An Introduction to Linux Operating System

Linux Operating System

Before we learn about Operating System, we should understand

What is an operating system?

Each time you turn on your computer, a screen is displayed on which you can perform various activities, such as: Writing, surfing the internet or watching a video.  What causes the computer hardware to work this way?   How does the processor on your computer know you’re asking for it?   MP3 file   perform   ?

Well, it’s the operating system or kernel that does that.   A kernel is a program at the heart of an operating system that does basic things, such as hardware-software communication.

So, to work on your computer, you need one   operating system (OS).   In fact, you use one while you read it on your computer.   You may have used popular operating systems like Windows or Apple OS X, but here’s what Linux is about and what it does over other operating systems.

What is Linux?

Linux is an operating system or a kernel.   It is distributed under an open source license.  The list of functions is similar to that of UNIX.

Who created Linux?

Linux is an operating system or kernel that has germinated as an idea in the minds of Jung and Hell Linus Torvalds, when he was a computer science student.  He worked at the UNIX OS (proprietary software) and thought that it needed improvements.

However, when his suggestions were rejected by the designers of UNIX, he considered launching an operating system that will be available shortly    susceptible to changes, modifications proposed by the users .

The Lone Kernel & the early days

So Linus designed a kernel named Linux in 1991. Although he has programs like File Manager, Document Editors,  audio   Video programs   would need to get on it   to run.   Something like you have a cone, but no ice on top.

Over time, he worked with others Programmers in places like MIT and applications for Linux appeared.  So in 1991, a working Linux operating system with some applications was officially launched, and this was the beginning of one of The most popular and up-to-date open source operating system options   ,

The earlier versions of Linux were not so user-friendly, as they were used by computer programmers and Linus Torvalds never intended to advertise his product.

This definitely diminished the popularity of Linux as other commercially-oriented Windows operating systems became famous. However, the open source aspect of the Linux operating system made it more robust.

Linux Gets its Due Attention

The main advantage of Linux was that programmers could use the Linux kernel to design their own custom operating systems.   Over time, new user-friendly operating systems stormed the computer world.   Now, Linux is one of the most popular and widely used kernels  and it’s the backbone of popular operating systems like   DebianKnoppix, Ubuntu and Fedora.   Nevertheless, the list does not end here, as there are thousands of Linux-based operating systems that offer users a variety of features.

Linux kernel is usually used in combination of     GNU     Project from   Dr.   Richard Stallman.   All  modern   Linux distributions are actually Linux / GNU distributions

The advantages of Linux

Linux is now enjoying great popularity and is known to programmers as well as regular computer users around the world.   The main advantages are:

  • It offers one free operating system,   You do not have to shell out hundreds of dollars to get an operating system like Windows!
  • As an open source, anyone with programming skills can make changes.
  • The Linux operating systems now offer millions of programs / applications to choose from  most of them for free!
  • Once you have Linux installed, you no longer need an antivirus!   Linux is a very secure system.   In addition, there is a global developer community constantly looking for ways to improve their security.   With each upgrade, the operating system becomes safer and more robust
  • Linux is the operating system of choice 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 for years without a restart without a break.

Is Linux for me?

Users who do not yet know Linux typically avoid it by mistaking it for a difficult and technically-manageable operating system. In recent years, however, Linux operating systems have become much more user-friendly than their counterparts Windows. If you try them, the best way to tell if Linux suits you or not.

There are thousands of Linux-based operating systems; most of them offer State-of-the-art security and applications everything is free!

That’s what Linux is all about, and now we’ll look at how Linux is installed and which distribution you should choose.

I am asked to learn Unix?   Why Linux then?

UNIX is called the mother of the operating systems that laid the foundation for Linux.   Unix   was mainly developed for mainframes and is used in companies and universities.  While Linux is becoming increasingly popular for computer users, developers and server environments.   You may have to go for one   Unix   kernel   pay,  while under Linux it is free.

But the the commands used on both operating systems are usually the same.  There is not much difference between UNIX and Linux   they may seem different in essence, they are essentially the same.   Since Linux is a clone of UNIX,   Learning one is the same as learning another.
