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.
When a process makes requests of the kernel, the request is called a system call. Various kernel designs differ in how they manage system calls and resources. For example, a monolithic kernel executes all the operating system instructions in the same address space in order to improve the performance of the system.he critical code of the kernel is usually loaded into a protected area of memory, which prevents it from being overwritten by other, less frequently used parts of the operating system or by applications.
