What is kernel with diagram?

What are the main components of Unix architecture?
Unix is made up of 3 main parts: the kernel, the shell, and user commands and applications. The kernel and shell are the heart and soul of the operating system. The kernel ingests user input via the shell and accesses the hardware to perform things like memory allocation and file storage.
What are main features of Unix?
The UNIX operating system supports the following features and capabilities:
- Multitasking and multiuser.
- Programming interface.
- Use of files as abstractions of devices and other objects.
- Built-in networking (TCP/IP is standard)
- Persistent system service processes called “daemons” and managed by init or inet.

What is the difference between Linux and Unix?
Linux is a Unix clone,behaves like Unix but doesn’t contain its code. Unix contain a completely different coding developed by AT&T Labs. Linux is just the kernel. Unix is a complete package of Operating system.
What is difference between Shell and kernel?
Kernel is the heart and core of an Operating System that manages operations of computer and hardware.
…
Difference between Shell and Kernel :
| S.No. | Shell | Kernel |
|---|---|---|
| 1. | Shell allows the users to communicate with the kernel. | Kernel controls all the tasks of the system. |
| 2. | It is the interface between kernel and user. | It is the core of the operating system. |
