Inside Linux: Unveiling the Magic of the Open-Source Universe
Introduction to Linux
๐ง Linux, developed by Linus Torvalds in September 1991, is an open-source operating system.
๐ช Linux is known for its stability, security, and flexibility.
๐จ It can be adapted to numerous purposes and hardware platforms.
โ๏ธ Linux powers many devices, including servers, desktop computers, smartphones, and embedded systems.
๐งLinux belongs to the Unix-like family of operating systems.
๐ฅ The Linux community is a global network of developers who contribute to its growth and improvement.

Linux architecture:
Hardware Layer: The lowest layer of Linux architecture consists of physical hardware components like CPU, RAM, storage devices, and peripherals
Kernel Layer: The kernel is the core component that interacts directly with the hardware, managing resources, handling processes, and providing essential services to other layers.
Shell: The shell provides a command-line interface for users to interact with the system.
Application Layer: At the top layer, users interact with applications like web browsers, text editors, and multimedia players to perform specific tasks.
Each layer builds upon the lower one, providing a modular and organized structure that makes Linux powerful and versatile.
