Then, Linux only have operating system not free more than on earth on 7 year this piece what glamour, get the favors of such numerous importa

3、nt software and hardware manufacturers as the masses of users and Orac le , Informix , HP , Sybase , Corel , Intel , Netscape , Dell ,etc. , OK? 1.The background of Linux and characteristic Linux is a kind of free (Free ) software : What is called free, mean users can obtain the procedure and source

4、 code freely , and can use them freely , including revise or copy etc. It is a result of cybertimes, numerous technical staff finish its research and development together through Inte rnet, countless user is it test and except fault , can add user expansion function that oneself make conveniently to
