In August 1991, a student in Finland sticked the following paragraphs in the Comp.os.minix newsgroup: "Hello, all people who use minix - I am doing a free operating system for 386 (486) AT ( Just to hobbies), it will not be very professional as GNU. "This student is Linus Torvalds, and what he said" hobby "will become Linux you know today. As a similar POSIX-like operating system with all characteristics, Linux is not only developed by Linus, but is developed by hundreds of programmen around the world. Interesting is that this huge development of the world is not very coordinated. Of course, Linus has set a step in the core, but Linux is not just the core. There is no management organization; a Russian student gets a new motherboard and writes the drive program to support this host board. A system administrator in Malan needs a backup software, write one and pass it to anyone you need. It seems to always happen the right thing. Another interesting thing is that you will get Linux without spending money. As long as you have time and willing to download, you can get most software for free. But not everyone has time ... Domestic newspaper has slowly emerged more and more Linux related reports, in the United States, "Linux phenomenon" has also caused a craze discussion, but I believe most people in China have linux. Maybe still is very unfamiliar, about many people have "what is Linux?", In fact, Linux is not surprising, simple, Linux is a unix-like operating system, a Unix It controls the core program of the basic service of the entire system, which is developed by Finnish Linus Torvalds, "Linux" name is named "Linus's Unix". In 1991, it was still a college LINUS to publish the original code of Linux core on the Internet, and select "Volkswagen Public Copyright (GPL)" to issue this program, this copyright allows anyone to scattered with any form The original program of Linux, the increasing number of Internet networks and the copyright of Linux open free, attracts countless computer masters to develop, improve the core of Linux, so that Linux's functionality is strong. In addition to the core program, one work system also requires other system programs to have practicality, and most of the system-programs commonly used in Linux systems are software developed by Free Software Foundation, and there are also Many institutions or individuals use their own ourselves, and they do not have to develop applications for Linux. These programs are most free software, and anyone can get free on the Internet. However, it is very inconvenient to make it to get these programs, so there are some companies with system integration capabilities to collect, integrate Linux, and put "core-system program-application" always form a complete The operating system allows general users to install intact systems, which is called "Distribution".
We generally speak Linux systems For these installation kits, the Linux installation kit has a wide variety of Slackware suits that have been very popular in Taiwan, and more and more people have used Debian. Redhat Linux with more than half, these different installation kits are a Linux system, and they also use Linux cores. The programs are similar, and the programs are shared. Different places are only in some system settings and program kits. The management method is more. It is also a Linux system, which is divided into different installation kits that are integrated with different companies, institutions, which is the reason that everyone often sees Linux on the Internet. Linux has a UNIX system program interface with an operation mode, which also inherits UNIX stable and efficient characteristics. The mainframes installed on the Internet have been continuously transported for more than a year, and it is not necessary to shut down is a generous thing, but linux but but Unlike general UNIX, you must use a huge copyright fee, and you can use it on exclusive expensive hardware. Linux can perform on the general I386 PC, naturally receive the program resource and user accumulated on UNIX in the past few decades, plus the GPL copyright allows you to spread the original code of Linux free, and modify your own demand The program makes Linux have become a very popular multi-worker, free, stable, high efficiency, can be implemented on many different computer system platforms including I386, SPARC, Alpha, MIPS, PPC ... system. Provide Chinese Chemical Easy "Console", MIS can easily set Email account, DNS, proxy, ... and other parameters through the web Chinese screen. Linux features basically Linux is "free", you can freely upload download from the Internet. However, due to the least hundreds of MBs of the LINUX even their affiliates, most people will purchase their CD-ROM for free. Its CD-ROM is generally from one hundred yuan to thousands of dollars. Linux is much cheap than other OS, and has become the preferred by many students and small companies. Many people only pay attention to Linux does not have money, but it is more important than free, Linux is a free software. The freew in English is actually explained as "freedom" rather than "free" in some Chinese translation documents. As a free software, anyone can freely modify or linux Source Code to others. For experienced engineers, he can legally modify Linux to meet yourself. For students, reading Linux Source Code can understand the internal operation of the operating system and the programming skills of learning masters, and improve personal abilities. Others can have improved results for the system free or with low cost. Plus Linux uses "(Bazaar) development model, welcome anyone to participate in its development and correction work, attracting a large number of Hacker and computer enthusiasts to use and send back their own improvement or research and development. It is the so-called three stinklers, better than Zhuge Liang, which makes the debug and revision of the revision, stability and high stability and efficiency. This is also the main reason why Linux has developed faster than other os (such as FreeBSD).
