Linux: A Good Example of Open Source Software

The operating system kernel of Linux, also called the Linux kernel, was designed and created by Linus Torvalds in the year 1991. Since then, its popularity has increased dramatically. According to a survey conducted in June 2010, the market share of Linux was 4.8%. Market share has risen by 0.3% since May 2010, indicating that the popularity of Linux continues to grow.

Free and Open Source Software

Linux is one example of free and open source software one can get on the internet. Free and open source software is licensed software to grant users the right to use, study, modify, and improve their design through the availability of their code. All underlying Linux source code may be used, modified, and redistributed, for business purposes or otherwise, under the GNU General Public License. The R-studio for Linux is the most effective and very cheap data recovery software for the R-TT based on the Linux operating system.

Linux Design

Linux is grouped under the Unix family. Much of its basic design is derived from Unix design principles. Linux uses a monolithic kernel, called the Linux kernel. The Linux kernel manages networking, process control, access to peripherals and files. Generally, device drivers are integrated directly into the kernel. Another option is to add a device driver as modules while the system is running. Separate projects interfaced with the kernel provides the superior functionality of the system. The graphical interface has been designed on the model of the Windows X system.

Linux User Interface

Linux provides both a command line interface and a graphical interface to its users. The default mode for workstations is the graphical user interface. Most low-level Linux components use the CLI. The command line interface is suitable for automating repetitive tasks because it allows secure inter-process communication. The Linux desktop command-line interface is accessible through a graphical terminal emulator. The KDE plasma desk, GNOME and Xfce are the most popular user interfaces among desktop systems. Windows X systems have designed many preferred user interfaces.

Linux Programming

Linux supports most programming languages. The GNU toolchain contains most utilities, including the GNU Compiler Collection and GNU Build. GNU gathers all the Collection that consists of Ada, C, C ++, Java, and FORTRAN compilers. Apart from that, Linux supports the Intel C ++, IBM XL C / C ++ and Sun Studio grouper including all dynamic languages, Perl, Python, PHP, and Ruby.

Linux Kind of Applications

Linux operating system usage is not only restricted to desktops and servers, but also for support of IT architecture, real-time applications, embedded systems, and more. I can boldly say Linux is the most widely used operating system kernels worldwide. The Linux kernel can run on a wide range of computer architectures, including ARM-based iPAQ systems, IBM Z9, and Z10 mainframe systems, and more. Some functional Linux distributions have been designed to work on less popular traditional architectures. ELKS fork has been developed to run on a 16-bit Intel x86 processor architecture.

The Linux kernel could also be configured to run on Apple Macintosh computers based on Power PC and Intel processors, portable music players, video game consoles and smartphones. PC support for Linux machines is widely available nowadays in case a Linux machine does not work correctly. In addition to PC and small applications, Linux distributions are also used as server operating systems. The use of Linux has increased on mainframes because of economic factors and availability of remote support.
