Module Technologies of the Internet, Media Computer Science (Bachelor) (ER 4)
Students acquire comprehensive knowledge of techniques and concepts in distributed systems, particularly in the context of web applications. They understand the general architecture of the Internet and the Web and are able to analyze the requirements of web applications accurately. They can develop interactive web applications using HTML, CSS, and client-side JavaScript, as well as implement server-side code for application services, including authentication, cookies, and session management. In addition, they are able to identify potential security issues such as cross-site scripting and SQL injection and implement appropriate protective measures. These skills enable students to design, develop, and operate complex and secure web applications effectively.
The course provides a practical introduction to the concepts and paradigms of distributed systems using the example of web technologies and application development on the web. This initially involves an introduction of the world wide web with basic protocols such as HTTP and other standards in the context of the Internet. After that an introduction to the design and construction of web applications is provided. This includes firstly the frontend development with HTML5, CSS3 as well as client-side JavaScript and secondly the backend development with server-side JavaScript on the Node.js platform. Interactions between frontend and backend follow modern REST/HTTP and AJAX techniques. In addition, mechanisms for personalization with cookies and sessions as well as to authenticate users are presented. The course closes with a detailed discussion of web application security.
Upon completing this lecture class, students will acquire practical skills in the development and deployment of web applications, grounded in an understanding of distributed systems and web technologies. They will learn to proficiently use HTML5, CSS3, and JavaScript for frontend development, alongside server-side development with Node.js, enhancing their ability to create dynamic, full-stack web applications. Additionally, students will gain knowledge in implementing modern REST/HTTP and AJAX techniques for efficient frontend-backend communication, as well as in employing cookies, sessions, and authentication strategies for personalizing user experiences and ensuring application security. This comprehensive skill set will prepare students for a wide range of roles in web development and application design, equipping them with the necessary tools to address current and future challenges in the field.

- Additional literature will be announced during the lecture
In preparation for individual lecture units, the self-study of basic content is required by means of the accompanying literature (relevant chapters will be announced in the event). Further independent work concerns the follow-up of the lecture contents and the exam preparation.
The lab course covers the practical application of various basic web technologies. The selection of technologies follows the topics of the VS1 lecture. In the laboratory, a complete web application is created in several steps. Each step takes a closer look at a range of web technologies. This will specifically promote skills in understanding and applying Web technologies including the areas of declarative languages such as HTML, CSS, and JSON, client-side and server-side JavaScript programming, and special technologies for single-page applications and REST architectures.

- Additional literature will be announced during the lecture
Basic knowledge of general programming and declarative web languages is required (the latter can be obtained by a limited self-study of the accompanying literature). The course includes 50% supervised presence time (1 SWS) in the LKIT lab and 50% individual work. Proof of achievement is provided by presentation and defense of the solution.
This course provides students with the theoretical and applied knowledge about the creation of media-based web applications. This includes the foundations of the markup language HTML and Cascading Style Sheets, how to embed different types of media, as well as the conception, design and programming of responsive web applications.
