operating systems

The operating system is a layer of services of the whole computer system, which manages the hardware resources, allows the user to drive the system, and makes the boundary between hardware and software transparent. The operating system consists of four subsystems: process management, memory management, input/output management, and file management. The aims of the memory management subsystem are to share the memory space between several concurrent processes; protect each process from each other; allow sharing of memory space, where desired; and make the addressing of memory space as transparent as possible for the programmer and end user. The aim of this project is to develop a software package to demonstrate and animate the core working mechanisms of memory management subsystem of operating systems in either C++ or Java.
