Why is it used widely and what is its main feature?

There are plenty of features in Linux but the main key feature of Linux is its modularity, which allows users to customize and configure the operating system to suit their specific needs. This particular flexibility of Linux makes this as a popular choice for a wide range of applications, including web servers, database servers, scientific computing, and even desktop computing.
Overall, Linux is a powerful, flexible, and secure OS that offers a wide range of features and benefits. Its open-source nature and large community of developers also ensure that it will continue to evolve and improve for many years to come.

Linux Architecture:

Let us understand Linux Architecture by a simple Example:

Application --> Any App which will be appearing on Screen

EX: Camera App

Shell --> Shell is the interpreter between the Application and the Kernel.

(Or) Shell is interpreter which is used to access kernel.

Kernel --> This is the Main Interface between Software and Hardware.

Hardware --> Physical component of a computer or other electronic system.

EX: Camera Module

Scene here:

When we tap on Camera Icon (Application) this will trigger Shell and it then tells kernel to switch on Camera Module (Hardware).
