Much is said in the operating system Linux, that increasingly has conquered new horizons and reaching an increasing number of users. If you have no idea of how this system works and is, acompanhe esta matéria desenvolvida pelo Grupo Dicas em General.

After All, What is Linux?

THE Linux is an operating system, i.e., an interface that manages the computer and makes it possible for your interaction with the user. So, Linux controls the management of physical devices (as memory, hard disk, processor, between other) and allows programs to use for many different tasks. Other operating systems include: the BSD UNIX family (FreeBSD, NetBSD, OpenBSD and other), AIX, HP-UX, OS/2, MacOS, Windows, MS-DOS, and many other options.

linus torvaldsThe creator of Linux kernel is called Linus Torvalds. When the kernel was created, followed the POSIX operating standards – the same used by all UNIX systems – and so it's an operating system much like the other UNIX family (but not equal). A curious fact is the origin of the name Linux: the author has joined its Unix name (Linus + Unix) and the resulting was Linux.

One of the features that made it the most popular Linux is its high portability, that causes the system can be used on various hardware platforms: PCs, main-frames, Enterprise servers, embedded systems, mobile phones, handhelds, routers, electronic voting machines, among others. In addition, It is a complete operating system, multi-threaded, multi-user, which means that multiple services and users can use it at the same time. Another important feature is its high ability to chat with other operating systems, such as other UNIX systems, Windows networks, Novell, and other more.

Besides all these features, one of the main and most important features of Linux is that it is a free software (Open Source – or in Portuguese – open source). This means that you don't need to pay to use it, In addition to having the option of not relying on any company that controls the operating system. The source code for the core system (kernel) is released under the GPL license and can be obtained on the Internet by anyone, You can also have your code changed and re-distributed, modifying your tastes and your needs, If you need to. By be free, Linux has how many developers programmers around the world, from several different companies or individuals, contributors always sending pieces of code and implementations to Linus Torvalds, who organizes and decides what going to the official kernel or not.

Distributions

Linux is subdivided into distributions, i.e., different versions of the operating system, modified to provide end users with specific resources, are they: educational, Office applications, internet, games and more.

Among the major Linux distributions we can highlight widespread greats, as: Debian, Ubuntu, Slackware, Mandriva, OpenSUSE, Kurumin and many other.

Knowing more about Linux

If you bought your computer now and don't know how to mess with Linux, It is clear that the first idea is: mechendo skirt and discovering resources. But this is not always an animator, especially if the system is very different from what you're used to socialize and interact. Therefore, We recommend that you read This book (Click here), so you have a more specific notion of Linux and its features.

Remembering that for each distribution there are different resources, and with each new version of such distributions are new features added and others removed. Always try your operating system documentation for the main menu or via the internet.
