Lesson 1: What is Linux
Simply put, Linux is a free use and freely propagated UNIX operating system, which is mainly used on a computer based on Intel X86 Series CPU. This system is designed and implemented by thousands of programmers around the world. Its purpose is to establish a copyright restriction that is not subject to any commercial software, and the world can freely use UNIX compatible products.
The emergence of Linux, the earliest start in a computer hobby called Linus Torvalds, at the time he was a student at the University of Helsinki, Finland. His purpose is to design an operating system that replaces Minix (is a handling system named Andrew Tannebaum), this operating system can be used for personal computers of 386, 486 or Pentium processor And with all the functions of the UNIX operating system, therefore started the design of the Linux prototype.
Linux is known for its efficiency and flexibility. It enables all UNIX features on the PC computer, with multiple tasks, multi-user capabilities. Linux is free for GNU public licensed permissions and is a POSIX standard operating system. The Linux operating system software package includes not only a complete Linux operating system, but also application software such as text editor, advanced language compiler. It also includes a x-windows graphical user interface with multiple window managers, just like we use Windows NT, allow us to operate using windows, icons, and menus.
The reason why Linux is loved by the majority of computer enthusiasts, one is two, one is that it belongs to free software, users can get it and its source code without paying any fees, and can be necessary according to their own needs Modify, useless to use it, continuing to spread unconfiling. Another reason is that it has all functions of UNIX, anyone who uses a UNIX operating system or wants to learn a UNIX operating system can benefit from Linux.
Second lesson: Why use Linux?
Since Linux is a free operating system with UNIX full-feature, it has a great advantage in many software, providing learning, exploring, and modifying computer operating system kernels for the majority of computer enthusiasts. The operating system is an indispensable system software that is the soul of the entire computer system. An operating system is a complex computer assembly that provides an agreement or behavioral criterion for the operation process. Without operating systems, the computer cannot work, you cannot explain and perform user input commands or run simple programs. Most operating systems are commercial procedures supported by some major software companies, and users can only be used. If the user purchases an operating system, he must meet all the conditions required by the supplier. Because the operating system is a system program, the user cannot modify or test the kernel of the operating system without authorization. This is undoubtedly a constraint for the majority of computer enthusiasts.
To play the role of your computer, only the operating system is not enough, users must have support for various applications. The application is a package for handling certain work (such as word processing), usually it can only be used. Each application's package is written for a specific operating system and machine. Users have no right to modify these applications. With Linux, the operating system can be used as an operating environment.
Since Linux is a free software, the user can get it and its source code without paying a large number of applications without compensation, and can be arbitrarily modified and supplemented. This is very beneficial for users to learn, understand the kernel of the UNIX operating system. Learning and using Linux, can save users a considerable funds. Linux is currently available free of charge, providing multiple tasks, multi-functional operating systems on the PC platform, which is the main reason for people to use it. For the PC platform, Linux provides power than any other operating system. Linux also allows users to stay away from various commodity software providers to promote advertisements, and no need to withstand it every time. Bitter, so you can save a lot of funds for purchase or upgrading applications. Linux not only provides users with powerful operating system features, but also provides a wealth of application software. Users can not only download Linux and their source code from the Internet, but also download a number of Linux applications from the INTERNET. It can be said that Linux itself includes applications that are ported to Linux, and any user can find applications and their source code that suits them from the Linux website, so that users can You need to download source code in order to modify and expand the functionality of the operating system or application. This cannot be done for the commercial operating system such as Windows NT, Windows98, MS-DOS or OS / 2.
Linux provides a major opportunity to learn and use the UNIX operating system at home. Although Linux is developed by computer enthusiasts, it is quite stable in many ways, so that users learn and use the current most popular Unix operating system in the world. Opportunities. There are now many CD-ROM vendors and software companies (such as Redhat and Turbolinux) support Linux operating systems. Linux has become a substitute for UNIX systems on a personal computer and can be used to replace those relatively expensive systems. Therefore, if a user is programmed on UNIX system when you go to work, or a UNIX system administrator, he can install a UNIX compatible system at home, the Linux system, using Linux at home. You can complete some work tasks.
