Why Linux kernel is monolithic?

One of the major advantages of having a monolithic kernel is that it provides CPU scheduling, memory management, file management, and other operating system functions through system calls. The other one is that it is a single large process running entirely in a single address space. It is a single static binary file.

What is the Linux kernel and how does it work?

He is responsible for ensuring that everything works well, that it is done safely, and that there are no errors. If a process crashes in user space, Linux continues to function . And you can even try to recover the system by having control over the PC.
