This article is written for people who have not been exposed to a Linux system. Understanding the Linux system is necessary for a technology (even if it is not directly related to the computer), but for the general user, only to understand Windows is enough, but to understand the Linux system I think it is useful (although it is difficult to immediately appear).


Let me take a quick look at the simple form of a question to show you what Linux is:


Q: Summarize Linux in a nutshell?

A:linux is an operating system, just like windows.

To learn about Linux, learn about the open source movement first. This was a campaign launched by Mr. Richard Stallman in the 80 's. The main goal is to create a complete computer system, all of which are open source. The initial purpose of the project is very good. In an interview with Stallman, "if the whole system is open, you don't have to be forced to cheat on your friends at some point," the GNU Project is for more justice, peace and fraternity.


Of course this is from a metaphysical point of view, from a metaphysical point of view, because members (tens of thousands of hackers) are out of interest free labor, all its achievements are free, the world is big to supercomputers, small to the router can run Linux system. Linux occupies more than 80% of the supercomputer, and the websites you visit, such as QQ, are basically Linux. The famous hundred-dollar computer program for children, using Linux as the operating system. China uses Linux exclusively in the so-called godson program.

What can q:linux do?

A: In addition to Linux, there is no game software, it seems to be no different from windows, if not the same, just more powerful.

Q: If I choose Linux, what will I get and what will I lose?

A: If you are a good learner, Linux is like a treasure trove. Because you can come into contact with the results of world-class hackers. If you're a less brain-loving person, Linux means less resource usage and can run the latest Linux systems even on very old computers. No virus, no antivirus software required. No longer need to install pirated windows, away from endless blue screens with trojans, viruses.


Linux software can be simply through a "software center" to download things, and do not need to look everywhere, there is a very appropriate analogy: With Linux is like the home to open a supermarket, want to go directly to the shelf to take it. Microsoft is learning now, so now there's something called Application Center in Windows8, but it's still less than Linux, because Linux is mostly free.


However, Windows software cannot be installed directly on Linux. While the relative software is almost always a substitute for Linux. If you want to run Windows software on Linux, you can use an adaptation layer called wine, but this stuff is complicated and not everything can be wine.


Second, because ActiveX is Microsoft's proprietary technology, the use of ActiveX places, such as most domestic banks, can not be used under Linux. But not all the net silver can not be used, and in the virtual machine to install a Windows dedicated to run online silver.

What is the compatibility between Q:linux and Windows?

A: If you're asking for file interoperability, 90% of files created under Windows can be opened under Linux and vice versa. But not all, because although I have not met, but it is said that there are similar cases.

Q: Does Linux need to be proficient in computers or does it require expertise?

A: I'm pretty sure the answer is "No" because what I've given my parents is Linux and what expertise they have. Now the Linux GUI has developed very well and is no different from windows. The difference is only used in the habit, such as Ubuntu default maximum Minimized button is on the left, and windows on the right, and you can no longer see the disgusting CDE drive letter.


I know people, no less than 10 people have said to me, the computer problem, to get a computer to go to the place to redo the system. I was very surprised, because as far as I know, redo the system outside seems to be 20-30 dollars, and I will be in the virtual machine in a few days to reload the system, no one has ever paid my money (laughter). If you have a problem, the only thing you can do is get someone to redo it, what's the difference between Windows and Linux?


It is important to note that if you take a Linux computer to find a sale, the only response they can do is to slam the door in front of you or reload a win for you, so you'd better have a knowledgeable person around you. But not necessarily, for example, I do not pretend, there is no problem.

Attached: Linux and Unix in the end what relationship?


Small series in many forums bar have seen a group of small white differences between Linux and Unix, and even some people think that Linux is a cottage Unix ... So small write down this article:


The biggest difference between Linux and UNIX is that Linux develops free software for source code, which is the traditional commercial software that protects the source code from intellectual property.


The source of Linux goes back to the oldest UNIX. Linux originates from the simple needs of a student. The only software that Linus Torvalds,linux's authors and major maintainers can afford when they go to college is Minix. Minix is a Unix-like simple operating system that is widely used to aid teaching. Linus to Minix not very satisfied, so decided to write their own software. He started his work on an Intel 386 PC as a prototype of the familiar UNIX of the student age. He was very quick and encouraged by his work, and he shared the results with other students through the Internet, mainly in the academic field. Someone saw the software and started distributing it. Whenever a new problem arises, someone will immediately find a solution and join it, and soon Linux becomes an operating system. It is worth noting that Linux does not include UNIX source code. It was rewritten in accordance with the open POSIX standard. Linux uses the GNU software from the Free Software Foundation of Cambridge, Massachusetts, and Linux itself is built with them.

Two other major differences:


1) UNIX systems are mostly hardware-compatible, while Linux can run on a variety of hardware platforms.


2) UNIX is a commercial software, and Linux is free software, free, open source code.


Unix's history is longer than Linux. Linux is thought to originate from Unix


Both UNIX and Linux are the name of the operating system. But the Unix four letters, in addition to the operating system name, also belong to SCO as a trademark.

Linux is commercialized with Redhat Linux, SuSe Linux, Slakeware Linux, red flags in the country, and Turbo Linux.

Unix is dominated by Sun's Solaris, IBM AIX, HP-UX, and the SCO Unix/unixware of the x86 platform.

Other differences:


The core of Linux is free, free to use, and the core source code is open. And the core of UNIX is not public.


On hardware requirements, Linux is lower than Unix and less demanding than UNIX. Linux is easier to master on installation than UNIX.


In use, Linux is relatively less complex than UNIX. UNIX is mostly hardware vendors for their own hardware platform of the operating system, mainly related to the CPU, such as Sun's Solaris as a commercial, positioning in its use of SPARC/SPARCII CPU workstations and servers, of course, Solaris also has x86 version, Linux also has its own version of RISC.


As for the price, the personal use of Linux is basically free, different Linux vendors for enterprise-class applications on the basic system of some optimizations, such as Redhat Enterprise products, these products including support services are more expensive.


UNIX, like Ibm/hp/sun, because it is primarily for its hardware platform, so the operating system is usually in the device price. (No one is going to buy a Unix operating system alone.)


In terms of performance, Linux is not as comprehensive as UNIX, but is largely more than enough for individual users and small applications. Typically, if you have access to a UNIX environment, such as the banking and telecommunications sectors, it is generally a fixed-model UNIX. For example, the majority of sun in telecommunications, civil aviation in the majority of HP, the majority of IBM in the bank. In learning, different UNIX command sets are somewhat different, so be aware of them. As for learning, I think Linux is more studious, and now like and tinker with Linux more and more people, a variety of information about Linux is also a lot. If you want to learn, then the Linux or BSD system is a good choice. A x86 machine will do.


Application, unless it is a large website, general enterprise or individual, use Linux. UNIX is a powerful, full-featured multi-user, multi-tasking operating system, can be applied from supercomputer to ordinary PC and many different platforms, is the most widely used, the most influential operating system.


Linux is an operating system that looks and performs the same or better than UNIX, but Linux does not originate from any version of Unix's source code, not UNIX, but a Unix-like product. Linux products successfully imitate the UNIX system and functions, specifically, Linux is a set of compatible with System V and BSD Unix operating systems, for System V, the current software program source code to Linux under the recompile can be run, and for the BSD UNIX, its executables can be run directly in the Linux environment.


In general, Linux is a set of operating systems that comply with the POSIX (Portable OS Environment) specification, which enables all UNIX features on an ordinary PC computer with multitasking and multiuser capabilities. Another major reason for Linux's fondness for computer enthusiasts is that it has the full functionality of Unix, and anyone who uses UNIX operating systems or who wants to learn UNIX operating systems can benefit from Linux.


In terms of network management capabilities and security, people who have used Linux agree that Linux is similar to UNIX. UNIX system has been used as a high-end application or server system, so has a set of perfect network management mechanism and rules, Linux followed these excellent rules, so that the network can be configured very strong, providing a great flexibility for system management.
