what is linux operating system

The computer operating system is a platform for managing computer software and hardware resources. Without it, no computer can run normally. The mainstream operating systems on the market include Windows, Unix, Linux, and Mac OS X.

Linux was developed by Finnish college student Linus in 1991. It is a Unix-like open source operating system with the following main features:

Open operating system (Recommended learning: linux tutorial )

Linux is a free software. Developers can freely install and modify the source of the software freely Code, compared to the command line operation of Unix, Linux provides a window management system, which is relatively easy to operate. Enterprises can use Linux for free, which greatly reduces the cost budget.

Powerful hardware support

Linux system is very easy to maintain. Users can centrally update the operating system and all installed software, which is safe and efficient.

Linux can effectively utilize system resources, allowing users to install for specific hardware requirements, allowing Linux to be installed on old computers, thus helping to make optimal use of computer hardware resources.

High security and stability

Under Linux system, unless the user logs in as root, the program cannot change the system settings and configuration. It is rare that the user mistakenly The operation causes the computer to fail to start.

The permissions of files and malware downloaded from Linux will be restricted, which can effectively avoid virus intrusion. Common ransomware viruses and worms in Windows systems cannot run under Linux.

Linux is very stable and not easy to crash. Linux can maintain the same running speed after a few years as when it was first installed. On the other hand, Windows may not be able to keep up with the speed after running for half a year.

Linux usage scope

is mainly used in personal computers and servers. As an enterprise-level server, Linux is usually used in database servers, load balancing servers, mail servers, DNS servers, proxy servers, routers, etc. It not only allows enterprises to reduce operating costs, but also obtains the high stability and stability brought by Linux systems. High reliability, and no need to consider the copyright issues of commercial software.

In recent years, due to its stable, open source, free, safe and efficient characteristics, Linux has developed rapidly, accounting for more than 80% of the server market. With the development of cloud computing, Linux will play an important role in future servers and personal computers. The field is still the general trend.
