Peking University , Beijing, P.R.China. This project is made for the course Operating System in fall 1998. It is a virtual OS and runs on the windows platform. Multiple users can login the system and one of them is super user.
Different user can share system resource simultaneously.
All the processes compete for the system resources and we use round-robin algorithm to distribute CPU time and solve deadlock. While the process ends, it will recycle the memory back. Multiple users can open same file simultaneously. In this project, first I began with drawing point and changing different colors with assembly language. Lines, circles, polygons are all with our own algorithms.
