Kernel
The kernel is the hub or the heart of the Unix/Linuxoperating 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. It is the 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. When a user logs in, the login program checks the username and password, and then starts another program called the shell.
