Talk about Dos and UNIX.

Let me tell you something about me and the modern operating system. Before yesterday, in fact, I and most of you are basically a layman, small rookie, Oh! ~ ~ ~ Well, now is a small rookie, hey! The computer may be with you more time than I can, or less than me. Remember very small time, I do not remember the specific time, anyway, when I came into contact with the computer when the system is basically installed Windows 98 or ten, Windows Me I did not see, I feel and my age (22 years) of the young people should be more than I touch the computer early, My home is our village the first to buy a computer, in fact, to buy a computer my father to fry, but later also did not fry, but became I and brother's game machine, basically most people and I just like it, in the beginning of contact with the computer is to play the game bar. Many of you should know that when the computer interface icon is the big one, the color looks monotonous, but it does not affect our enthusiasm for it. I have witnessed its development, it has been accompanying me to the present, I feel that I can not leave it, you are probably similar to me.

See this article you probably also like me is a programmer, since it accompanies us so, we are this professional, should have a very detailed understanding of it. Just as we began to learn Chinese characters, we began to learn from phonetic alphabet. Pull enough, say that everyone should be in the mind will scold me, hey, joking ~ ~ Then I will give you to talk about Dos and UNIX those things, said not good everyone do not hit me.

First of all to tell you about DOS, why say it? There must be a reason, it is the root of the operating system Ah, must say. What is a DOS operating system? DOS is actually a short name for disk operation system (diskette OS). As the name implies, this is a disk-based management operating system. The biggest difference with the operating system we are using now is that it is in the command line form, by the input command to the man-machine dialogue, and through the form of command to the computer, let the computer realize the operation. This people should be very familiar with, basically used.

About DOS In fact there is a very interesting story, probably most people do not know that it is not actually created by Microsoft, Microsoft began its own operating system called MS-DOS, but a call Gari Kirdell (Gary kildall) invented, there is no way to let someone else Microsoft strength, have the power to have the right to speak That's not nice. Bill Gates is a thief, money is talking, it can write history, money has hands, it can rewrite history. Kildare's friends and admirers said: "Every PC user owes Kildare a share, and Bill Gates and his Microsoft company owe more than anyone else." "Just as Gates is treating his own leader, Roberts, to cover up his" debt ", Mr Gates's approach is to downplay the Kildare and set up another DOS father to squeeze him out of history! Malls such as battlefield, in which I do not comment more. About Gary Kildall's story everyone has the time, I recommend everyone to see, he brought to the PC industry's contribution is huge.

Microsoft has built the cornerstone of its BR in the PC World by DOS. Windows system up to now almost 20 versions of it, mainly to tell you about the most important bar, Windows has two branches, one is the Windows family, one is based on the Windows NT (new technology) series. Windows 1.0 was the first attempt by Microsoft to make a graphical user interface for the PC operating platform. Windows 1.0 essentially declares the end of the MS-DOS operating system (command line interface), and continues to the later version of Windows 3.0, Microsoft has made improvements to the interface, memory management, and also added CD audio players on the basis of 1.0. Until Windows 95 was released to the operating system for another big change, Windows 95 was released with a powerful offensive, including the commercial nature of the Rolling Stones song "Start Me Up". Many customers without computers have been lined up to buy software, but they don't even know what Windows 95 is, and the release of Windows 95 lays the dominant position of Microsoft in the GUI market and shows how influential the 95 version is. Since the 95 version of the emergence of a succession of like 98, XP, 7,win 8, until now WIN10

The later versions of the people know more than I will not wordy.

Because of the reason for using Windows operating system computers from a small age, there is a unique feeling about windows. But until then I learned from the learning process slowly to the software industry has a further understanding I only know that in addition to Microsoft's operating system and our normal personal computers do not use the UNIX and other Unix-like operating systems, I understand that I was sit idle, I believe that many people and my situation is similar, do not agree with me when I did not say. So OK, nonsense not much to say, hurriedly everyone to chat.

In fact, I contact Unix time is not very long, the understanding of it is not too detailed, I later installed the system is similar to its Linux system, I believe everyone has heard. Although the time to contact it is not long, but it has attracted me deeply, let me have to make a sigh, this is the programmer should use the system. In fact, most schools in foreign countries teach UNIX, although Windows accounts for the vast majority.

UNIX's predecessor was Multics (Multics, an operating system project operated by MIT, T Bell Labs and GE, was designed to run on the GE-645 mainframe, but because the whole goal was too large to blend too many features, Although Multics released a number of products, but the performance is very low, and at the end of the Multics project to withdraw resources, stop the cooperation project, Ken Thompson and Dennis Ritchie on the Multics based on the creation of the earliest version of UNIX, At that time, actually not called Unix,unix is later changed the name. Here I would mention that the C language we studied was invented by both of them in 1971. Later with the UNIX users, Unix began to charge, what a charge ah, so many people will create and its similar things, it seems to be our natural nature, charge a lot of people will not be willing to ah, and then appeared later many Unix-based operating systems, POSIX as a standard (there is no standard that is not a mess), unified call them unix-like, from the literal meaning of everyone can understand, is the Unix-like system. The best of them I think is the Linux system.

So the question is, who created Linux? That is the subversion of the world's "liberal pope" Linus, Torvalds, first of all to affirm that the previous title is given, not my one-sided words. From that you can see Linus, Torvalds on the Linux status. Citing a paragraph of Linus, Torvalds said in a response to a Microsoft Senior vice President Craig Mundie's comments about the open source movement (Mundie criticized the open source campaign for destroying intellectual property), Torvalds wrote: "I don't know if Mundie has heard of Isaac Newton ( ISAAC Newton) sir? Not only was he famous for his creation of classical physics (and the story of him and Apple), but he was also famous for saying such a word: I was able to see farther, because I stood on the shoulders of giants. Torvalds said, "I would rather listen to Newton than listen to Mundie." He (Newton) died for nearly 300 years, but did not make the room so smelly. "Formally because Torvalds insists on the open source belief, it makes the Linux development more and more good."

It is because of the Linus, Torvalds this open-source spirit, let me have an incomparable awe of it.

If everyone has a grudge against Microsoft's Dos and UNIX, the interesting story that happens between them is that you can go to this site to see http://news.mydrivers.com/1/320/320136.htm. I think it's very interesting.

It's not too early to get here, we'll talk later.
