Question
what is difference between kernel and shell?
 Question Submitted By :: Unix-AllOther
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
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. 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.

Shell is a command interpreter
which acts as interface between user(UI) and Kernal
shell can execute no of commands with in single command in
logical order known as shell script

where as kernal is a group of programes writen in c lang to
interact with hardware directly

so user can interact with kernal though shell
only admin can interact with Kernal Directly in rare cases

Kernel is the heart of Unix which can only directly
interact with the set of device drivers.

Shell is the interface for user to give commands to unix
using the system calls what he wants to do with the
hardware devices.

kernel basically act as a interface to the hardware. it
gives commands in low level language to the hardware for
intereact it with our OS
while shell is a command line interpreter. it interprete
the command written in HLL to LLL and send it to the kernel
to perform it. So in this way we can say that kernel is
heart of the OS while shell is mind.

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.
