- Abstract
- Die meisten von uns kennen den Frust, vor dem Bildschirm zu sitzen und zu warten, bis endlich ein Bild stückweise und ruckartig zu erscheinen beginnt. Bilddaten sind so riesig, dass sie auch gute Datenkanäle zustopfen. Dies zu verhindern oder mindestens deutlich einzugrenzen, führt zu mathematisch interessanten Modellierungs- und Optimierungsproblemen

- Abstract
- Da der Computer mittlerweile in fast alle Lebenesbereiche eindringt und immer neue Anwendungen für die Verarbeitung digitalisierter Informationen erschlossen werden, schwillt der Strom des Datenverkehrs zwischen Rechnern unterschiedlichster Art immens an. Ihn auch zukünftig zu bewältigen, bedarf es besserer Verbindungswege

- Abstract
- Während in den 80er und zu Beginn der 90er Jahre Überwachungsverfahren und die Verletzlichkeit der vernetzten Informationsgesellschaft Gegenstand alternativer Technikkritik waren, scheinen die damit verbundenen Gefahren mit der Verbreitung des Internet weitgehend verflogen zu sein. Zumindest findet ein diesbezüglicher Diskurs kaum statt, und auch Kritiker sind zu begeisterten Nutzern geworden. Interessanterweise ist jedoch gerade das Internet ein in mancher Hinsicht unsicheres und datenschutzunfreundlicheres Netz als früher kritisierte Netze und Dienste, wie etwa ISDN oder BTX. Das technische Netzkonzept und die Organisationsform seines Betriebs lassen zentral organisierte Grundschutzkonzepte wirkungslos werden, so daß hier viel vom Selbstschutz der Beteiligten abhängt. Diesen zu stärken, wäre ein wichtiges technologie- und gesellschaftspolitisches Ziel der kommenden Jahre

- Abstract
- Der Autor geht der Frage nach dem Einfluß der Normung auf die Kommunikationstechnik und ihrer sozialen Akzeptanz nach. Hierzu zeigt er die Strukturen der Normungsprozesse und der Gremien insbesondere in Europa auf. Am Beispiel der Normen zu elektronische Postsystemen führt er auf, wie weit die Normung in diese Systeme hineinreicht und welche kommunikationsrechtlichen Probleme damit verbunden sind

- Abstract
- Bei den Überlegungen, das Dienstleistungsangebot der Bibliotheken auszuweiten, spielt der Zugang zu nationalen und internationalen Netzen und damit der Zugang zu online verfügbaren Informationen eine immer größere Rolle. Für die Auswahl des Netzes müssen sowohl die einmaligen Ausgaben für die technische Ausstattung und Zugangsberechtigung als auch die monatlich wiederkehrenden Ausgaben für die Nutzung berücksichtigt werden. Für die Entscheidung sind aber auch Übertragungsgeschwindigkeit, angebotene Dienste auf dem Netz, Kommunikation mit anderen Netzen und die regionale Erreichbarkeit des Netzanbieters von Bedeutung

- Abstract
- Virtuelle Welten - eine neue Dimension in Datennetzen. Neben der Möglichkeit, sich mit Hilfe von Datenhandschuh und -helm in computergenerierten Räumen zu bewegen und Abenteuer zu erleben, bilden virtuelle Räume im WWW eine erweiterte Navigations- und Präsentationsmöglichkeit für Informationssysteme. Auf der Basis einer breitbandigen rechnergestützten Kommunikationsinfrastruktur wie den DFN kann ein bestimmtes Thema - hier ein Stadtspaziergang durch Hannover - mit der Kombination von 2- und 3-dimensionalen Navigationselementen dem Betrachter nahegebracht werden

- Abstract
- Überblick über die Datennetze im Forschungszentrum Jülich. Im Mittelpunkt steht dabei der Zusammenhang zwischen den speziellen Anforderungen und Anwendungen eines zentralen Informationsdienstleisters (Zentralbibliothek) und der daraus resultierenden Gestaltung und Strukturierung der Datennetze. Es wird gezeigt, daß die zukünftige Netzlast der Informationsgesellschaft im Zeitalter von Multimedia nur mit modernster Lichtwellenleitertechnik zu bewältigen ist

- Abstract
- Die 10 Hauptkapitel enthalten verständlich geschriebene, aktuelle Übersichten mit vielen Visualisierungen zu aktuellen Fragen der Telekommunikation (zum Beispiel zu neueren Trends, zu kommerziellen Perspektiven des Internets und zu Erfahrungen regionaler Projekte). Das Produkt liefert eine in dieser Form auf dem MArkt nicht verfügbare Übersicht für alle am Thema Interessierten. Er ist besonders nützlich für Praktiker in Unternehmen (Weiterbildung) sowie für Schüler, Lehrer, Studenten und Professoren. Die Dokumente liegen im HTML-Format vor und können auch in den Formaten Winword ab 6.0 und Powerpoint ab 7.0 geladen und weiterverarbeitet werden. Die 10 Kapitel behandeln die Themen: Visionen für die Zukunft, Zukünftige Märkte und Strukturveränderungen, TK-Anbieter und ihre Dienste, Einführungin die Internet-Praxis, Online-Dienste und Internet-Provider, Kommerzielle Perspektiven des Internet, Regionale elektronische Gemeinschaften, Telearbeit als neue Arbeitsform, Politische und rechtliche Rahmenbedingungen, Telekommunikation in der Kritik

- Abstract
- Der Aufsatz untersucht das Z39.50 / SR Protokoll und seine Client/Server Umgebung. Die Funtionalität des Z39.50 und die Anwendung in Netzwerken wie dem Internet wird diskutiert. Die Anwendung des Z39.50 in Bibliothekssystemen wird dem Benutzer einfachen und plattformübergreifenden Zugriff auf Informationen bieten. Das Protokoll schafft eine Benutzerumgebung, die anbieterunabhängig arbeitet
