The kernel and the shell are two different parts of the OS or operating system. The shell interprets the commands from input. The kernel houses the heart of the OS like the command files and execute applications.

Kernel electrons are the electrons that orbit the nucleus of atom and are NOT considered to be part of the valence shell.
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.
The shell is made up of several subsystems that all operate in user mode. The kernel, or core, of the OS is responsible for interacting with hardware. It has more power to communicate with hardware devices than the shell has, and operates in kernel mode.
Operating System have a major component called KERNEL that is designed to interact with hardware .Kernel acts as an interface between OS Shell & Hardware.
Not only DOS, in any Operating System, there are mainly two parts:1. Kernel: The core of OS..2. Shell: Interface between Kernel and User..
kernel is everything in unix os
A shell program is the interface between the user (environment) and the operating system (kernel). It allows users to specify commands and requests the operating system to execute them.
The OS makes calls to the system kernel (although sometimes the kernel is bundled with the OS). Applications make their calls to the OS, which then makes calls to the kernel.
Mac OS X is built on the XNU (X is Not Unix) kernel which is a hybrid combining elements of the Mach kernel and FreeBSD.
Mac OS X uses a Mach kernel and FreeBSD utilities at it's core.
