Operating System Architecture Simulator

OS ki architecture 6 layers par mushtamil hoti hai. Sabse upar User, phir Application Program, phir Shell / System Utilities. Inke neeche System Call Interface hai jo User Mode aur Kernel Mode ke darmiyan boundary (darwaza) ka kaam karta hai. Uske neeche Kernel (Process, Memory, File aur Device Management) aur sabse neeche asal Hardware (CPU, RAM, Disk, I/O) hota hai. Application seedha hardware tak nahi ja sakti, har request ko System Call Interface se guzar kar Kernel ke zariye jana parta hai.
