Friend, linux is not far from you.

Article Title: friend, linux is not far from you. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
At present, Linux is not very popular. The main reason for a relatively small number of users is that people only have a simple understanding of Linux, so errors are inevitable. This article will comment on these common mistakes and hope you can have a better understanding of Linux.
　　
I. misunderstandings in installation and configuration
　　
1. the installation process is very complex.
Linux installation is like a nightmare. people who hold this idea are mainly influenced by the installation of Unix systems. Linux is very similar to Unix, so people naturally think that Linux is also difficult to install. In fact, this is not the case. many Linux distributions have a GUI (Graphical installation interface. Enter the corresponding information as prompted and select different software packages. the installer will install the system for you in a short time. It is particularly worth mentioning that Red Hat Linux has a very good installation program. a user who has never been in touch with Linux can install the system within 20 minutes. The installation process of Red Hat Linux is even simpler than that of Windows 9x.
　　
2. install Linux with expert guidance
The reason for this idea is the customization of the Linux system. If you want to install a system, you must modify and recompile the source program. In Unix systems, these jobs can only be done by developers. However, this is not the case when installing Linux. Each Linux release provides users with a complete binary executable software package, and users do not need to make any changes at all, you can install it on your own machine.
3. no daily application software is available on Linux.
Totally wrong! Each Linux release contains hundreds of free software and commercial application software. System development kits, Internet servers, client software, daily office software, related Microsoft tools and game software. For example, Red Hat Linux 6 includes about 500 software packages. Many Linux developers in China have installed the most commonly used tool software when releasing the latest Linux system, so there is no need to worry about the absence of available software. If there are so many applications in other operating systems, it may take a lot of money.
　　
II. incorrect opinions on the system
　　
1. Linux runs slowly
Some DOS programs seem to run faster than Linux programs, mainly because DOS is not a multi-task operating system. In fact, NT is slower than DOS when running some programs, for the same reason. However, compared with the two multi-task operating systems, NT is far from running fast in Linux.
　　
2. frequent Linux crashes
Users who have such ideas must be not very familiar with Linux. Currently, Linux and UNIX in network operating systems occupy 60% of the market space. Because Linux can compile the kernel by itself and install the most appropriate driver for different computer hardware, its stability and speed are incomparable to Windows. Generally, Linux hosts can run stably for at least two years without interruption. do you think your computer has such performance?
　　
3. the Linux operating system is too large.
One operating system has two major advantages: One is that there are too many hardware drivers and the other is that there is too much memory. DOS is much smaller than Linux, but it cannot do more for you. Now let's look at Windows 9x, which is also a very bloated operating system. Like Linux, the driver occupies a lot of hard disk space. Linux stores many things in the hard disk after packaging. when used as a workstation, Linux occupies about MB of hard disk space, the installed software includes all the tools, development systems, and Internet servers. In terms of memory usage, Linux occupies a small amount of memory. generally, 4 MB physical memory is enough for running character applications. in this case, linux can give full play to its powerful functions. In contrast, Windows 9x cannot run any program in 4 MB.
　　
4. Linux networking is not easy
Mac uses AppleTalk, Novell's Netware uses IPX, and the most commonly used protocol in the Internet is TCP/IP. Linux supports all the preceding protocols. It is not difficult to connect Linux to the existing LAN. Today's Linux version has integrated all the tools for network installation, just as it is convenient to install the network on Windows. Since there are many Linux developers, new versions of Linux are released every year, and the functions of each new system are enhanced. I believe that Linux networking will become easier and easier.
　　
5. Linux is an insecure operating system.
On the contrary, Linux is a secure operating system. It is precisely because it is an open-source system that all programmers in the world can fully parse its code, therefore, many of the errors and codes that may contain insecure elements can be promptly detected and corrected. The source code of the Windows operating system is completely closed, and the defects exist. if developers cannot find the defects, they can be exploited by hackers. In recent years, Windows operating systems often have bugs that cause security problems, but Linux has very few. Therefore, there are more and more ISPs using Linux systems around the world.
　　
3. prejudice against application software and development software
　　
1. there is no suitable office software or other software available in Linux
Currently, all Linux systems are integrated with modern office software. Users can download the latest version from the Internet. Currently, Office kits that can run in Linux include: Applixware, StarOffice, Word Perfect, and other software packages compatible with MS Office. Chinese Linux vendors integrate such software when releasing Linux. they only need to install the software completely to obtain all the latest popular software.
　　
2. Linux does not support Java
Like other Unix systems, Linux integrates Java interpreters in the kernel and fully supports Java applications. You can write, compile, and execute Java Applets in Linux, and add it to the WWW page.
　　
3. it is difficult to develop Linux applications.
This statement is unfounded. When you get any release package in Linux, it contains many compilers. It also contains the programming environment of the development window, and provides all functions that should be available in similar integrated development environments, such as highlighted display and compilation of user syntaxes. At the same time, the function libraries provided by the operating system support the basic functions required for sound and graphics development.
　　
4. Linux does not provide technical support
The Linux community provides the best technical support for Linux. Most commercial software provides technical support calls at a specified time, and the user's questions can only be answered by one or a few engineers. Linux is different. users get support from many experts in the Linux community. Of course, if you like traditional telephone support, you can call technical support from any Linux manufacturer in China.
　　
IV. misunderstanding of Linux compatibility
　　
1. Linux can only run on PC
Linux is made on a PC and fully compatible with Unix. Although it is quite popular on PCs, it does not mean that it can only run on PCs. Now, Linux has been able to run on Alpha machine, iSCSI, untrliscsi workstation. It can even run on a large computer, and mastering Linux is truly computer-proficient.
　　
2. Linux can only run executable programs in the system
Linux contains DOS and Windows simulators. you don't have to worry about using Windows software in Linux.
　　
3. Other operating systems cannot run in Linux
Linux not only supports other operating systems on the same hard drive, but also supports their file systems, including installing multiple OS on the same disk. Linux LILO can load Linux, DOS/Windows 95, OS/2, etc. Linux allows you to Mount partitions of other operating systems to the system to perform read and write operations on these file systems. For example, you can mount a DOS partition to a Linux system to read and write it.
