What is Linux ?

Linux is an open source program that is free under the GNU license, 32-64 bit operating system, which is a derivative of Unix and can be run on many different hardware platforms from Intel (x86), to the RISC processor. Linux open-source programs as the free one that makes Linux is popular because it's free. With the GNU license (GNU Not Unix) you can get the program, complete with source code (source code). Not only that, you are given the right to copy as much as you want, or even change the code sumbernya.Dan that all legal under license. Although free, the GNU license to allow the parties want to attract cost for multiplication and delivery program. Full license from the GNU, you can read in Appendix III. GNU license translation into Bahasa Indonesia, the book is still done.

Note:

Literature about the complete GNU you can read in their web sites, namely http://www.gnu.org.

Thus, it can be said that you can get Linux, without having to pay at all. If you must pay each time you install the software on another computer, then with Linux you can install anywhere without having to pay license.

Freedom of the most important of Linux, especially for a programmer and network administrator, is the freedom to obtain the source code (source code) and the freedom to change it. This is for the several important issues. First, security, the second dynamics.

If commercial software does not allow you to know the code sumbenya then you will never know whether the programs that you buy from them is safe or not (often called security by obscurity). Your life in the hands of the vendor. And if there is a notice about the bug from commercial software is often already too late. With Linux, you can examine the source code directly, along with other Linux users. The development of Linux users as a community that is open, make the bug will be known quickly, and as soon as is also the programmer will improve the program. You also determine that the code of the match in accordance with the hardware and basic software to be implemented. Like a car, you can modify they can, even though the engine, to obtain the desired form.

Openness source code also allows the operating system grew rapidly. If a program with the system closed and only developed by a particular vendor, at most about a thousand to five thousand people. Meanwhile, Linux, the openness with the source code, developed by volunteers all over the world. The bug is known more quickly and penambalnya program (patch) more quickly available. Approach to the development of this operating system called Bazaar. Kebalikannya system Chatedraal very closed and only centered on one or two developers only.

In addition, Linux provides a programming language for free, complete with kompilernya, and the program pembantunya. Some of them are:

* THERE
* BASIC
* C
* C + +
* Expect
* FORTRAN
* GTK, to create GUI applications on Linux
* Pascal
* Phyton
* Shell Scripts
* TCL
* Perl (The Practical extraction and Report Language), often used to create CGI scripts on the web.
