Introduction to the Linux Operating System.

This is an first step in the long tutorial "Linux for Beginners" where we will understand what is an  Linux operating system and how it came to birth.

Before moving anywhere ahead let us first understand what is an Operating System.

Operating System (OS) is an interface between a computer user and computer hardware.

It’s an software which performs all the basic tasks like

File management,

Memory management,

Process management,

Handling input and output devices

and controlling peripheral devices such as

Disk drives

Printers

So every time we switch on our computer, we can see a screen where we can perform different activities like :

Writing, reading, browsing or even watching a YouTube video.

What is it that makes the hardware work like that?

How does the hardware on your computer know that you are asking it to run a video ?

The answer is the operating system

or

the kernel which does this work.

A kernel is the program at the heart of any operating system that takes care of every fundamental communication between the computer hardware and the software.

So now it’s clear that we need an OS to work on your computer.

As a live example you are using one as you viewings this on your computer.

There are also other popular OS's like :

Windows, Apple OS X or AIX

but as a part of our learning course we will learn Linux over here.

How was Linux created ? & who created it  ?

In 1991 Linus Torvalds purchased a new IBM compatible computer

where he was using MS DOS on it, but was not happy with it and thought of using Unix.

After using Unix Torvalds thought and came up with some changes in the kernel, but was put down by the Unix community.

This was the opening of Linux, it was an start of new open source kernel named Linux.

Later many other played their part in the history and made some cool OS over Linux kernel.

What are the Advantages of Linux ?

The main advantage of Linux was as follows: 

Programmers are able to use the Linux Kernel

 in order to design their own custom operating systems.

It is an free operating system.

You do not have to spend hundreds of dollars to get the OS like Windows!

We can get millions of programs

most of them free!

Once you have Linux installed

you no longer need an antivirus!

Linux is a highly secure system

 So who use it?

Large companies like Amazon, Facebook ,and Google use Linux for their Servers.

A Linux based server could run non-stop without a reboot for years on end.

Thank you friends for reading the blog post on Introduction to Linux.

Now it would have been clear to you guys what is an Linux OS, lets meet in the next post where we will discuss about the Distributions.
