controlling hardware access and managing application s
i finnally freackin found it, real mode(16 bit) allows access to all hardware resources, where protected mode(32 bit) controls how the application accesses the hardware. In real-mode, an application has complete access to all hardware resources. This "open door" policy can create problems when applications make conflicting commands to the hardware. In protected mode and long mode, the OS controls how an application can access hardware.page 53 in CompTIA A+ Guide to Managing & Maintaining Your PC, Sixth Edition by Jean Andrews

Application Pools
HAL (Hardware Abstraction Layer). Limiting access to hardware mainly to the HAL increases OS integrity because more control is possible. With this isolation, an application cannot cause a system to hang by making illegal demands on hardware. (Source: CompTIA A+ Guide to Software Managing, Maintaining, and Troubleshooting.

DOS (Disk Operating System) consists of three main components: the BIOS (Basic Input/Output System) for low-level hardware control, the kernel for managing memory and processes, and the command interpreter (COMMAND.COM) for facilitating user interaction with the system.
