Basics of linux operating system

Now a days linux is getting popularity among many corporate sector and mobiles over microsoft because of its tight security system and multi-user and multi-tasking interface. Here in this article I am going to describe completely about Linux world step by step:

linux an operating system which is not only a free operating system but lots of more…

WHAT IS LINUX ?

Linux is a kernel in short; it is a free operating system which is used
by lots of users all over the world. It is a multi-tasking and multi-user
operating system.

Now lets us proceed step by step to explore and to reach to the

A BRIEF HISTORY OF LINUX-

Linus Torvalds introduces Linux in 1991. Linux is developed keeping UNIX as reference
model. We can consider Linux as another UNIX version. Mr. Linus has made the source code of the
Linux kernel explores among the world of education and to develop and change over the internet.
Linux is an open development model. It accepts modification to the kernel core. The core of the Linux is
kernel which controls the resources of the computer and allots this resource to the users and for
different tasks. In simple words kernel allows the user to interact with the hardware.as we cannot
directly access kernel, rather we need an interface to connect to kernel called “SHELL”…

UNIX SHELL

BOURNE SHELL: – original UNIX shell written by Steven Bourne at AT & T laboratory. This is the default
shell for Linux.

C SHELL: – written by bill joy at UC Berkeley.

KORN SHELL (K SHELL) :- written by DAVID KORN at AT & T lab.

X- WINDOWS SYSTEM

The x windows system for x11 is the foundation for GUI (Graphical User Interface) on Linux. The x
server works with graphics hardware (VGA) and the applications requires graphic display is an x client.
Linux provides two desktop environments.

1:- GNOME

2:-KDE

By default Linux has configured 6 virtual console and 1 x console. We can move to any virtual console
by typing ctrl + alt +Fx, where x stands for 1 to 6 and F1 is the x console.

BASIC INFORMATION AND STRUCTURE OF AN OPERATING SYSTEM (OS) :

Nowadays in this computerized world, nothing will be done in a computer without an operating system…… so its important that one must understand this operating system as clear as possible…

so here I am trying to let you guys understand the working of an operating system, very clearly…

Whenever you guys turn on your PC or laptop  it’s great to think that you’re the controller. The computer mouse which you can move everywhere on the screen, play music surf internet and control your settings. Although it’s very cool to feel like a controller in front of your computer or laptop, there’s a lot going on inside of your PC, and the real hero behind the curtain handling all the necessary tasks is the OS or Operating System. The operating system (OS) is the foremost thing loaded onto the computer …. without this your computer is useless.

So what is OS and how this stuff works???

An operating system (OS) is basically a collection of software that manages the computer hardware resources & provides common services for programs of computer. The OS is a vital component of the system software in a computer. All the Application programs usually require an operating system to function as it link the user with the hardware.

Some common OS- 

The  popular modern operating systems are Android, iOS, BSD,  Mac OS X, QNX, Microsoft Windows,Linux,Windows Phone & IBM z/OS. 

Working of OS:-

In simple language an operating system is a bridge that connects user with the hardware and it operates the proper functionality of the system, as it is the road where all the applications performs……

The main purpose of an operating system is to control and well organise the software and hardware so that the device it lives in behaves in a flexible but in a predictable way.The user remains behind the curtain which works out of the boundary.

OS understands only English or sometimes any high level language…

Then the application part, which is software, helps to run all the programs and performs several tasks on computer…

The outermost part is the shell which interacts with the user commands, receiving from the application part…

Then the role is played by the essential layer of an operating system “KERNEL” it outputs the basic services or functions to all other parts of operating system on behalf of user commands, queries, or other applications…

 The innermost part is the hardware which understands only the 0, 1 (binary) language…

Now it is totally clear about the basic information about the structure and working of an operating system…..
