ASTER is a program which enables several users to work with one computer as independently as if each of them had their own PC. It is a software solution and does not use thin clients and terminal stations. To set up each workstation, one connects another monitor, another keyboard and an extra mouse to the available computer. After installation and start-up, it will present a separate desktop on each monitor and users will be able to work with the computer as independently as if each of them had their own PC.
