You are thinking of using a Linux, but you don't know from which distribution begin? Or maybe you're looking something for special tasks? Answer the questions to see the Linux distribution for you.
"Linux" is a common name and inadequate if we are talking about a complete operating system, at that Linux itself is only the kernel of the operating system. Therefore, if we mean a complete operating system, the correct name is a GNU/Linux, a set of GNU software in combination with Linux kernel. By shortening the name to "Linux", many people are not aware about the contribution which brought the Free Software Fundation with his a GNU project.
Similarly to the GNU/Linux, we have the GNU/Hurd operating system, which is a set of GNU software in combination with the Hurd kernel (although still in development).
Wondering which Linux distribution is the most popular? Or where to check what they are all Linux distributions in the world? An interesting webside in this aspect is the DistroWatch.com, where you will find descriptions, rankings and search engine of existing distribution of free operating systems software.
Ubuntu is a very popular distribution, especially among beginners with Linux. Perhaps you've heard about Ubuntu. However, very few home users of Ubuntu knows and be aware of that any data entered in the field to search the contents of your computer (eg. when you looking for a private file stored locally on your computer) is sent to the servers of Amazon to suggest us paid offers from this company. This feature is enabled by default, so if you care about your own privacy, you should remember to switch off it.
Update
With the Ubuntu 16.04, this feature is disabled by default.
Widely regarded Linux is the operating system free of viruses. It's not entirely true, viruses on Linux also exist, but their scale compared to eg. Windows is incomparable in favor of Linux. As the Linux is a niche system and therefore for most malware writers, it does not pay to create a pest for this system. Therefore, you can work without running of antivirus in the background. However, you should always be careful and eg. don't open suspicious attachments from the e-mails and maintain a high suspicion and caution.
Many users of the popular Windows often are familiar with programs or games that are created only for Windows. By this it is often difficult to imagine "fly" on Linux. However, there are solutions, such as: Wine (installs Windows environment for Linux allows to install other Windows apps), PlayOnLinux (based on Wine and created mainly for game players), and optionally, you can also install Windows on the virtual machine, for example by VirtualBox.
After all, the best option is to seek and get used to the equally great alternative apps, natively running under Linux. Also, thanks to Steam, we have on Linux more and more games, which operate without unnecessary "combining".
There are hundreds, if not thousands of GNU/Linux distributions which are created by human-enthusiasts around the whole world. For people accustomed to Windows issued every few years, may raise the question "why this is so much?" Well, GNU/Linux is based on the open sources idea, this means that anyone can modify and reproduce GNU/Linux, to introduce their own amendments, modifications, change the appearance/interface and improve at its sole discretion. All this provided that your changes also made available on the same terms to others. That's how open access, creating countless abundance.
On the other hand, such as Windows, it works on the principles of closed code, where anyone under the threat of fines and prisons, do not do anything with it. Therefore, only Microsoft has the rights to create and modify Windows, which lasts longer and reduces the parallel work and independent teams on various modifications and transformations. If Windows was renamed to open source, probably we would see soon a lot of his modifications and various versions, exactly the same as it is now with GNU/Linux.
The picture on the left presents the first Linux logo created in 1992. Then in 1996 Larry Ewing sketched smiling penguin named Tux who officially took over the role of logos and mascots of the Linux.
