Das Internet hat die Kommunikation der Menschen im Alltag und Geschäftsleben grundlegend verändert. Die digitale Kommunikation in den sozialen und mobilen Netzwerken überlagert die traditionellen Kommunikationsformen und prägt eine neue soziale und betriebliche Wirklichkeit. Wie aber funktioniert die digitale Kommunikation, welche Möglichkeiten und Grenzen einer programmierten Welt bietet sie? Um zum Beispiel verbindliche Transaktionen abzuschließen oder eine intelligente Suche zu ermöglichen, ist es notwendig, die syntaktische Form von Daten zu erfassen und ihren semantischen Gehalt zu erschließen. Die Theorien der Kommunikations- und Sprachwissenschaft in Kombination mit der Informatik und Wirtschaftsinformatik sollen dieses Wissen bereitstellen. Dazu behandelt das Buch Digitale Kommunikation die folgenden Themen: Syntax, Semantik und Information Algorithmen, Informationsmodelle, Rekursion, Funktionen, Church-Turing, Halteproblem Sprache, Universalienstreit, Wittgenstein, Sprechakttheorie, Domänensprachen Sicherheit und Datenschutz, Vertraulichkeit in betrieblichen Anwendungen, Kommunikationswissenschaftliche Modelle Shannons mathematisches Modell der Übertragungskanäle Das Internet-Referenzmodell (OSI 7 Schichten und Internet 4 Schichten) Kommunikationsprotokolle und Datenformate von E-Mail, Web und E-Commerce Prof. Dr. Rüdiger Grimm war 2005-2015 Professor für IT-Risk-Management im Fachbereich Informatik der Universität Koblenz-Landau und ist seither in Ruhestand. Weiterhin nimmt er dort Lehr- und Projektaufgaben wahr und ist gleichzeitig wissenschaftlicher Berater und Ombudsmann im SIT - Fraunhofer Institut für Sichere Informationstechnik in Darmstadt. Seit 2010 ist R. Grimm Fellow der Gesellschaft für Informatik GI e.V. 2000-2005 war er Professor für Multimediale Anwendungssysteme an der Technischen Universität Ilmenau und Forschungsgruppenleiter im Fraunhofer-Institut für Digitale Medientechnologie. Davor hatte er in der GMD Darmstadt wissenschaftliche Aufgaben im Aufbau des Internet und insbesondere für seine Sicherheit im Rahmen des Deutschen Forschungsnetzes wahrgenommen und in der Universität Frankfurt Vorlesungen über IT Sicherheit gehalten. PD Dr. Patrick Delfmann ist seit 2015 Vertretungsprofessor für Betriebliche Kommunikationssysteme im Fachbereich Informatik der Universität Koblenz-Landau. Er lehrt und forscht dort in den Bereichen Kommunikationssysteme, Geschäftsprozesse und Predictive Systems. Zuvor war er als PostDoc am European Research Center for Information Systems (ERCIS) der Westfälischen Wilhelms-Universität Münster tätig. Neben seinen Haupttätigkeiten in Münster und Koblenz hat er zahlreiche Gastdozenturen, u. a. in Moskau, Wien und Osnabrück übernommen.

"Until now, no book has adequately treated all engineering aspects of microwave communications in the digital age. This important new work provides readers with the depth of knowledge necessary for all the practical engineering details associated with fixed point-to-point microwave radio path design: the why, what, and how of microwave transmission; design objectives; engineering methodologies; and design philosophy (in the bid, design, and acceptance phase of the project). Written in an easily accessible format, the book is complete with an appendix of specialized engineering details and formulas.?"-- "Integrated use of industry leading microwave path engineering software to solve problems introduced in the book"--

How does social media affect working life in Higher Education? How are universities harnessing its power to aid student learning? This innovative collection brings together academics and those working in professional services to examine these questions and more. The diverse and expert contributors analyse the many ways social media can be used to enhance teaching and learning, research, professional practice, leadership, networking and career development. The impact of social media is evaluated critically, with an eye both to the benefits and the problems of using these new forms of digital communication. This is the first volume to give such detailed attention to this area of high interest. Its innovative approach extends to its creation, with contributors found via their presence on Twitter. The short and impactful chapters are accessible while retaining an academic focus through their application of relevant learning theories and educational context. Social Media and Higher Education is essential reading for any professional working in higher education, including lecturers teaching education courses. It is also significant for researchers looking at more recent developments in the field and what it means to work in a modern higher education environment.

Nowadays, we live in an interconnected world. Through the Internet and new technologies, we all have access to an abundance of information everywhere and all the time. As a result, this has changed consumers behaviour. The way businesses interact with their customers has also changed dramatically. 

Startups, which often have budget, time or knowledge constraints, should take advantage of the Internet, social networks and all these new means of communication, which are often affordable. Therefore, this study tries to understand how they communicate with their customers and potential customers through digital ?

This research work is based on a literature review followed by an exploratory qualitative study. In this study, ten Belgian or Luxembourg startups revealed their way of communication, their reasons and motivations for using specific tools. Also, their barriers and their expectations for the future with regard to their communication were explained. We had the possibility to compare their answers, make links with the literature review, and try to understand their choices.

At the end of this research, startups we met revealed to us that they are aware of the need to be present on the Internet. They proved that they were establishing concrete actions in order to be active on the Internet. However, despite these efforts, most of them realize that they have things to improve and install in order to be even more efficient in terms of digital communication. As a result, with the complementarity of primary and secondary data, a non-exhaustive list of recommendations for these startups has been proposed to startup managers in order to take advantage of this digital communication.
