University IT and Data Center

The University IT and Data Center (Hochschulrechenzentrum, HRZ) is the central IT service provider of the University of Bonn

Girls'Day 2023 at the HRZ

How does one create a web page with HTML? How does one set up a website in a local network? How can a server be effectively secured? How does a 3D printer work?

This year, for the first time, seven girls between the ages of 13 and 16 were able to find answers to these and many other exciting questions at the University Computer Centre of the University of Bonn as part of the Girls'Day 2023.

Highlights included a demonstration of the in-house 3D printer and a tour of the HRZ's server rooms. After brief theoretical introductions to various IT topics in the morning, the girls were able to put what they had learned into practice in the afternoon: in an interactive phase, they designed their own websites on the topic of "University buildings in Bonn". The results were impressive and could even be taken "home" via QR codes printed on playing cards to be presented to family and friends. At the end of the day, the specially created golden Girls'Day-at-the-HRZ medals could be collected from the 3D printer - a great reminder of an exciting day at the University Computer Centre of the University of Bonn!

"It was a successful day for everyone involved," says Karin Ahorner, who was responsible for the planning and implementation of the Girls'Day 2023 at the HRZ, "and we are pleased that we were able to get the girls excited about IT topics and working at our HRZ, in the hope that we can make an active contribution to increasing the quota of women in the IT sector, especially in the area of trainees."
