what is difference between kernel and shell?

Answer Posted / ganesan.k

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.
