Today, I would like to talk to you about how to understand Linux. Many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something from this article.

When you come into contact with Linux for the first time, it is necessary for readers to know what Linux is, the development status of Linux, various versions of Linux and the correct learning methods of Linux. Understanding this knowledge can lay a solid foundation for readers' follow-up study.

Let's start with an understanding of what Linux is and in what areas it is used.

What is Linux?

Most readers may have heard of Linux, but what exactly is Linux? I believe this is the common doubt of most readers who have just come into contact with Linux.

Linux belongs to the UNIX operating system, which was released by Linus Torvalds in 1991. because of its free and open source code, people will combine with user space applications to develop into the current Linux operating system. Linux is a complete operating system based on the Linux kernel that includes GUI components and many other utilities.

At this point, I have to introduce GNU (General Public License, General Public license Agreement). GNU is a widely used free software license agreement, which not only gives the definition of free software to computer programs, but also requires the release of any software development and derivative products in the form of GNU license, but also requires the disclosure of source code.

Linux is well known for its free and open source code. For now, as long as you follow the GNU General Public license, any person or organization is free to use all the underlying source code of Linux, or to modify and redistribute it. With the rapid development of Linux operating system, a variety of open source software and utilities integrated on Linux have also been applied and popularized. therefore, Linux has also become synonymous with open source software.

The application field of Linux

So what exactly can Linux be used for? Several common application areas of Linux are listed below:

Development in the field of servers

With the emergence of Linux operating system, the influence of open source software in the world is gradually increasing. In the whole server operating system market pattern, Linux operating system occupies more and more market share, and maintains a rapid growth trend, especially in the key areas of the country.

According to statistics, at present, Linux operating system has occupied a large market share in the server field, so it has also aroused great concern in the global IT industry, and has become the backbone of the server operating system field with a strong momentum.

2) the development of desktop field

At present, the development trend of Linux desktop operating system in China is extremely rapid, such as Kirin Linux, Red Flag Linux, Deep Linux and other Linux desktop operating systems, have been widely used in major enterprises.

However, there is still a certain gap between Linux desktop operating system and Windows system, which is mainly reflected in the overall function and performance of the system, including the ease of use of the system, the management of the system, the compatibility of software and hardware, the richness of software and so on.

3) the development of mobile embedded field

Linux has also been widely used in embedded systems, which is mainly due to the low cost, powerful customization function and good porting performance of Linux operating system, which makes it widely used in tablet computers, mobile phones, televisions and other fields. For example, the Android operating system we use now is also created on the Linux kernel.

In addition, customized Linux is also used in network firewalls and routers, as well as some smartphones, tablets and network televisions, common digital video recorders and stage lighting control systems are gradually using customized versions of Linux to achieve.

4) the development of cloud computing / big data

With the rapid development of the Internet industry, cloud computing and big data industries have formed and developed rapidly. Cloud computing and big data are platforms based on open source software, in which Linux occupies the core strength.

According to the research of Linux Foundation, most enterprises have used Linux operating system to build cloud computing and big data platform. At present, Linux has begun to replace UNIX as the most popular cloud computing and big data platform operating system.

What is Linux system Linux is a free-to-use and free-spread UNIX-like operating system, is a POSIX-based multi-user, multi-task, multi-threaded and multi-CPU operating system, using Linux can run major Unix tools, applications and network protocols.

After reading the above, do you have any further understanding of how to understand Linux? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
