Linux is a core site of Linux that is related to Linux, which is based on the development of Linux's core version of the GNU program Linux Mathew Stallman GPL , which relates Issued by several important software Linux distributions Publisher URL = w=

1. What is Linux?

• We know that computers are made up of a bunch of hardware.
• In order to effectively control these hardware resources, there is an operating system
• To make it easier for software developers to develop, the operating system provides developers with a range of interfaces
• Linux is a set of operating systems with core and system call functions! The application is above the two tiers.

2, from the operating system and CPU architecture related to Linux

• We know that the architectures of various CPUs are different!
• The architecture of the CPU determines the operating system that can operate on it, that is, window is usually not installed on the MAC because the CPU architecture is different! In layman's words, Windows is not able to run on a washing machine hardware anyway? Every operating system is running on his dedicated machine!
• The operating system itself is for the user needs of the "hardware architecture" to design, mobile phone corresponding to Android and other mobile phone operating systems, computers corresponding to Windows and other computer operating systems, which are hardware-related.
• This is the reason why you should speak so much hardware when talking about Linux.

• Linux is an Open Source operating system, so his program code can be modified to fit about in each machine , which means that Linux is "displaced", which is important function Oh! ^_^

• Since this excellent operating system can now run on the x86 architecture system (also known as the most common personal computer), many developers are turning to Linux, so there is no shortage of common application software on Linux.

3. Why is Linux a very stable operating system?

4. From Richard Mathew Stallman to Linux

• In the beginning, a variety of software, operating systems are all commercial companies, commercial disputes, patents are a lot of trouble.

• In 1984, Hoot Tommen began the GNU (GNU's not unix!) program, which was intended to create a free, open UNIX operating system.

• Clever Hoot Tommen simply counter his way and line ~ "Since the operating system is too complex, I will first write can be run on Unix on the small Asmeamerican order, this is always OK?" "In this idea, Hoot Tommen began to refer to the existing software on Unix , shipowner based on the role of these software to develop the same software, in the development period Stallman never look at other software source code, to avoid the case of grams. Then a bunch of people know that the free GNU software, and the actual use found with the original patent software is not too much, so instead of using GNU software, and is the GNU program to gradually open up awareness

• Although the GNU program has gradually opened its profile, visibility is still not enough. At this time Hoot Tommen and thought: "Do not ask is what the software, all have to import line compiled into things import file (binary program) to be able to execute, if you can write a wrong compile Asmeamerican order, that is not everyone needs software?" So he began to write the C compiler Asmeamerican sequence, which is now quite famous GNU C Compiler (GCC)!

• The GNU project has inspired many young hackers who have written a lot of free software. Finally, Linus Torvalds wrote a Unix-like operating system called Linux, which connects all GNU software and hardware, but Linux does not represent the entire operating system, Linux is just a kernel, and the entire system contains hundreds of software tools and utilities. Most of them are done by GNU hackers. He thinks that the whole operating system is called gnu/linux more appropriate. The Linux kernel draws a full stop for the GNU project.
• In addition, he has written more jutting C function libraries (GNU C library), as well as the basic interface that can be used to operate the operating system BASH Shell! All of this was done in the 1990 left history!

5, in order to avoid the free software developed by the GNU to be used by others to become the software with Lee, so Richard did not counsel drafted a common public License (general publicly License, GPL), shipowner hideaway called him copyleft (relative II and Lee software copyright! )。

6. GNU has developed several important software, such as:? Emacs? GNU C (GCC)? GNU C Library (glibc)? Bash Shell causes many software developers to develop their programs from these basic tools!
