Linux is a strange operating system born in the network, growing in the network and matures the network.

1. What is Linux?

Linux is a strange operating system born in the network and growing in the network and matures the network. In 1991, Finnish college students Linus Torvalds germinted the idea of developing a free UNIX operating system. In that year, Linux was born, align = "marginwidth =" 0 "marginheight =" 0 "src =" http: //. Chinabyte.com/adjs/iframe-pip/y-software-pip.html "frameborder =" 0 "width =" 360 "scrolling =" no "height =" 300 "> In order not to let this wings unfertile operating system Linus released the work Linux through the Internet. From this large number of well-known, unknown computer hackers, programmers join the development process, Linux gradually grow.

The Linux first is required to require all the source code must be disclosed, and anyone must not be profitable from the Linux trading. However, this pure free software is ideal for Linux's popularity and development, so Linux starts to turn to GPL, becoming a major member in GNU camp.

Now, Linux has gradually expanded from the internationally renowned enterprises such as IBM, Intel, CA, CA, Core, Oracle, and IBM, Intel, Ca, Core, Oracle, and gradually become one of the mainstream system.

2. What is free software?

Since 1984, the Massachusetts Institute of Technology began supporting the "World's last hackers" Richard Stallman launched a free software movement in the software development group, and the free software foundation FSF, GPL protocol, and GNU project were born, opened free software. The chapter of the revolution.

GPL, General Public License Agreement, which is opposite to traditional business software license agreement, so it is called Copyleft. GPL ensures that anyone has the freedom of sharing and modifying free software. Anyone has the right to obtain, modify, and re-release the source code of the free software, and specify that the source code of free software can be obtained without increasing additional fees. At the same time, the derivative of free software must be a license agreement with GPL as it re-issued.

The GNU project's goal is to establish freely published, portable UNIX classes.

3. What is the advantage of Linux?

1) Provide advanced network support: built-in TCP / IP protocol;

2) Trust multitasking, multi-user system;

3) Compliance with the UNIX system, in line with the IEEE POSIX standard;

4) Core energy simulation FPU;

5) Support dozens of file system formats;

6) Fully run in the protection mode, fully utilizing CPU performance;

7) Open source code, users can improve their system;

8) Adopt advanced memory management mechanisms, more effectively utilize physical memory;

4. Do I need to learn Linux?

Computer beginners: I strongly recommend that you stay away from the configuration, the management is quite cumbersome, and hugs Windows, which is easy to understand;

Word handler: Windows has developed for many years, has developed a set of "what you see" text processing software, can't commit crimes with the black-faced VI;

Programmer enthusiasts: Linux's source code is fully open and is the gospel of program enthusiasts. Analyze the core, isn't it your wish? How, try it!

Network administrator: Hug Linux. According to the authority evaluation, Linux is 1.8 times the network service efficiency on the machine, and it is still free, the boss will laugh.

In short, if you have one of the following conditions, embrace Linux:

1) There is mad for the programming, always like to solve the problem;

2) Has a strong drilling spirit, like to plan the problem;

3) People who are interested in constructing network servers;

4) Your PC old teeth, running Windows like snail;

5) I want to learn, understand the UNIX system;

6) Extremely disgusting Windows blue screen crash;

7) Don't want to spend money, and want to use genuine software.

5.Linux will replace Windows 9X?

Computers can be divided into desktop applications (workstation / clients) and server applications, desktop applications directly for customers, implement some personalized work; server applications are some background processing systems to implement some common service work. For desktop applications, ease of use is very important, and for servers, performance is reliable and stable is more important.

So the performance of the server is reliable, the stable UNIX system and the user interface for the desktop system design have always been a long-term coexist mainstream system.

The Linux system is a clan Unix as a system, and its design is much more considered for stability. It is not a desktop system, which is not to replace the desktop system. So Linux will not replace Windows 9x.

6. Who is better for Linux and Windows?

The WindowsNT system is Microsoft to enter the server's tools. When designing the system, the advantages of the Windows 9X's graphical interface are integrated, making it easy to use, and the market share is also So the rising section.

However, the cost of the graphical interface reduces the efficiency of the system, so it is suitable for small and medium-sized enterprises, personal users, and uses unstrue performance requirements.

Linux applies to emphasis on performance indicators, applications that require small user interface requirements.

7. LINUX is different from UNIX?

Linux is also a member of the UNIX family. It has many features that are the same as Unix, and the biggest difference between them is the following two points:

1) Most of the UNIX system is supported with hardware, while Linux can run on a variety of hardware platforms;

2) UNIX is commercial software, while Linux is free software, free, free, public code.

8. What are the fields can I apply?

1) Educational areas: design advanced, public code, this two major characteristics make Linux a living materials for system lessons;

2) Web server domain: stable, strong, system requirements, network function, so that Linux has become the first choice for the Internet Server as the system, and has now reached a cost of 25%;

3) Enterprise Intranet: You can use a low-cost input E-mail server, WWW server, proxy server, transparent gateway, router;

4) Video production areas: The famous "Titanic" is the effect of completing more than 200 Linux collaboration.

9.Linux makes system development status and future? At the 2000 Linuxworld Conference, it is clear that the social distribution of the free release system has greatly enhanced, especially many hardware vendors, such as IBM, HP and Dell added to the Linux field, which greatly promoted This development of the system.

Although it is now complex multi-Linux distribution, each is the array, which reduces the overall combat effectiveness of Linux. But the industry believes that different distributions will eventually produce continuously subdivided markets, each version will focus on the more professional things.

After the Linux has experienced the baptism of the market, it will create greater glory.

10.Linux impact on the software industry?

The earliest, the program is the crystallization of programmer's mind, is a common culture of human beings. Later, Microsoft's founder Bill. Mr. Gates created a new software industry mode: the program is to spend money, the source program is the programmer's intellectual property, it is to protect. The business model of this software creates Microsoft Empire, but also pushes Bill to the world's richest position.

If Microsoft's Windows has made great contributions to the world, then it also brings monopoly and copper stink in the development of the software industry. Free Software FSF organization is to break this pattern through the GNU project, let everyone share the crystallization of programmer's thinking --- source code.

The joining of Linux makes free software organizations more combat, and it has proved that it has a far-reaching impact on the current software industry. At the same time, Linux has also provided valuable experience for the innovation of the software industry.

11. How do I learn Linux?

1) Read more Linux books, such as "Linux Daquan", "Redhat Linux Mystery", "Linux System Management White Paper";

2) Dare to try, often use Linux, learn Linux from practice, don't be afraid of "try again";

3) Frequently communicated with Linux enthusiasts through the network, improve yourself.

12. What are the Linux resources on the Internet?

On the Internet, there are many websites on Linux, and the relatively excellent Chinese website is:

1) www.linuxaid.com.cn: There is a Linux Forum, online Q & A, Knowledge Base, online training, solution and other columns;

2) www.linuxforum.net: Here you should be the most popular Linux forum;

3) www.lslnet.com/linux: is an updated Linux topic website;

4) www.linuxbyte.com: It is a good Linux website;

5) www.clinuxdevelop.org: China Linux Development Alliance;

6) Clyan.hongnet.com:linux Database Application Guide.

13. What version is high if Dear Linux 6.5 and Linux 2.4? Align = "marginwidth =" 0 "marginheight =" 0 "src =" http://images.chinabyte.com/adjs/iframe-pip/y-software-pip.html "frameborder =" 0 "width =" 360 "scrolling =" no "height =" 300 "> Many newspapers, websites, how to introduce Linux's latest version 2.4, what? And many Linux beginners are using the Redhat Linux version 6.5. Which version is higher?

The Linux core is maintained by Linus, and its version number is generally composed of two to three parts, for example, now the most stable 2.2.15:

1) The first 2 is the main version number, which is generally more stable during one period;

2) The second 2 is the secondary version number. If it is an even number, the representative is a formal version. If it is an odd number, the representative is the beta version during the development process. When it is officially out of 2.4, 2.3.x is used between developers. The version number of the beta;

3) The last 15 is a modification number, such as 2.2.15 is a small modification of 2.2.14.

This special version of the nomenclature is to facilitate developing in the Internet.

14. What are the release of Linux?

The Linux distribution is to make a Linux core with the application. More famous: Slackware, Redhat, Debain, Mandrake, SUSE, XLinux, Turbolinux, BluePoint, Redflag, Xterm, etc.

15. What are the characteristics ofRedhat linux?

Redhat Linux is the most mature Linux distribution version, which is a boss in the market, both sales or installed. Almost all of the use of redhat in the Chinese older generation Linux enthusiasts. A large number of articles on the market are for RedHat.

Redhat Linux is simple, simple, stable, is a good platform for business applications and drilling Linux.

I have recently introduced the latest version of Linux. What is the latest version of Linux? And many Linux beginners are using the Redhat Linux version 6.5. Which version is higher?

In fact, these two version numbers are different! Redhat Linux is a release of some common supporting software for Linux kernels and Linux, 6.5 is the version number of this release. LINUX 2.4 refers to the version of the Linux kernel. The Linux core is maintained by Linus, and its version number is generally composed of two to three parts, for example, now the most stable 2.2.15:
