OSkernel
OSkernel is a conceptual operating system kernel used as a representative example in discussions of system design. It provides the essential services that run at the highest privilege level and interacts with hardware through a hardware abstraction layer.
Architecture: OSkernel follows a modular, loadable-kernel design that can be implemented as monolithic, microkernel, or hybrid,
Core components: Process management, memory management, I/O and device drivers, interrupt handling, interprocess communication, and a
Scheduling and memory: OSkernel implements preemptive multitasking, priority-based or fair scheduling, and context switching. Memory management
I/O and file systems: OSkernel provides a unified interface for block and character devices, a virtual file
Development and usage: OSkernel is described as open-source in many educational texts and is used to illustrate
