Introduction to the Linux Operating System
Before we learn Linux, let’s understand-
What is an Operating System?
Each time you switch on your computer, you see a screen where you can do different activities like write, browse the internet or watch a video. What is it that causes computer hardware work like that? How does the processor on your computer understand that you are asking it to run an mp3 file?
Well, it is the operating system or the kernel which does this work. A kernel is a program at the core of any operating system that takes care of primary functions, like making hardware communicate with software.
So, to operate at your computer, you need an Operating System(OS). You are using one as you read this on your computer. Now, you may have used favorite OS’s like Windows, Apple OS X, but here we will learn what Linux is and what benefits it offers over other OS choices.
What is Linux?
Linux is an operating system or a kernel. It’s issued under an open source license. Its functionality list is entirely like UNIX.
Who built Linux?
Linux is an operating system or a kernel which developed as a concept in the mind of young and bright Linus Torvalds when he was a computer science undergraduate. He used to operate on the UNIX OS (expensive software) and believed that it needed renovations.
However, when the creators of UNIX refused his ideas, he believed of launching an OS which will be open to changes, changes suggested by its users.
The solitary Kernel & the initial days
So Linus comes up with a Kernel named Linux in 1991. Though he would need applications like File Manager, Document Editors, Audio -Video applications to run on it. Something as you have a cone but no ice-cream on top
As time passed by, he co-operated with other programs in places like MIT and applications for Linux began to look. So about 1991, an effective Linux operating system with some applications was correctly launched, and this was the spring of one of the most popular and open-source OS opportunities available today.
The first versions of Linux were not so user-friendly as they were in use by computer programmers and Linus Torvalds never had it in mind to capitalize his product.
Linux’s popularity as other commercially oriented Operating System, Windows got popular although the open-source features of the Linux operating system made it further strong.
Linux gets its proper attention.
The main benefit of Linux was that programmers were able to use the Linux Kernel to produce their own custom operating systems. With time, a new series of user-friendly OS’s rained the computer world. Now, Linux is one of the most successful and extensively used Kernel, and it is the resolution of popular operating systems like Debian, Knoppix, Ubuntu, and Fedora. Nevertheless, the list does not finish here as there are thousands of OS’s based on Linux, which provide a variety of uses to the users.
Linux Kernel is regularly used in the blend of GNU project by Dr. Richard Stallman. All standard distributions of Linux are distributions of Linux/GNU
The advantages of using Linux
Linux now experiences popularity at its prime, and it’s popular among programmers as well as general computer users around the world.
Its main advantages are –
It gives a Free operating system. You do not have to shell numbers of bucks to get the OS like Windows!
- Being open-source, anyone with programming experience can transform it.
- The Linux operating systems presently allow millions of programs/applications to pick from, maximum of them free!
- Once you have Linux installed you no longer need an antivirus! Linux is an extremely secure system. More so, there is a global development association, continually studying at measures to increase its security. With every upgrade, the OS becomes more active and strong
- Linux is the OS of preference for Server environments due to its stability and reliability (Mega-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.
Linux for general Users
Users, who are fresh to Linux, usually avoid it by incorrectly thinking it as a technical and challenging OS to work but, to state the truth, in the last few years Linux operating systems have grown a lot more user-friendly than their equivalents like Windows, so trying them is the best way to know whether Linux suits you or not.
There are thousands of Linux based operating systems; largest of them contribute state-of-the-art security and applications, all of it for free!
Finally, this denotes what Linux is all about, and now we will proceed on to how to install Linux and which Distribution you should decide.
Am I asked to Learn Unix Then why Linux
UNIX described as the mother of operating systems which placed out the support to Linux. Unix is created mainly for mainframes and is in enterprises and universities. While Linux is fast growing a family name for computer users, developers, and server environment, you may have to spend for a Unix kernel while in Linux it is free.
But, the instructions used on both the operating systems are regularly the same. There is not enough difference between UNIX and Linux. Though others might seem different, at the core, they are mostly the same. Linux is a clone of UNIX. So learning one is the same as learning another.
