A shell is any of various objects resembling such a covering, as in shape or in being more or less concave or hollow and a kernel is the softer, usually edible part contained in the shell of a nut or the stone of a fruit.
The shell is the interface between users and operationg systems..Kernel
Operating System have a major component called KERNEL that is designed to interact with hardware .Kernel acts as an interface between OS Shell & Hardware.
difference between layered and kernel base approach in OS structure
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..
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.
A kernel is the heart of the operating system and acts as a middle ground between hardware and software. Some (if not all) device drivers are kernel-level drivers as kernelmodules. A shell is a command terminal that allows the user to interact with the user.
Shell is the bridge between Kernel and User.
The shell is the interface between users and operationg systems..Kernel
The kernel The kernel is the hub of the operating system: it allocates time and memory to programs and handles the filestore and communications in response to system calls. The shell The shell acts as an interface between the user and the kernel. When a user logs in, the login program checks the username and password, and then starts another program called the shell.
A command is something that's built-in to the kernel, where as the utility is something that runs on top of the kernel. Example of utilities are: fdisk, copy, edit, etc.
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.
shell and orbit are same

Layers of UNIX Operation System along with an example to illustrate the interaction between shell and Kernel.The UNIX operating system is made up of three parts: the kernel, the shell and the programs.The kernelThe kernel of UNIX is the hub of the operating system: it allocates time and memory to programs and handles the filestore and communications in response to system calls.The shellThe shell acts as an interface between the user and the kernel. The shell is a command line interpreter (CLI). It interprets the commands the user types in and arranges for them to be carried out. The commands are themselves programs: when they terminate, the shell gives the user another prompt ($ on our systems).The programsA program is refereed to as a process while the kernel is running it. The Kernel can run the same shell program(or any other program) simultaneously for many users on a Unix System, and each running copy of the program is a separate process. The Shell is also a program that the UNIX Kernel runs for the user.As an illustration of the way that the shell and the kernel work together, suppose a user types rm myfile(which has the effect of removing the file myfile). The shell searches the filestore for the file containing the program rm, and then requests the kernel, through system calls, to execute the program rm on myfile. When the process rm myfile has finished running, the shell then returns the UNIX prompt $ to the user, indicating that it is waiting for further commands.- Submitted by SRKStudent of NIITContact No. : +91-9534330837Email: shoaibrazakhan@gmail.com
