With advances in technology, in research institutions or academics there have many labs. Normally, one of these labs have 30 or more sets of computer. Based on the characteristic of the labs, these computers would have a distinct operating environment. Maintain the normal operations of these computers are quite complicated. In this thesis, we studied several software and/or hardware packages that have been used in computer classroom. These packages include based on no hard disk and/or hard disk management system. The experimental results demonstrate that how to choose the most appropriate management software/hardware in computer classroom.
