Short Description

Attention: The admission for computer science is restricted for the winter semester 2022/23 for the first time. This means that your application must be submitted by July 15, 2022.  

Computer Science involves information and automatic information processing. It is a fundamental science deeply rooted in mathematics, physics and electrical engineering. In this Bachelor’s degree programme, students learn the theoretical and practical basics of Computer Science and a selection of subsidiary subjects. Students gain a solid grounding in the foundations of software and hardware. Programming is just one element of the Computer Science degree programme. Relevance to practice plays an important role throughout the programme. Building on sound basic knowledge, students may specialise in a wide range of subjects related to Computer Science, such as internet technologies, information systems, simulation and computer architecture.

Areas of Focus

  • Computational health informatics
  • Databases and information systems
  • Data science and digital libraries
  • Information retrieval and intelligent systems
  • IT security and human-computer interaction
  • Real time systems and energy informatics
  • Software engineering and simulation
  • System and computer architecture
  • Theoretical computer science
  • Visual analytics and knowledge-based systems
Course Content

In the course of the first three semesters, students mainly learn the fundamental principles, concepts and methods of computer science, as well as the necessary basic knowledge of mathematics and electrical engineering. In the further course of the programme, students can specialise to suit their individual interests. Students can choose from a large number computer science subjects: Operating Systems, Computational Health Informatics, Data Mining, Database Systems, Real Time Systems, Energy Informatics, Information Systems, Internet Technologies, IT Security, Artificial Intelligence, Man-Computer Interaction, Modelling, Logical Design of Digital Systems, Parallel Computing, Computer Architecture, Simulation, Software Engineering, Theoretical Computer Science, and Distributed Systems. Students may additionally take a subsidiary subject (e.g. Business Administration, Cartography and Remote Sensing, Mechanical Engineering and Mechatronics, to name just a few) that establish a connection to later employment. Leibniz Universität Hannover’s lecture programme (Studium Generale) also enables students to touch on other university disciplines beyond their chosen subject. The Bachelor’s degree programme ends upon completion of the Bachelor’s thesis in the sixth semester.
