Difference between a Kernel and Shell
A shell is a command interpreted, way to communicate with the operating system and kernel using the command line.
Consider what would happen if we have only kernel and no shell ?. We would have a device with OS but there is no method to use it. We need to have an interface between OS and humans. That’s shell’s purpose
A kernel is a low-level program interfacing with the hardware in privileged mode. It is an essential part of the system. Any requests from the shell is processed by the kernel.
It is impossible to have a shell without a kernel. Without a kernel, we can not execute commands.
A kernel is the lowest level program running on computers. The kernel does task scheduling, handles filesystems, I/O handling, memory management.
