Good afternoon ,everyone! I’m ** ,come from ** .Now,I would like to begin my oral presentation It’s about Linux.I divide my presentation in three parts. the first is the introduction of linux, the second is the history of linux , the third is its advantages, the next is its development, the last is its uses. Now ,let’s begin.
The Introduction
The Linux is a Unix-like computer operating system assembled under the model of free and open source software development and distribution. The defining component of Linux is the Linux kernel, an operating system kernel first released 5 October 1991 by Linus Torvalds.
Linux was originally developed as a free operating system for Intel x86-based personal computers. It has since been ported to more computer hardware platforms than any other operating system.
Since the compiler Linux is written with and the main supporting user space system tools and libraries originated in the GNU Project, initiated in 1983 by Richard Stallman, the Free Software Foundation prefers the name GNU/Linux.
The history
The Unix operating system was conceived and implemented in 1969 at AT&T's Bell Laboratories in the United States by Ken Thompson, Dennis Ritchie, Douglas McIlroy, and Joe Ossanna. It was first released in 1971 and was initially entirely written in assembly language, a common practice at the time. Later, in a key pioneering approach in 1973, Unix was re-written in the programming language C by Dennis Ritchie (with exceptions to the kernel and I/O). The availability of an operating system written in a high-level language allowed easier portability to different computer platforms.
The GNU Project, started in 1983 by , had the goal of creating a "complete Unix-compatible software system" composed entirely of . Work began in 1984. Later, in 1985, Stallman started the and wrote the (GNU GPL) in 1989. By the early 1990s, many of the programs required in an operating system (such as libraries, compilers, text editors, a Unix shell, and a windowing systemwere completed, although low-level elements such as device drivers, daemons, and the kernel were stalled and incomplete..
In 1991 while attending the , Torvalds became curious about operating systems and frustrated by the licensing of MINIX, which limited it to educational use only. He began to work on his own operating system which eventually became the Linux kernel
The advantage
Linux can let knowledge continue, emerging software company can fast, low-cost create professional ability from open source , the rich market competition, prevent take over software behemoth existence.Open source Linux can make maintenance continue, can continue accumulated successful, cumulative success can
let software maturity gradually increase, won't have closed source software manufacturer collapse caused by maintenance fault, software orphan problems.
Adaptable, and high degree of freedom, but oneself to create the demand system, the manufacturer (individual) can also according to the hardware limit cuts the kernel, let low-level hardware to suit needs, cost of the system. The same hardware of Mobile phone, Microsoft Windows Mobile with Linux kernel Android contrast, efficiency gap is rather large, Windows Mobile minimum hardware demand than Linux kernel system high on a large margin.so,it is stable, fast and good compatibility.
The linux’sdefault security Settings relative to the Windows security many
The development
The development of Linux is one of the most prominent examples of free and open source software collaboration: the underlying source code may be used, modified, and distributed—commercially or non-commercially—by anyone under licenses such as the GNU General Public License. Typically Linux is packaged in a format known as a Linux distribution for desktop and server use. Some popular mainstream Linux distributions include Debianand its derivatives such as Ubuntu, Fedora and openSUSE. Linux distributions include the Linux kernel, supporting utilities and libraries and usually a large amount of application software to fulfill the distribution's intended use.
The uses.
The popularity of Linux on standard desktop computers and laptops has been increasing over the years. Currently most distributions include a graphical user environment, with the two most popular environments being (which can utilize additional such as the default and ), and the .
The linux is a leading operating system on servers and other big iron systems such as mainframe computers and supercomputers: more than 90% of today's 500 fastest supercomputers run some variant of Linux, including the 10 fastest. Linux also runs on embedded systems (devices where the operating system is typically built into the firmware and highly tailored to the system) such as mobile phones, tablet computers, network routers, televisions and video game consoles; the Android system in wide use on mobile devices is built on the Linux kernel.
The Linux market is growing rapidly, and the revenue of servers, desktops, and packaged software running Linux was expected to exceed $35.7 billion by 2008. According to the Linux Movies Group, more than 95% of the servers and desktops at large animation and visual effects companies use Linux.
That’s all!
Thank you!
