Do You Know? Linux

Linux is a free open source program under the GNU license, 32-64 bit operating system, which is a derivative of Unix and can be run on a variety of hardware platforms ranging from Intel (x86), to the RISC processor. Linux as a free open source program that makes Linux One famous is because it is free. With the GNU (Gnu Not Unix) You can obtain a program, complete with source code (source code). Not only that, you are granted the right to copy as much as you want, or even change the code source. And was all legal under the license. Although free, GNU license allows a party seeking to attract fee for copying and sending the program. Full of the GNU license, you can read in Appendix III. GNU translation into Indonesian, while the book is still being done.

Note:
Complete literature about GNU can you read on their web site that is http://www.gnu.org.

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

The most important freedom of Linux, especially for programmer and network administrator, is the freedom to derive source code (source code) and the freedom to change it. This implies a few important things. First Security, which both dynamics.

If commercial software does not allow you to find out source code then you will never know whether the program you buy from them it is safe or not (often called security by obscurity). Your life at the hands of the vendor. And if there are notices about bugs than commercial software is often already too late. With Linux, you can examine the source code directly, along with other Linux users. The rise of Linux users as a community that is open, making the bug will be quickly known, and as quickly as it did the programmer will fix the program. You yourself also determines the appropriate code in accordance with the basic needs of hardware and other software to be implemented. Like a car, you can modify at will, even though the engine, to obtain the desired shape.

Disclosure of the source code also allows the operating system is growing rapidly. If a program with a closed system and only developed by a particular vendor, at most about one thousand to five thousand people. While Linux, with the openness of its source code, developed by volunteers around the world. Known bugs faster and fillings a program (patch) more quickly available. Approach the development of this operating system called Bazaar. In contrast Chatedraal very closed system and only focus on one or two developers only.

In addition, Linux provides a free programming language, complete with a compiler, and program assistants. Some of them are:

• ADA
• BASIC
• C
• C + +
• Expect
• FORTRAN
• GTK, to create GUI applications in Linux
• PASCAL
• Phyton
• Shell Scripts
• TCL
• Perl (Practical Extraction and Report The Language), is often used to create CGI scripts on the web.
