Weak current College】 【introduction to the Linux operating system.

<br> <br> First, the origin, characteristics and Linux applications <br> <br> The earliest Linux operating system kernel is Finland's LinusTorvalds1991 August in Helsinki University School publication [that year-old Torvals25], and later through many of the .world's top software engineers constantly modified and perfected, Linux to global popularity, in the server field and personal Desktop Edition get more and more applications, more in embedded development with unparalleled advantage in other operating systems, and to each of the 100% the number of .users increase shows Linux powerful force. <br> <br> Linux is a free 32-bit many more workers operating system, run in the same way like a UNIX system, but Linux system stability, retasking capability and network function has many commercial operating .systems are incomparable, Linux is also the biggest feature is completely open source code, subject to the GNUGPL (GeneralPublicLicense), no person shall be free to access, distribute, or modify the source code. <br> <br> Compared with other operating .systems, Linux also has the following characteristics: <br> <br> ① use threaded directory structure, file collation clearly, easy management <br> <br> ② supports multiple file systems, such as Ext2FS, ISOFS and Windows file system FAT16, .FAT32, NTFS etc. <br> <br> Û portability, the system core only less than 10% of the source code uses written in Assembly language, and the rest are prepared using the c language, highly portable <br> <br> .④ with other operating systems such as Windows98/2000/XP, and coexist on the same computer <br> <br> Second, the mainstream introduction to Linux OS release <br> <br> On the nature of Linux, it is the core .of the operating system and is responsible for the control of the hardware, management, file system, processes, etc. LinuxKernel (kernel) is not responsible for providing the user a powerful application that does not have a compiler, system administration tools, network tools ., Office suite, multimedia, graphics software, the system was unable to play its powerful functions, users cannot use this system work, therefore it is proposed to further integration with the core LinuxKernel with various system programs or utilities that make up a complete operating system ., after such combinations of Linux that is known as a Linux distribution. <br> <br> Foreign package to RedHat Linux (also known as the "Red Hat Linux"), OpenLinux, SuSE, TurboLinux and most successful: <br> < .br> RedHat is a commercial atmosphere quite keen company, not only show a Linux commercial software attempting, in 1999 in the United States technology stocks-NASDAQ stock was listed on the company, RedHat Linux gradually been arch to the business leader. <br> .<br> <br> RedHat is currently the highest sales, install the most convenient, most suitable for the beginner Linux distributions, is the world's most popular Linux distribution, marketing, packaging and service do quite well, developed the RPM package manager and the .X desktop environment Gnome's numerous software and its source code back to OpenSourcecommunity. <br> <br> Also it is for the convenience of RedHat, Setup system architecture or software installation all made packaging, users learn the GUI interface (GUI) to enter some .superficial knowledge of setting a value, as for the software installed on those files, install directory, into which the file system for which settings to use with the unknown, once really experiencing system procedures when problems occur, to address the problem more difficult. < .br> <br> Caldera OpenLinux this system will be as easy to use and set release, to integrate the use of environmental and end-user Office environment, easy installation and simple management objectives for system, is expected to become the most popular corporate desktop .Linux operating system, suitable for the beginner to use, all installation requires 1 GB of hard drive space. <br> <br> Caldera has researched the graphical interface of the Setup Wizard, the installation process can play Russia square, providing a full KDE .desktop environment, with powerful commercial software, such as StarOffice, graphical interface for hard drive partitioning tool such as PartitionMagic. <br> <br> SuSE is Europe's most popular Linux distributions, and SuSE is a pioneer in software internationalization, software to support national .language, the contribution of drywall, SuSE RPM is also used as the software installation and management program, but are not suitable for novice SuSE use, provides very many tools software, all installation needs 4.5GB hard disk space, the installation process is also more .complex. <br> <br> TurboLinux is a Japan-made Linux release, its greatest features is in Japanese, Chinese traditional version of Jane /, the English version of the release of three forms, software internationalization promotion experience, ease of installation and .system settings for difficult and RedHat almost, and the installation interface is finished, the system itself supports Chinese simplified, China has a large user base. <br> <br> Domestic Linux distributions do relatively successful is a red flag and soft versions, the .interface is very beautiful, installation easier, the new version has a number of underlying shielded, suitable for novice users. Two versions are both derived from CAs's State 863 plan Linux project, but stability and compatibility compared with foreign versions haveA gap, interface and habits .and Windows and more like, providing technical support and after-sales service, suitable for domestic price of operating system solutions. <br>.
