Shuimu - give Linux newbie [series 2]
OK, your first question is: What is Linux, what is the difference between it and UNIX? Asking this question, most of you are still going to the laboratory when you are still in the big one, seeing a high-end student on a large-scale screen, you envy him, ask: "What is this computer?" Ah, so advanced? "And he didn't rather say," This is Unix ". Later, you know more, know that is a Sun workstation, running Solaris above, is UNIX. Now you have heard that Linux is also unix, what is going on? Short Answer: Going to read, many Linux books on the street is to talk about their history and relatives. Long Answer: Unix is a 20 or 30 years ago by several graduate students starting a large company to commercialize it. One go on two, it grows and occupies the market. At that time, it was only running on only university to buy one or two expensive machines. Later, there were more machines, the company is more, knowing more people, I will share it, and "UNIX" is due to legal relationships, no one can say that their operating system is "UNIX" and can only say "Unix compatible" The system. So now the "UNIX" system does not exist, existed is just a distant legend. So what are you Solaris, AIX, and IRIS now? All companies are commercial Unix on their hardware. These systems follow a quirky standard called POSIX, right, this standard, it is too many unstead of Unix, everyone's programming interface or even orders are different. So there is no way to discuss an agreement. So what is linux? Linux is a UNIX compatible system based on PC (other platforms), which is not far from any other UNIX compatible system with UNIX. So if you have "Solaris is orthodox UNIX, Linux is just compatible" ideas, I am not wrong, at least you have to defeat the people who support AIX, they also think that AIX is orthodox UNIX. So using Linux you can learn about UNIX, which most of which can be used on other commercial UNIX. Of course, its core ideas are definitely the same. So only three years ago, only your doctor's counselor has the opportunity to learn in the laboratory, you can practice on the PC now. Is this not a very wonderful thing? Second question: I want to install a Linux, which version, I have heard XXXLinux, YYYLINUX, and there is also a strong ZZZLinux that has been promoted in China. Which one is better? First of all, you need to understand that Linux is not Windows, it is not a software maintained by a commercial company, only one packaging. Linux is something that can be configured freely. Any person, a company can follow his own ideas, such as adding a point, plus Chinese support, making a Linux coming out. These Linux although the core part is the same, the various software they have, are different from the default configuration. The difference is to use a Linux release (different Linux, we are called different releases) may have a good hardware, and various software is also installed. It is also possible to support Chinese with another kind of software. In short, there is no white-eating lunch. Of course, you will need you to stay up until you stay in Linux.
