im geschäftlichen Bereich nicht mehr wegzudenken. Das World Wide Web, im Alltag oft fälschlicherweise mit dem Internet selbst identifiziert, versorgt uns mit Informationen und Diensten aller Art. Das World Wide Web besteht nicht nur aus mehreren Rechnern und TCP/IP dazwischen, sondern dahinter verbergen sich sehr komplexe Vorgänge die einen weltweiten Dienst zur Übermittlung nicht nur von Daten, sondern auch von audiovisuellen Informationen in Form von IP-Paketen darstellen. Vergleicht man diesen Dienst mit der Post, so würde ein IP-Paket einem Brief und die IP-Adresse einer postalischen Adresse entsprechen.
As internet has become a crucial element of Information Technology in our daily lives, so has the web search engine. Web search engines are formed with the reason to search information from the World Wide Web (WWW). This work proposes a new approach to rank web pages for search engines. This new method is an alternative to PageRank algorithm. It starts off by discussing in brief about the algorithm of PageRank, the mathematical background of PageRank and its role to rank web pages. Next, the book introduces a new method and formula to find the probability that can be used to rank web pages efficiently. The derivation of formula and how it is found is explained in details. The proposed methodology shows how it is not only dependent on backward link while ranking webpages. It also considers other entities of a webpage to rank a webpage. The data and results for this research are presented to prove how the new probability formula derived is efficient to overcome the backward overloading problem of PageRank.
This book provides a comprehensive treatment of the rapidly changing world of Web-based business technologies and their often-disruptive innovations. The history of the Web is a short one. Indeed many college graduates today were not even born when the Web first emerged. It is therefore an opportune time to view the Web as having reached the point of graduation. The Web has led to new ways in which businesses connect and operate, and how individuals communicate and socialize, related technologies include cloud computing, social commerce, crowd sourcing, and the Internet of Things, to name but a few. These developments, including their technological foundations and business impacts, are at the heart of the book. It contextualizes these topics by providing a brief history of the World Wide Web, both in terms of the technological evolution and its resultant business impacts. The book was written for a broad audience, including technology managers and st udents in higher education. It is also intended as a guide for people who grew up with a background in business administration or engineering or a related area but who, in the course of their career paths, have reached a point where IT-related decisions have become their daily business, e.g., in digital transformation. The book describes the most important Web technologies and related business applications, and especially focuses on the business implications of these technologies. As such, it offers a solid technology- and business-focused view on the impact of the Web, and balances rules and approaches for strategy development and decision making with a certain technical understanding of what goes on "behind the scenes."
Seminar paper from the year 2010 in the subject English - Applied Geography, grade: 1,7, University of Paderborn, language: English, abstract: 1. Introduction (What is the CW?) The term crisis is drastic but could be applied in the context of the current American television market. Due to the waste amount of online material spread all over the world wide web for free, online recording and TIVO, the financially necessary advertisement business is shrinking. The major networks (ABC, NBC, CBS and FOX) have a variety of shows that produce week after week solid ratings and high market shares but the young network The CW is struggling. This network launched at the beginning of the 2006-2007 television season and now after approximately three years it is time to take a closer look whether it has been a success or not. In the beginning The CW claimed to become the fifth major network in the US - let's check whether it was a prophecy or false hope. In order to accomplish that I will provide a brief historical overview of the network, the shows, its market placement and the website. [...]
Studienarbeit aus dem Jahr 2008 im Fachbereich Soziologie - Medien, Kunst, Musik, Note: 2,0, Europa-Universität Viadrina Frankfurt (Oder) (Kulturwissenschaften), Veranstaltung: Forschungscolloqium 'Migration und Minderheiten', Sprache: Deutsch, Abstract: The revolution in Information and Communication Technology (ICT) has contributed to the creation of the concept of the 'information - knowledge society'. As more and more information and transaction are being carried out online, computer and internet skills play an increasingly important role in our society. Since the mid 1990's the internet changes 'our' lives and became an important resource for accessing news and information, communication, distance learning, commerce, entertainment, job searching, civic participation, and government services. Unfortunately not everybody has access to take part in, and the benefit of the endless possibilities offered by the World Wide Web. The term digital divide, also called digital gap, refers to these inequalities. The term subscribes to the growing gap between those who have and those who have not. Where neither general access nor access to content that could benefit them economically and or socially is possible. Firstly, the following paper defines the phrase digital divide and describes the factors which limit and prevent the majority of world's population from taking part in the advantages of the 'information society'. With reference to Germany - as an example of the digital divide within developed countries -the causes, the population groups who are affected by this problem, and solutions to bridge the gap, will be briefly discussed in the second part of this paper. The main part of the assignment concentrates on an analyses of the different aspects of the global digital divide and focuses on disparities in internet access and use, mainly across developed ('information-rich') and developing ('information-poor') countries and regions in the world. Furthermore the paper describes how the lack of technology , the lack of skills, and of how limited access to technology, affects both the individuals and the population as a whole in regions where this digital divide is most evident. It also compares the possible perspectives of the cyber-optimists with cyber pessimists, given the development of the global digital divide and the directions it may take in the future. Finally, a brief overview will be given on the approaches and programs currently being instituted to narrow the global digital gap. With further research into new proposals and possible solutions, this could also contribute to the realisation of a global information society.
Telecommunications has had a major impact in all aspects of life in the last century. There is little doubt that the transformation from the industrial age to the information age has been fundamentally influenced by advances in telecommunications. Optimization problems are abundant in the telecommunications industry. The successful solution of these problems has played an important role in the development of telecommunications and its widespread use. Optimization problems arise in the design of telecommunication systems and in their operation. The Handbook of Optimization in Telecommunications brings together experts from around the world who use optimization to solve problems that arise in telecommunications. The editors made an effort to cover recent optimization developments that are frequently applied to telecommunications. The spectrum of topics covered includes planning and design of telecommunication networks, routing, network protection, grooming, restoration, wireless communications, network location and assignment problems, Internet protocol, World Wide Web, and stochastic issues in telecommunications. The editors&#8217; objective is to provide a reference tool for the increasing number of scientists and engineers in telecommunications who depend upon optimization in some way. Each chapter in the handbook is of an expository nature, but of scholarly treatment, and includes a brief overview of the state-of-the-art thinking relative to the topic, as well as pointers to the key references in the field. Specialists as well as nonspecialists should find this handbook stimulating and helpful.
