Definition - What does Monolithic Kernel mean? A monolithic kernel is an operating system software framework that holds all privileges to access input/output (I/O) devices, memory, hardware interrupts and the CPU stack.
5) In Monolithic kernels, the device drivers reside in the kernel space while in the Microkernel the device drivers reside in the user space. 6) Since the device driver resides in the kernel space, it makes monolithic kernel less secure than microkernel, and failure in the driver may lead to crash. Microkernels are more secure than the monolithic kernel, hence used in some military devices.
