The last lecture on Friday afternoon will start with a small recap of what we have done over the last three weeks and some details on the projects. This recap is going to be very brief and will not reiterate the complete content of this course. Nevertheless, we will provide you with the opportunity to ask specific questions about any covered topic (we will not answer *broad* questions like "how does DHCP work"). If there are no questions, the Q&A phase will be very short, so please come prepared.

Introduction

Large-scale networks as the Internet are crucial for day-to-day communication, which also holds for near-field communication and personal area networks. In order to give a basic understanding and required practical skills, this course teaches networking concepts as well as programming and troubleshooting methods. Starting from the application layer, all parts and components of networks are explained, down to some of the physical aspects of wired and wireless technology.

The Telecommunications Lab at Saarland University is offering this course for the first time to teach networking fundamentals to undergraduates, as these topics are not part of the mandatory curriculum in Computer Science Bachelor programme.

Organization

  • Credit Points: 6
  • Format:
    • 3 weeks of lectures and tutorials (26. Sept. - 14 Oct. 2016)
    • 1 week of preparation for a small exam (14. Oct. - 19. Oct. 2016)
    • 2 weeks for implementing small software projects (14. Oct. - 04. Nov 2016)
  • Requisites:
    • Enough motivation and drive for taking part in a short but intensive course with many new concepts.
    • No networking knowledge required.
    • Elementary programming skills required (e.g. Programmierung 2, Programmieren für Ingenieure).
    • Python skills are beneficial, but there will be tutorials on that.

Curriculum
