Which of the following is a characteristic of a monolithic kernel?
A. All OS services run in kernel mode with high performance
B. Only the core services run in kernel mode, others in user mode
C. It is easier to extend
D. It is more stable than microkernel
Answer: Option A
Solution (By JKSSB Mock Tests)
Monolithic kernel includes all system services (file system, drivers, memory management) in kernel space, which can improve performance but reduce stability.
