Answer / ravichand

user -> shell -> kernel -> hardware

Shell is a command interpreter. It is an interface between user and kernel.When you type any command at your terminal the shell interprets(takes) command
and calls the program what you want.The shell uses standard syntax for all commands. C shell,Bourne shell and Korn shell are most famous shells in Unix 
environment.

Kernel is heart of operating system.This sits on top of Hardware and it interacts with the hardware. This is the core of the Operating system and acts as an 
interface between the user activities and the hardware. It provides the base functionality of the OS. The major functionality of the kernel includes process 
management, memory management,thread management, scheduling, I/O management and power management.

A shell is a command interpreter, i.e. the program that either process the command you enter in your terminal emulator (interactive mode) or process shell scripts (text files containing commands) (batch mode). In early Unix times, it used to be the unique way for users to interact with their machines. Nowadays, graphical environments are replacing the shell for most casual users.

A kernel is a low level program interfacing with the hardware (CPU, RAM, disks, network, ...) on top of which applications are running. It is the lowest level program running on computers although with virtualization you can have multiple kernels running on top of virtual machines which themselves run on top of another operating system.

Answer / chetna swarnkar

kernel is a core operating system.it provides set of service
that can be used by the programmers.and the major function
of kernel are to manage computer memory to control access to
the computer, to maintain the file system, to handle
interrupts to handle errors,to perform inputs and output
service (which allows computers to interacts with
terminals,storage device and printers)and to allocates the
resources of the computers(such as cpu or input/output
device among users)
while the shell reads your commands and interpreters them as
requested to execute a program or programs which it then
arranges to have carried out, as the shell plays their
role.so it is called a command interpreters, the shell is a
programming language. as the programming language , it
permits you to control how and when commands are carried out.

Post Kernel And Shell clarifications??
Hey Gang,

What is the main difference between the Kernel and the Shell
in a Windows environment. Is the kernel the main part of my
Windows 98SE Op.Sys which would include the MSDOS.SYS,
IO.SYS and COMMAND.COM files or is it something else??

What is the shell? Is the shell simply the command prompt I
see when I start up DOS, or is it the desktop that I see
when I start up Win98SE??

One last question.... what is kernell32.dll?? I know that
the 32 part refers to 32 bits but what does that actually mean??

Thanks every1 once again :-)

Shell is a user program or it's environment provided for
user interaction. Shell is an command language interpreter
that executes commands read from the standard input device
(keyboard) or from a file.

Shell is not part of system kernel, but uses the system
kernel to execute programs, create files etc.

Answer / harsh rajpal

And kernel starts with k.
