Have you ever thought about how often you turn to the Internet throughout the day? Whether it be ordering a book or ticket online, checking the latest news or writing an email, everyday life without the Internet is nearly unimaginable. But wouldn’t it be nice to know how all of this is possible? This course will teach you about the technological foundation of this worldwide network. You will learn about its physical foundation of data transmission based on the functional principles and technologies of local area networks (LANs) and wide area networks (WANs). The TCP/IP reference model – the “heart” of the Internet – and its protocols and countless applications, will be presented in the units to follow. Participants will gain comprehensive insight into the complex world of Internet technologies. In clear terms, you will receive the knowledge to unlock the mysteries of the Internet.

Professor Dr. Christoph Meinel (Univ. Prof., Dr. sc. nat., Dr. rer. nat., 1954) is Scientific Director and CEO of the Hasso Plattner Institute for Software Systems Engineering GmbH (HPI) . He is a full professor (C4) for computer science and holds a chair at HPI on Internet Technologies and Systems . His areas of research focus on future Internet technologies, in particular Information Security, Web 3.0: Semantic Web, Social and Service Web, as well as on innovative Internet applications, especially in the domains of e-learning, tele-teaching and tele-medicine. Besides, he is scientifically active in the field of innovation research Design Thinking. His earlier research work concentrated on the theoretical foundation of computer science in the areas of computational complexity and the design of efficient (OBDD-based) algorithms and data structures.

Christoph Meinel teaches in the Bachelor and Master courses in IT-Systems Engineering and at the HPI School of Design Thinking. He is honorary professor at the Computer Sciences School at Beijing University of Technology, visiting professor at Shanghai University in China, and a senior research fellow at the Interdisciplinary Centre for Security, Reliability and Trust (SnT) at the University of Luxembourg. Since 2008, together with Larry Leifer from Stanford University, he is program director of the HPI-Stanford Design Thinking Research Program. Since 2010, he chairs the Steering Committee of the HPI Future SOC lab .

Christoph Meinel is author/co-author of 10 books and 4 anthologies, as well as editor of various conference proceedings. More than 400 of his papers have been published in high-profile scientific journals and at international conferences. His high-security solution Lock-Keeper is internationally patented and licensed by Siemens AG. His tele-TASK system provides an innovative mobile system for recording and Internet broadcasting lectures and presentations used in many universities all-over the world. The virtual tele-lab for Internet Security provides the possibility to get hands-on experiences in practical issues of Internet and information security. The recently developed tele-Board supports remote work of creative teams.

Christoph Meinel is a member of acatech, the German academy of sciences and engineering. He is chairman of the German IPv6 council and of the advisory board of UTD Meraka in South Africa, and a member of the SAP Security Advisory Board. In 2006, he hosted together with Hasso Plattner the first German "National IT-Summit" of the German Federal Chancellor Dr. Angela Merkel. From 1998 to 2002 he was the founder and CEO of the Research Lab "Institute for Telematics" in Trier. Christoph Meinel is chief editor of the scientific electronic journals ECCC - Electronic Colloquium on Computational Complexity and ECDTR - Electronic Colloquium on Design Thinking Research , the IT-Gipfelblog , and the tele-TASK archive.
