what is difference between kernel and shell?

Answer Posted / 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.
