when a process or anything makes a system call ,it goes in kernel(operating system).
a corn kernel
Yes, they are the interface to kernel functionality. To quote wikipedia: a system call is how a program requests a service from an operating system's kernel that it does not normally have permission to run
Shell Programs
The program that surrounds the kernel of the operating system is called the "user space" or "user mode." It includes all the user-level applications and services that interact with the kernel, which operates in "kernel space" or "kernel mode." This separation helps ensure system stability and security by restricting user applications from directly accessing critical system resources managed by the kernel.

The tip of a writer's quill is call the 'nib.'
A sign holder.
The Linux kernel will automatically call "init." init will in turn launch any other processes. You can add a process in by creating a script for it in the appropriate run level.
The virtual kernel is a kernel that can be used in unbuntu guest. It is a very lean kernel, this helps in reducing overhead. It installs the server kernel via a new name.
The Kernel
Mac OS X is based on the XNU kernel, a microkernel Mach kernel with a BSD userland, which makes Mac OS X's kernel a hybrid-kernel.
