But for Linux, this only numerous news one of. Rece ntly, the manufacturers concerned have announced that support the news of Linux to i ncrease day by day, users' enthusiasm to Linux runs high unprecedentedly too. Then, Linux only have operating system not free more than on earth on 7 year this piece wh at glamour, get the favors of such numerous important software and hardware manufa cturers as the masses of users and Orac le , Informix , HP , Sybase , Corel , Intel , Net scape , Dell ,etc. , OK?1.The background of Linux and characteristicLinux is a kind of " free (Free ) software ": What is called free, mean users can o btain the procedure and source code freely , and can use them freely , including revise or copy etc.. It is a result of cybertimes, numerous technical staff finish its research a nd development together through Inte rnet, countless user is it test and except fault , c an add user expansion function that oneself make conveniently to participate in. As the most outstanding one in free software, Linux has characteristic of the following:(1)Totally follow POSLX standard, expand the network operating system of sup porting all AT&T and BSD Unix characteristic. Because of inheritting Unix outstandi ng design philosophy , and there are clean , stalwart , high-efficient and steady kernels , their all key codes are finished by Li nus Torvalds and other outstanding programmer s, without any Unix code of AT&T or Berkeley, so Linu x is not Unix, but Linux and Unix are totally compatible. (2)Real many tasks, multi-user's system, the built-in n etwork supports, can be with such seamless links as NetWare , Windows NT , OS/2 , Unix ,etc.. Network in various kinds of Unix it tests to be fastest in comparing and ass ess efficiency. Support such many kinds of files systems as FAT16 , FAT32 , NTFS , E x t2FS , ISO9600 ,etc. at the same time .(3) Can operate it in many kinds of hardwares platform , including such processo rs as Alpha , SunSparc , PowerPC , MIPS ,etc., to various kinds of new-type periphera l hardwares, can from distribute on global numerous programmer there getting suppor t rapidly too.(4) To that the hardware requires lower, can obtain very good performance on mo re low-grade machine , what deserves particular mention is Linux outstanding stability , permitted " year " count often its running times.2.Main application of Linux At present,Now, the application of Linux mainly includes:(1) Internet/Intranet: This is one that Linux was used most at present, it can offer andinclude Web server , all such Inter net services as Ftp server , Gopher server , SM TP/POP3 mail server , Proxy/Cache server , DNS server ,etc.. Linux kernel supports I Palias , PPP and IPtunneling, these functions can be used for setting up fictitious host computer , fictitious service , VPN (fictitious special-purpose network ) ,etc.. Operatin g Apache Web server on Linux mainly, the occupation rate of market in 1998 is 49%, far exceeds the sum of such several big companies as Microsoft , Netscape ,etc..(2) Because Linux has outstanding networking ability , it can be usedin calculati ngdistributedly large-scaly, for instance cartoon making , scientific caculation , database and file server ,etc..(3) As realization that is can under low platform fullness of Unix that operate , ap ply at all levels teaching and research work of universities and colleges extensively, if Mexico government announce middle and primary schools in the whole country dispo se Linux and offer Internet service for student already.(4) Tabletop and handling official business appliedly. Application number of peo ple of in this respect at present not so good as Windows of Microsoft far also, reason i ts lie in Lin ux quantity , desk-top of application software not so good as Windows ap plication far not merely, because the characteristic of the freedom software makes it n ot almost have advertisement that support (though the function of Star Office is not second to MS Office at the same time, but there are actually few people knowing).3.Can Linux become a kind of major operating system?In the face of the pressure of coming from users that is strengthened day by day, more and more commercial companies transplant its application to Linux platform, co mparatively important i ncident was as follows, in 1998.(1)Compaq and HP determine to put forward user of requirement truss up Linux at their servers , IBM and Dell promise to offer customized Linux system to user too.(2)Lotus announce, Notes the next edition include one special-purpose edition in Linux.(3)Corel Company transplants its famous WordPerfect to on Linux, and free issue. Corel also plans to move the other figure pattern process products to Linux platfor m completely.(4)Main database producer: Sybase , Informix , Oracle , CA , IBM have already been transplanted one's own database products to on Linux, or has finished Beta editio n, among them Oracle and Informix also offer technical support to their products.4.The gratifying one is, some farsighted domestic corporations have begun to try hard to change this kind of current situation already. Stone Co. not long ago is it inves t a huge sum of money to claim , regard Linux as platform develop a Internet/Intranet solution, regard this as the core and launch Stone's system integration business , plan t o set up nationwide Linux technical support organization at the same time , take the le ad to promote the freedom software application and development in China. In additio n domestic computer Company , person who win of China , devoted to Linux relevant software and hardware application of system popularize too. Is it to intensification th at Linux know , will have more and more enterprises accede to the ranks that Linux w ill be used with domestic every enterprise to believe, more software will be planted in Linux platform. Meanwhile, the domestic university should regard Linux as the origin al version and upgrade already existing Unix content of courses , start with analysing t he source code and revising the kernel and train a large number of senior Linux talent s, improve our country's own operating system. Having only really grasped the operati ng system, the software industry of our country could be got rid of and aped sedulously at present, the passive state led by the nose by others, create conditions for revitalizi ng the software industry of our country fundamentally.。
