External connections are based on fiber-optics. For processor intensive applications there is a mini supercomputer Convex available. It is not possible to say how many workstations and PC's are there. There are two VAX 4000-200 for the university information system and for the library services. For communication purposes we have a special communication system, consisting of dedicated computers VAX 4000-200, SUN SparcClassics and Cisco routers.
