ā¢ What is Linux ?
Linux is a free and open-source software operating system , which is based on UNIX, is well-known for its strong security, reliability, and high performance. It is very flexible, receives regular software updates, and offers both easy-to-use graphical interfaces and powerful command-line tools. Linux is also great for networking and is easy to install, Linux don't have CLI(command line interface).
There are many different versions of Linux, called distributions or "distros," each with its own unique features and capabilities. Some popular distributions include Ubuntu, CentOS, Red Hat, and Debian. Each of these distros is designed to meet different needs and preferences, making it easier for users to find one that suits them best.
ā¢ History Of Linux
The history of Linux started in 1991 when Linus Torvalds, a student from Finland, wanted to create a free and open operating system. He was inspired by another system called MINIX and wanted to make something better. On September 17, 1991, he released the first version of the Linux kernel
ā¢ Linux File System Hierarchy
In linux everthing is represented as a file or folder(directory) , the files are stored in a directory and every directory contains files with a tree structure
linux uses single rooted , inverted tree-like structure , root directory represent with /(forward slash) it is a top level directory in linux
ā¢ What is linux architecture diagram ?
A Linux architecture diagram shows how the different parts of the Linux operating system work together. Here are the main components:
Hardware: The physical parts of the computer, like the CPU, memory, and storage.
Kernel: The core of the operating system that manages hardware and system resources.
System Libraries: Special programs that help applications interact with the kernel.
System Utilities: Basic tools for managing the system, like file management and system monitoring.
User Applications: Programs that users interact with, such as web browsers and text editors.
Shell: The command-line interface where users can type commands to interact with the system.
This structure helps the operating system run smoothly and efficiently.
Note :- Remember this architecture using ASK word (A->Application , s->shell , k->kernal

ā¢ Summary
introduces Linux, its history, and its basic components in a way that's easy for beginners to understand. It starts by explaining that Linux is a free and open-source operating system known for its security, reliability, and speed. The post then covers the history of Linux, noting that it was created by Linus Torvalds in 1991. It also explains the Linux file system, which organizes files and directories in a tree-like structure. Additionally, the blog includes a diagram of Linux architecture, breaking down its main parts: hardware, kernel, system libraries, system utilities, user applications, and the shell. The post ends with links to useful Linux commands for further learning.
