What is Linux

Computer mainly in binary units, and the current commonly used disk capacity unit B, its units converted to 1b=8bit, the other 1024 for its multiples, such as 1GB=1024MB.

The operating system (operation system) is primarily used to manage and drive hardware, so you must be able to manage memory, manage devices, manage process management, and system calls. So, as long as you can get the hardware ready, it's a great operating system.

Operating system focus only on the driver and management of hardware, and to use hardware, you need to through the application software or shell functions, to invoke the operating system to manipulate hardware work. Therefore, the current operating system in addition to the above functions, usually contains the daily work required by the application software within.

UNIX, formerly known as the Bell Lab, was written in assembly language by Ken Thompson of Bell Labs, and later in 1971-1973, it was rewritten by Dennis Ritchie in C programming language, called UNIX.

1977 by Bill Joy released BSD (Berkeley software distribution), these are called Unix-like operating systems.

The Minux operating system was produced by Andrew Tannenbaum in 1984, which provides source code and software.

In 1984, the GNU Project was advocated by Richard Stallman, which advocates free software, emphasizing that its software is free to acquire, reproduce, modify and redistribute, and to standardize the GPL licensing model, any GPL License) software should not only sell its software, nor personalized software licensing.

The Linux operating system was developed by the Finnish Linus Torvalds in 1991. In short, Liunx's success lies primarily in the creation of Minux (UNIX), GNU, Internet, POSIX, and virtual teams.

Linux itself is a great operating system, its development site is set up in http://www.kernel.org, we call the Linux operating system at the bottom of the data is "kernel" (kernel).

At present, the development of the Linux kernel is divided into two versions, the stable version of the even version, such as 2.6.x, suitable for commercial and domestic use, one is the development of the version, such as the 2.5.x version, suitable for the development of special functions of the environment.

Linux distributions is a complete set of systems made of "Linux Kernel+free software+documentations (Tools) + fully-installed programs".
