Kernel Vs. Shell: Know the Difference Between Kernel and Shell
Both of these are used in a computer system for establishing communication and operating the system. But there is a fundamental difference between shell and kernel. A shell is basically an interface present between the kernel and the user. It allows all of its users to establish communication with the kernel. A kernel is the very core of a typical OS. It functions to control all the tasks that come with a system. Let us know a bit more about each of these individually.
What is a Shell?
It refers to a special user program or an environment that provides a user with an interface for using the services of the operating system. A shell executes various programs on the basis of the input that a user provides.
What is a Kernel?
A kernel is basically the core and the heart of an OS (Operating system). It functions to manage the operations of the hardware and the computer. A kernel basically acts as a bridge between any user and the various resources offered by a system by accessing the various resources of a computer, such as the I/O devices, CPU, and various other resources.
Difference Between Shell and Kernel
Let us talk about the differences present between Shell and Kernel.
|Basics||A shell is basically an interface present between the kernel and the user.||A kernel is the very core of a typical OS.|
|Meaning||A shell is a CLI (command-line interpreter).||A kernel is a type of low-level program that has its interfacing with the hardware on top of which all the applications run (disks, RAM, CPU, etc.).|
|Uses and Purpose||A shell allows all of its users to establish communication with the kernel.||A kernel functions to control all the tasks that come with a system.|
|Types||Korn Shell, C Shell, Bourne Shell, etc., are types of shells.||Hybrid kernel, Micro-kernel, Monolithic kernel, etc., are types of kernels.|
|Functions||We can use shell commands such as mkdir, ls, and many more for requesting the completion of the specific operation to the operating system (OS).||A kernel carries out the commands on a group of various files by specifying the pattern that can match.|
|Management||A shell performs memory management.||A kernel performs process management.|
|Layer of OS||The shell forms the outer layer of the operating system.||The kernel forms the inner layer of the operating system.|
|Machine-Understandability||A shell interacts with all of its users and then interprets into a language that is understandable by the machine.||A kernel interacts with the hardware directly because it accepts the machine-understandable language from the available shell.|
