Hi, Guys. This is mine knowledge sharing sections.

In here, you can learn and read about *nix operating systems.

This systems are for programmer and hackers ! .

Thats why all of you should learn this OS.

Lets start now !

That’s the Operating System folder structure of *nix units. Important folders in the OS.

Lets check it out.

Linux Operation System

/ – File System

/boot – Bootload and Kernel

/bin – Essential Command binaries ( ls, cp, mv, cat )

/sbin – Essential System Binaries ( fsck, init, route )

/dev – devices

/etc – Application Configuration

/var – Variables files such as logs and tempory emails

/home – User Directories

/root – Root Home Directory

/usr – Read Only User Data

/tmp – tempory directory

/opt – Optional Software Package

/media – Mount Area

/mnt – Mount Area

In here, lets start about with operating system’s software and harware life cycle.

An operating system

An operating system is software that manages all of the hardware resources associated with your desktop or laptop. To put it simply – the operating system manages the communication between your software and your hardware. Without the operating system (often referred to as the “OS”), the software wouldn’t function.

The Bootloader

The software that manages the boot process of your computer. For most users, this will simply be a splash screen that pops up and eventually goes away to boot into the operating system.

The kernel

This is the one piece of the whole that is actually called “Linux”. The kernel is the core of the system and manages the CPU, memory, and peripheral devices. The kernel is the “lowest” level of the OS.

Daemons

These are background services (printing, sound, scheduling, etc) that either start up during boot, or after you log into the desktop.

The Shell

You’ve probably heard mention of the Linux command line. This is the shell – a command process that allows you to control the computer via commands typed into a text interface. This is what, at one time, scared people away from Linux the most (assuming they had to learn a seemingly archaic command line structure to make Linux work). This is no longer the case. With modern desktop Linux, there is no need to ever touch the command line.

Desktop Environment

This is the piece of the puzzle that the users actually interact with. There are many desktop environments to choose from (Unity, GNOME, Cinnamon, Enlightenment, KDE, XFCE, etc). Each desktop environment includes built-in applications (such as file managers, configuration tools, web browsers, games, etc).

Applications

Desktop environments do not offer the full array of apps. Just like Windows and Mac, Linux offers thousands upon thousands of high-quality software titles that can be easily found and installed. Most modern Linux distributions (more on this in a moment) include App Store – like tools that centralize and simplify application installation.

For example: Ubuntu Linux has the Ubuntu Software Center, which allows you to quickly search among the thousands of apps and install them from one centralized location.

Thats all. See you in next articles.
