What is the difference between a user process and a kernel?
Kernel: The nucleus of the operating system in contact with the CPU. User processes: All running processes that the kernel manages. The kernel makes communication between processes and servers possible, also known as Inter-Process Communication (IPC). There are two modes for the code in a system: kernel mode and user mode.
What are the components of an operating system?
1 Hardware: The foundation of the system, made up of RAM, the processor and input and output devices. The CPU carries out reading and writing operations and calculations for the memory. 2 Kernel: The nucleus of the operating system in contact with the CPU. 3 User processes: All running processes that the kernel manages.
What is A multikernel kernel?
The kernel is not the core of a processor, it’s the core of the operating system. A kernel is also not an API or framework. Multikernel operating systems can use various cores of a multicore processor like a network of independent CPUs. How does that work?
