In what fields does Linux have wide applications?

The application fields of Linux include IT server Linux system applications, embedded Linux system applications and personal desktop Linux applications; Linux is a set of open source code programs and a Unix-like operating system that can be freely disseminated Software, with the updates and changes in information technology, the application fields of Linux have become more extensive.

In what fields is Linux widely used?

Like Windows operating system software, Linux is also an operating system software. But unlike Windows, Linux is a set of open source code programs and UNIX-like operating system software that can be freely disseminated. With the updates and changes in information technology, Linux application fields have become more widespread.

1. Application field of IT server Linux system

Today's IT server field is divided into three parts: Linux, UNIX, and Windows. Linux system can be said to be a rising star. Especially in recent years, server-side Linux operating systems have continued to expand. The market share is growing rapidly every year and poses a serious threat to the status of Windows and UNIX server markets.

Linux is widely used as an enterprise-level server. Linux systems can be used to build WWW servers, database servers, load balancing servers, mail servers, DNS servers, proxy servers (transparent gateways), routers, etc. for enterprises. Not only This enables enterprises to reduce operating costs while also gaining the high stability and reliability brought by Linux systems.

With the widespread application of Linux in the server field, judging from the development in recent years, the system has penetrated into various industries such as telecommunications, finance, government, education, banking, and petroleum. At the same time, major hardware manufacturers Also supports Linux operating system. All this shows that Linux has a bright future in the server market. At the same time, large and very large Internet companies (Baidu, Sina, Taobao, etc.) are using the Linux system as their server-side program running platform. Almost the top ten websites globally and domestically use the Linux system. Linux has gradually penetrated into in enterprises in various fields.

　2. Embedded Linux system application fields

Because the Linux system is open source code, it is powerful, reliable, stable, flexible, and has great scalability. In addition, it Extensive support for a large number of microprocessor architectures, hardware devices, graphics support and communication protocols, therefore, in the field of embedded applications, from Internet equipment (routers, switches, firewalls, load balancers, etc.) to dedicated control systems ( Vending machines, mobile phones, PDAs, various household appliances, etc.), the Linux operating system has a broad application market. Especially after several years of development, it has successfully become a mainstream embedded development platform. For example, in the field of smartphones, Android Linux has firmly occupied a place in the smartphone development platform.

　3. Personal desktop Linux application field

The so-called personal desktop system is actually the personal computer system we use in the office, such as: Windows XP, Windows 7, MAC, etc. The Linux system's support in this area is also very good, and it can fully meet daily office and home needs, such as:

Browser for Internet browsing (such as: Firefox browser).

Office software (OpenOffice, compatible with Microsoft Office software) processes data.

Send and receive email (for example: ThunderBird software).

Real-time communication (for example: QQ, etc.).

Text editing (for example: vi, vim, emac).

Multimedia applications.

Although the support for Linux personal desktop systems has been very extensive, the current desktop market share is far from being able to compete with Windows systems. The obstacle may not lie in the Linux desktop system product itself, but in the users. usage concepts, operating habits and application skills, as well as porting issues for software once developed on Windows.
