10 most common questions about Linux

If you want to try a desktop system other than Mac and Windows
, Linux should definitely be your first choice. It is not only free, but also customizable. Similar to the Android system of a smartphone, you can also customize what you want on Linux. Before you get into the Liunx system, you should know some basic things about Linux. Here, we have compiled the 10 most frequently asked questions about Linux OS
.

1. What is Linux?

When someone asks this question, the Linux he asks is usually accompanied by another term, such as Fedora Linux, Ubuntu Linux, Android Linux technical support, etc. There are countless examples. So what is Linux? “Linux” refers to the Linux kernel, which is the interface between application software and computer hardware. The various Linux nouns mentioned above have one thing in common. They use the same kernel as the interface between hardware and software. Therefore, “running Linux” in a computer means running the operating system with Linux as the kernel.

You may come across some people who insist that Linux should be called GNU /Linux. This means that for most Linux operating systems, a large portion of the code from the GNU project will be used. Without it, the Linux kernel itself will not work. Therefore, GNU /Linux is the proper name for its structure. For the sake of simplicity, we refer to all operating systems that use the Linux kernel as Linux.

2. Why is Linux free?

Most people know that Linux is a free operating system, and the free reference here is not costing. Yes, not only that, but this free also includes freedom of speech, which means that the source code of Linux can be observed, researched and modified, and even you can copy your favorite code for sharing.

Comparing Windows and mac OS X, the two are still in a non-open source state, which means you can't systematically learn them and distribute them freely. One of the main reasons for this openness of Linux is that the derivative of the Linux operating system has already been successful. Early open source enabled many individuals and enterprises to build their own derivative versions of Linux.

3. What is a Linux distribution?

Distro refers to a configuration of the Linux operating system that the group or company builds by decompressing it. Currently popular Linux distributions include Ubuntu, Fedora, OpenSUSE, and more. Although they all use the Linux kernel, they contain different software configurations. From the default software to the user interface and experience, no two distributions are the same.

Each release can bring different things and provide a specific feature set for a specific user. However, for a beginner, what is most needed is a distribution that provides a simple user experience. Here, I recommend the Ubuntu Linux distribution because it's relatively easy to set up and use, and it offers a variety of support.

4. Does my hardware support Linux?

In the past, hardware support for Linux was uneven, and many components and peripherals were not working properly. Fortunately, most of the previous Linux distributions running on modern hardware are basically fine, so you don't have to worry too much about this.

I said "there is no problem at all" because you still have a small chance of encountering individual problems while running it. While the Linux community has done a lot of work to make sure your current hardware is running the Linux operating system, you may still have an accident. At this time, you must use the troubleshooting guide or replace a Linux-specific driver hardware.

5. Can I try it before installing Linux?

The great thing about most Linux distributions is that you can try it out before installing it. The Linux vendor gives you an easy way to try out the operating system with the mdash;—Live CD. Download an ISO (disc image file) and run it through a virtual drive, where you can try it before installing the distribution.

If you decide not to install Linux, use it as a backup system. (Prepare a system, be prepared) You can create a Live USB. Like the Live CD, Live USB is a bootable USB driver that boots Linux on most computers. This way you can install Linux without the experience of installing an operating system.

6. What is a desktop environment?

When you look at all the different distributions, as you may have noticed, not all Linux operating systems have the same look and feel. This is because they use different desktop environments, such as GNOME, KDE, Unity, and so on. This is like the Aero in Windows 7 and the Aqua in OS X. The desktop environment manages the overall sense of the operating system, the way it feels and how it is used. Different desktop environments have different characteristics and actions.

The most popular desktop environment at the moment, the desktop environment that comes with most distributions is mainly GNOME and KDE. For everything in Linux, if you don't like it, you can change it freely. If the pre-installation environment you choose is not suitable for your taste, you are free to install the style of your choice.

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

There are currently no Mac applications running on Linux, but there is a way to run some applications on Windows. You can use a program called Wine that allows some of your Windows applications to run on Linux at or near the original speed. However, not all programs can run, and even if they are run, you may encounter some incompatibilities such as graphics or functional failures that can't work.

Wine can be downloaded and installed for free, but it is harder for beginners to use. In this case, using third-party tools makes Wine easier to use, and its pre-configuration allows software running on Windows to run more smoothly on Linux. CrossOver Linux is a classic example.

8. How do I get an application on Linux?

Now you have a newly installed Linux operating system, naturally you will want to see what the application above will look like. Installing an application on Linux will have a different experience than on Windows or Mac. The difference between the two is that on Windows or Mac your application should be a file ending in EXE or DMG, and on Linux you must use the repository of the distribution to search for what you are looking for.

Most installs make search lookups easy through GUI navigation, while Ubuntu does this by creating your own app store. Sometimes you may not be able to find what you are looking for in the current repository. In this case, all you have to do is add another repository that contains the project you want. Thanks to the unique repository system, application updates are made easier, and the operating system can find and update all installed applications in one go instead of doing one thing at a time.

9. How can I get technical support for Linux?

Like you start using Windows or OS X for the first time, you will want to learn a bit about Linux when you start using Linux. The problem with how Linux is installed and used is very simple, as most distributions value the ease of use of end users. For those relatively simple computing tasks, such as web browsing and word processing, you will not be confused by Linux.

It may take some time when you solve operating system problems. But don't worry, Linux has a lot of fans and communities to deal with any problems you might encounter. In most cases, troubleshooting Linux is not going to be difficult, and many problems can be solved by step-by-step help from the community by typing command line commands.

10. After installing Linux, can I still run the previous operating system?

After you have installed Linux, you will think this is a good operating system, and you will find that many of them are better than the previous system. However, often many games and other applications cannot run on Linux or Wine. Don't worry, you can use a virtual machine or a dual system to make good Linux coexist with your favorite operating system.

With a virtual machine, you can have both a fish and a bear's paw, allowing Linux to run at the same time as the default operating system. You can run Linux or the operating system you need on a virtual machine, depending on which system you use, which is very resource intensive. Another method is to use a dual system. After the system is restarted, it is free to switch between the two systems. Both methods are very good, it can help you not have to face the difficult choice of the two can only choose one of them
