Software is an integral part of the courses and is used to support data acquisition and control, data analysis, simulations of natural phenomena and the operation of devices and systems. The software is used for real as well as virtual aspects of computerised laboratory work. Software developed within the ComLab project can be downloaded from the Download section free of charge. In addition to the software developed within the ComLab project, some courses also employ software available on the web on a "freeware/shareware" basis. ComLab software will be continally upgraded during the project lifetimeand thereafter.

Currently, the following software packages are available:

• eProSim, a set of simulations for science and technology education
  
  
• eProLab, a suite of software utilities supporting the data acquisition system
  
  
• eProLib, programming libraries for data acquisition systems
  
  

This collection of courses focuses on specific science and technology topics. A characteristic of all of the courses is hands-on exercises, enabling specific target groups of teachers/students/pupils to engage in computer-based experiments by themselves. Interactive activities are an integral part of these multimedia-based courses.
