Linux has the following common applications:

· Desktop computers:

The so-called desktop computer is a common operating system for general users when working in front of the screen! We call it a "Desktop" system. it is short for Desktop computers! When it comes to desktop computers, you cannot mention X-Window System.

O from the history of Unix and Linux mentioned in the previous chapter, we know that the Windows screen of the United States appeared on Unix in 1986. at that time, the window screen was referred to as the X system, then it came to 1994 and was officially integrated into Linux! Microsoft Windows only appeared in 1995!

O the so-called X Window System is a set of Window interface software that manages and displays the core of the X11 Window software released in the XFree86 project, it is often abbreviated as a Graphical User Interface ). This XFree86 is just a set of software on the core of Linux. his main job is to manage the output of graphic interfaces, and almost all display-related hardware controls, for example, the display card, screen, keyboard, mouse, and so on are all managed by XFree86! Alternatively, we can call XFree86 an X-Window System Server.

O as for the beautiful Window image we see, the function of displaying related hardware is used to display the graphic Window administrator (Window Mananger, WM) the ability to play! That is to say, WM is a set of display window interface software that is mounted on X Server. for example, common KDE and GNOME are WM.

So what is this desktop computer doing? To put it simply, the daily work of a desktop computer is:

O online browsing;

O file processing;

O network interface-document processing system;

O Office Software processes data;

O send and receive emails;

That's all! In these jobs, Linux has a beautiful graphic interface X Window System that provides a good user interface (GUI). In addition, WM is also developing with cultural functions! As for Office software, it is supported by software similar to Open Office. Therefore, Linux is sufficient for most Office workers in desktop computer-type use.

· Workstation computer:

Workstation computers are not the same as desktop computers because workstations usually have to deal with important business applications, for example, Engineering Fluid mechanics numeric mode operations, special effects of entertainment, software developers' work platforms, etc. Linux has powerful computing capabilities and a wide range of GCC compilation software. Therefore, it is also a good choice for operating systems in workstations. For example, we need to transfer the large mode executed on Sun Unix to Linux. according to tests conducted by the US Environmental Protection Agency, Linux is not only cheap (X86 system! ) And the speed is still relatively fast!

· Network server:

Thanks to the good Unix tradition, the network functions on Linux are particularly powerful! In addition, due to the GNU program, the server software on Linux is almost free! Therefore, as a network Server, such as WWW, Mail Server, File Server, and FTP Server, Linux is definitely the top choice!

· Embedded system:

In recent years, the electronics industry has been booming, with the development of small-sized microcomputer being very important, such as household appliances, PDAs, and other micro-computers, these computer equipment is usually directly embedded in the product, for example, PDA itself is a small computer operating system! These systems are called embedded systems. to make these embedded systems act, we naturally need to create a simple operating system. at this time, linux, which can modify the core to make the function simpler, is a good choice. Therefore, in recent years, many embedded systems have chosen Linux as the development platform.
