Top ten most common issues in Linux

As a free operating system, Linux can be a popular system that replaces Windows and OSX platforms. Even so, many people think that they have never been in touch with Linux, while the commonly used & ldquo; Android & rdquo; smartphone system is provided by Linux technical support, because the Linux code is universal, it can meet almost any user's needs. If you want to try a desktop system other than Mac and Windows, Linux may be your first choice.

As a free operating system, Linux can be a popular system that replaces Windows and OS X platforms. Even so, many people think that they have never been in touch with Linux, while the "Android" Smartphone system is usually provided by Linux for technical support. Because the Linux code is universal, it can meet almost any user's needs.

If you want to try a desktop system other than Mac and Windows, Linux may be your first choice, not just because it is free, but focuses on its customization. Similar to the Android system of smart phones, you can customize the applications you need on Linux. Therefore, you need some basic Linux knowledge about the Linux system. I have sorted out and shared the 10 most common issues about the Linux operating system.

　　1. What is Linux?

When talking about Linux, it is usually associated with a series of Linux technologies such as Fedora Linux, Ubuntu Linux, and Android. So what is Linux? "Linux" refers to the Linux kernel, which is an interface between application software and computer hardware. As mentioned earlier, Linux terms all share one thing in common and use the same kernel as an interface between hardware and software. Therefore, running Linux on a computer means running the operating system with Linux as the kernel. Linux Kernel (Image Source: hongkiat.com, the same as below)

Most people think that Linux should be called GNU/Linux. This means that for most Linux operating systems, a large part of the code from the GNU project will be used to make the Linux kernel run effectively. Therefore, GNU/Linux is a description of its structure, and we usually call all Linux operating systems that use the Linux kernel as Linux.

　　2. Why is Linux free?

As we all know, Linux is a free operating system. Here free refers not only to money, but also to freedom of speech. This means that the source code of Linux can be researched and modified by everyone, you can even copy your favorite code for sharing. Free Software

Compared with Windows and mac OS x, Windows OS X is not open-source, which means that users cannot systematically learn and freely allocate resources. One of the main reasons for the openness of Linux is the success of the derivative version of the Linux operating system. The early open-source technology enabled many individuals and enterprises to build their own Linux derivative versions.

　　3. What is the Linux release?

The so-called release version (distro) refers to a configuration method of the Linux operating system. The company uses it to decompress it to build Linux. Popular Linux distributions include Ubuntu, Fedora, and OpenSUSE. Although all linux kernels are used, the software configurations are different. From the default software to the user interface, no two releases are the same. Many Linux distributions

Each linux release provides a specific set of functions for specific users. However, for beginners, the most important thing is to provide a release version that provides a simple user experience. Ubuntu Linux is widely supported by users because it is relatively easy to set and use and provides multiple types of support.

　　4. Does the hardware support Linux?

The hardware has different support for Linux, and many components and devices cannot work normally. With the continuous improvement of technology, most Linux distributions now run on modern hardware without any problems. Linux and hardware

But "basically no problem" does not mean completely, sometimes there is a very small chance of problems running linux. Although the Linux community has done a lot of work to ensure that the current hardware can run the Linux operating system, there may still be unexpected situations. Users and enterprises must use the troubleshooting guide or replace a Linux-specific driver hardware.

　　5. Can I try it out before installing Linux?

For most Linux distributions, you can try it out before installation. Linux vendors provide a simple method-Live CD to try out the operating system. Download an ISO (CD image file) and use the virtual optical drive to run it. You can try it before installing the release. Try Linux

For the official version, if you decide not to install Linux, but use it as a backup system. You can create a Live USB. Like Live CD, Live USB is a bootable USB driver that can run Linux on most computers. you can install Linux without operating system installation experience.

　　6. What is a desktop environment?

Not all Linux operating systems have the same appearance when facing different releases. Because different desktop environments are used, such as GNOME, KDE, and Unity. Like Aqua in Aero and OS x in Windows 7, it makes the desktop environment manage the overall senses and usage of OS, so that different desktop environments have different features and application methods. Desktop Environment

Currently, the most popular desktop environments are GNOME and KDE, which are included in most releases. All applications in Linux can be freely changed. If the Pre-installation environment of the release you selected is not suitable for your requirements, you can install the selected style as needed.

　　7. Can I run Windows/Mac applications on Linux?

Currently, Mac applications cannot be run on Linux, but some applications on Windows can be run in one way. You can use a program called Wine to make some Windows applications run on Linux at a good speed. However, not all programs can run, and even if they are run, some incompatibility or functional faults may occur, resulting in failure to work.

Windows/Mac applications can be run on Linux.

 

Wine can be downloaded and installed for free, but it is difficult for beginners to use. In this case, the use of third-party tools can make Wine easier to use, and its pre-configuration can make the software running on Windows run more smoothly on Linux, crossOver Linux is a typical example.

　　8. How do I obtain Linux applications?

For a newly installed Linux operating system, will the above applications have a different experience than Windows or Mac? Different from the two, on Windows or Mac, your application should be a file ending with EXE or DMG, in Linux, you must use the release repository to search for the required content. How to obtain Linux applications

Most distributions use GUI navigation for search, while Ubuntu creates its own app store. If you cannot find the required content in the current repository, all you need to do is add another repository that contains the project you want. Because of its unique Repository System, application updates become easier, and the operating system can find and update all installed applications in one breath.

　　9. How to obtain the technical support of Linux?

Just as when I first started using Windows or OS x, I would like to learn about Linux when I started using Linux. It is very easy to install and use Linux, because most distributions place great importance on the usability of end users. For relatively simple computing tasks, such as web browsing and word processing, using Linux will not cause any obstacles. Obtain technical support from Linux

However, it may take some time to solve the operating system problems, while Linux has a large number of fans and communities enough to cope with any possible problems. In most cases, troubleshooting for Linux is not very difficult. For many problems, you can solve them through step-by-step help in the community by typing the command line command.

　　10. Can I run the previous OS on Linux?

Once Linux is installed, you will think this is a good operating system platform, and even many things will be better than the previous system. However, many games and other applications cannot run on Linux or Wine. However, excellent Linux systems can coexist with other operating systems through virtual machines or dual systems.

For virtual machines, you can switch between Linux and the default Operating System at the same time. Running Linux or other operating systems on virtual machines depends on which system is used more frequently, but this method consumes system resources. Another method is to use a dual system. After the system is restarted, you can switch between the two systems as needed.

As a result, as an excellent open-source operating system, Linux desktop applications have developed rapidly in recent years, changing the image of Linux in the past on high-end servers, linux has more desktop effects than vista, and has become an imitation object of win7. More and more companies are turning to linux. In the future, with the increasing variety of linux applications, the user experience will be enriched and improved.
