It decides which program gets to use the processor and for how long, enabling multitasking.
It provides a uniform interface for software to interact with diverse hardware (like printers or GPUs) without needing to know the low-level specifics of each device. kernel os
Unlike monolithic kernels that bundle drivers and file systems, Kernel OS implements a strict microkernel architecture—only the absolute essentials run in privileged mode (Ring 0). Everything else, from the VFS to the scheduler policy, lives in user space. It decides which program gets to use the
: A middle ground that combines the speed of monolithic designs with some of the modular safety of microkernels. Windows NT (the base for Windows 10/11) is a well-known hybrid. "Kernel OS" vs. "Operating System" kernel os
