Which area contains the core operating system components and device drivers that interact directly with hardware?

• A. System Space
• B. Hardware Space
• C. Kernel Space
• D. User Space

Answer: (C)

The area where the core operating system components and device drivers that interact directly with hardware reside is kernel space. The kernel operates in a privileged mode and is responsible for essential functions like scheduling, memory management, and input/output. Device drivers need direct, low-level access to hardware resources to issue commands, read status, and handle interrupts, which is why they live in the kernel. In contrast, user-space programs run with restricted privileges and access hardware only through controlled interfaces provided by the kernel, ensuring protection and stability. The terms system space or hardware space aren’t standard architectural terms in most OS models, and user space is for applications, not the core hardware-interacting components.
