Basically, Linux is a kernel, not the OS. The Linux kernel is monolithic. Monolithic kernels control the CPU, memory, Inter-Process Communication, device drivers, file system management, and system server calls.
Is Linux the kernel or OS?
Linux is a kernel, not the OS:- The program in the system that allocates the machine’s resources to the other programs that you run is known as the kernel. The kernel is an essential part of an operating system, but useless by itself, it can only function in the context of a complete operating system.
