Kernel Architecture: A Global Perspective Kernel architecture shapes how a computer uses memory, schedules work, and talks to devices. It sets limits on speed, safety, and stability. Around the world, teams choose different designs to fit hardware, goals, and open standards. This overview looks at the main ideas and the global mix of systems. Models in brief Monolithic kernels place most services inside a single core, which can be fast but harder to secure. Microkernels keep the core small and push many services into user space, which can improve fault isolation. Hybrid or layered designs mix ideas to balance performance and safety. A global landscape ...
