Linux is an operating system that evolved from the kernel created by Linus Torvalds, a student at the University of Helsinki when Linus created the kernel. This is the usual sense of Linux that is well known to everyone. But for political and practical reasons, it needs to be explained in depth. Calling Linux an operating system means that it is an optional operating system for other operating systems, such as Windows, Mac OS, MS-DOS, Solaris, and so on. Linux is not a word processor or a combination of office suites. Linux is a computer/server hardware and an interface for programs that run on it.

Introduction to Linux History
when Linus was studying at the University of Helsinki, he was using a UNIX version of the operating system called "Minix". Linus and other users submitted modification and improvement requests to Minix's creator, Andrew Tanenbaum, but Andrew thought none of this was necessary. From then on, Linus decided to write his own operating system, which could take into account the comments and recommendations made by the user for system improvement.
Free software Pre-linux
seeking user's comments and suggestions to improve computer programs This philosophy is not new. Richard Stallman, who works at MIT (Massachusetts Institute of Technology,mit), pioneered and used this method to program computers in the 1970s. He is a pioneer of the concept of "free software" and points out that "free" is "freedom" rather than a no-charge. He found it difficult to continue working in an environment that conflicted with his concept of "free software". He left MIT in 1984 and created the GNU. The GNU goal is to produce software that can be freely used, distributed, and modified. After 6 years, Linux has a similar goal: to produce an operating system that takes user feedback into account.
Kernel
We must point out that the focus of each operating system is its kernel. Without going into the details, the kernel tells the chip that controls your computer to do what you want your program to do. For example, if you go to your favorite Italian restaurant and order spaghetti spaghetti, this dish is like your operating system. There are a lot of things to do, like noodles, tomatoes, meatballs and cheese. The kernel is like noodles, and this dish does not exist. You can also find some bread to make sandwiches. Just a plate of noodles is going to be a pretty disgusting one. Without the kernel, the operating system does not exist. Without a program, the kernel is useless.
1991, a year of life and death
in the 1991, the ideal environment for creating Linux existed. Basically, Linus Torvalds has the kernel but without his own application, Richard Stallman and GNU have applications but no kernel to work with. Take a look at these two men's words about this:

Linux Join
 By the end of 1991, Linus Torvalds bundled his kernel with some GNU programs, which would work well enough to show others what he had done. That's what he did. The first person to see Linux knows Linus is ready to do something. At the same time, he needs more people's help. Back in 1991, this is what Linus said:

 people all over the world are ready to help him. At first, only a little computer programming knowledge can do anything for earlier versions of Linux. Those people began to offer help. The version number of Linux is getting bigger and larger. People started writing special programs that run under Linux systems. Developers are starting to write different drivers, such as different video cards, sound cards, and other internal and external peripherals. Still, the vast majority of the first parts of Linux throughout the the 1990s were Linux and did not go out of the ' Gubu ' phase. Giru is a phase in which everyone has special expertise in specific areas. That is to say, in those days you have to have special expertise in how the computer works after installing Linux.
at first Linux wasn't everyone's
Other popular software companies sell you CDs or a set of floppy disks and a short manual, perhaps you can install a fully operational operating system on your computer in one hours. All you need is the ability to read. Those companies had this intention when they sat down to develop their operating system. Linus Torvalds did not think of this when developing Linux. This is just one of his hobbies. Later, companies like Red Hat implemented Linux as an operating system that could be installed as easily as other operating systems; Everyone can install it as long as they follow some simple commands. For some reason, Linux has not completely escaped its previous shortcomings. This is mainly because popular technology publishers are unable to explain in a meaningful way what Linux is. In fact, some tech reporters and Linux have real life experiences and are embodied in their writing.
where's Linux today?
today, Linux is immersed in most of its favorable news. This comes from the fact that Linux has proven to be a very stable and universal operating system, especially as a Web server. When Linux is deployed as a Web server or enterprise network, its downtime is negligible. There are cases in which Linux servers have been running for a short period of a year without restarting, just downtime to be used for routine maintenance. Its cost-effectiveness is higher than any other system. Linux can be installed on a home PC or on a Web server as a fragment of other company package costs. Higher can be relied on and less expensive-this is its ideal. If you're reading this question, obviously what you're going to do next is learn how to use Linux. Any learning experience means new ideas and new ways of doing things. As mentioned earlier, Linux is a member of the UNIX operating system family. UNIX is primarily designed for professionals to use. You're going to learn a lot about UNIX concepts, but that doesn't mean that Linux is an operating system that only professionals can use. In fact, most mainstream versions of Linux are designed to be user-friendly and easy to install, just like any other operating system on the market. Now that you know what Linux is and how good it is, there's one more thing to do-install linux!
