Microkernel

Kernel Architecture: Monolithic vs Microkernel Kernel design shapes how an operating system handles core tasks. The kernel sits at the center, managing hardware, memory, and communication between software and devices. Two common approaches are monolithic kernels and microkernels. Each has its strengths and trade-offs, and real systems often mix ideas. In a monolithic kernel, most services and device drivers run in a single, large kernel space. This means fast, direct calls inside a trusted environment. The upside is efficiency: system calls can be quick, and drivers can access data with little delay. The downside is safety: a bug in one driver can affect the whole system, and a big kernel is harder to validate and update. ...
