What are the types of operating systems and what are their characteristics？

　　When it comes to mainstream operating systems, the first reaction of many friends should be windows XP and win7. Yes, but this is only a part of the computer windows operating system. What are the types and characteristics of mobile phone operating systems? The following small series will take computers and mobile phones as examples to talk about the types of operating systems and their characteristics.

　　1. What are the types of computer operating systems?

　　1、DOS — — Ancient overlord of operating system

　　DOS seems to be only the old birds have had contact with it now, and the new computer learners only have a little knowledge of DOS. It once occupied most of the field of personal computer operating system, and it can be seen on most computers in the world. Because DOS system does not need a very strong hardware system to support it, it can be used from business users to home users. Although it is not an excellent operating system at present, the characteristics of Microsoft software backwards compatibility determine that when something goes wrong with Windows, it often needs to be solved under DOS, so it is necessary to understand and learn DOS.

　　2、Windows — — Contemporary tycoon of operating system

　　Since Microsoft introduced Windows 1.0 in 1985, the Windows system has experienced more than ten years of ups and downs. From Windows 3.x, which originally ran under DOS, to Windows 9x and Windows 2000, which are now popular all over the world, Windows has almost replaced the position that DOS once took, and has become a new operating system tycoon. Its popularity does not need to be small.

　　3、Linux — — Seductive little penguin

　　Linux is a dazzling name in today’s computer world. It is the largest free and free software in the world. It is an operating system with comparable functions to Unix and Windows, and has complete network functions. Its usage is very similar to UNIX, so many users no longer buy expensive UNIX, but instead invest in free systems such as Linux.

　　Linux was originally developed by Finnish Linus Torvalds, and its source program was publicly released on the Internet, which aroused the enthusiasm of computer enthusiasts all over the world. Many people downloaded the source program and perfected a certain function according to their own wishes, and then sent it back to the Internet. Therefore, Linux was carved into the most stable and promising operating system in the world. Someone once joked that if Bill Gates did the same to the source code of Windows, many bugs (errors) left in Windows would no longer exist, because computer enthusiasts all over the world would become voluntary testers and programmers of Windows.

　　4、FreeBSD — — Magical spirit

　　FreeBSD is a Unix-like system running on x86 platform. It is marked by a mythical elf, developed from BSD Unix system, and written by Berkeley School in California. The first version was officially launched in 1993. BSD Unix and Unix System V are the two main streams of Unix operating system, and Unix systems in the future are derivatives of these two systems. This operating system is mainly used in the network server, which is not suitable for individual users.

　　5. NetWare system

　　Netware is a network operating system introduced by NOVELL Company. The most important feature of Netware is the open system structure based on the basic module design idea. Netware is an open network server platform, which can be easily extended. Netware system provides consistent services for different working platforms (such as D0S, 0S/2, Macintosh, etc.), different network protocol environments such as TCP/IP and various workstation operating systems. Optional extension services (such as backup backup, database, e-mail and bookkeeping) can be added to the system, which can be taken from Netware itself or from third-party developers.

　　6. Unix system

　　UNIX operating system is an operating system run on PDP-11 by American AT&T Company in 1971. It has the characteristics of multi-user and multi-task, and supports multiple processor architectures. It was first developed by ken thompson, dennis ritchie and Douglas McIlroy in Bell Laboratories of AT&T in 1969.

　　7. Mac OS system

　　Mac OS operating system is the first generation of operating system designed by Apple Computer Company for its Macintosh computer. This model was introduced in 1984. At that time, when the PC was just a boring character interface of DOS, Mac took the lead in adopting some technologies that we still praise. For example: GUI graphical user interface, multimedia application, mouse, etc. Macintosh computers are widely used in publishing, printing, film and television production and education, and Microsoft Windows still has the shadow of Mac in many aspects. Recently, Apple released the most advanced personal computer operating system, MAC OS X..

　　Second, what are the types of mobile phone operating systems?

　　1. Symbiain operating system

　　It includes Symbian UIQ, S40, S60 2nd, S60 3nd, s60 5nd, S80, S90, among which S40 is a Nokia-specific non-intelligent system, which is often listed because of Nokia’s high coverage. The development of UIQ system has stopped now, and S80 and S90 are only used on a few previous models, such as the high-end 9 series and 7710 mobile phones, and they have not been seen for a long time now.

　　At present, S60 systems that are mainly common in the market or mainly covered by mobile phone clients are developed, including the second and third editions, and these editions will also include FP1 and FP2. At present, Nokia, Samsung, Ximenzi, SonyErrison(UIQ system) and so on are more common mobile phones using Symbian system.

　　2. Windows Mobile operating system

　　If I understand correctly, the predecessor of Windows Mobile is PocketPC, SmartPhone and other series, and now it is unified into Windows Mobile.

　　There are different versions of this series, but like windows, it is basically from backwards compatibility. Unlike Nokia’s operating system, there are great differences between different versions.

　　3. Windows CE operating system

　　Domestic Coolpad and Meizu M8 all adopt Windows CE system, and Windows CE system is relatively more customized, but the current market coverage is small.

　　4. Iphone OS operating system

　　The operating system of Iphone, which is very popular in recent years, was developed by Apple based on its experience in PC operating system MAC OS X. At present, it is the only one with no semicolon.

　　5. BlackBerry operating system

　　The operating system used by Blackberry seems to have only been imported from China Mobile in China, and the others are parallel imports, with high cost performance.

　　6. Palm operating system

　　Plam system, which was once very popular, is declining now. However, with the announcement of Plam Pre last year, it seems that it has become popular recently, but it uses another operating system, Plam Web OS.

　　7. Palm Web OS operating system

　　The system launched with Plam Pre has aroused people’s countless reverie before, but now it seems disappointing according to the preliminary evaluation.

　　8. Linux system

　　In fact, many operating systems use Linux, such as Motorola’s e6 and e680, and Nokia’s n770, n800 and n810. Coolpad also has a mobile phone with Linux system.

　　9. Android system

　　The mobile phone operating system led by google is actually based on Linux.

　　What are the types of operating systems and what are their characteristics? I will simply introduce them to you here. If you are particularly interested in operating systems, you may wish to find out more about relevant information through Baidu search.

Cassano： Football has developed, Mourinho is out of date, and Lu Kaku makes me feel sorry.

As an old general of Rome and Inter Milan, Cassano talked about the contest between the two former clubs in this round of Serie A, and finally the focus battle ended with the Nerazzurri winning 1-0 at home.

"Inter played a good game and they deserved to win the game. Thuram has scored nine goals and assists, and he started the season very strongly, which surprised me, of course in a positive way. Besides, I’m also happy for Aslani. He did well after coming off the bench. Varela also played a good game and he began to recover. Inter didn’t encounter any difficulties, only Sommer blocked Cristante’s great header once. Inter played well and they played in their comfort zone. This is Inter Milan, they have a strong team, have their own ideas and confidence, and they are the biggest favourites for the Serie A championship. Cassano said on Bobo TV, a live program in vieri.

"Mourinho Ideally, there is only one difference: if Eto ‘o, Milito and Sneijder are present, he will do more, but his first consideration is not to concede a goal, and then if you have strong players, you will score sooner or later. When I said he was not a good coach, I meant that Mourinho would not give you anything. When he has a champion player, he is excellent, and he will make you feel important. He is very strong in this respect, but today’s football is no longer like this. Football has developed, and strong teams no longer buy his tricks. Manchester United sent him away, Tottenham also sent him away, and Rome will send him away in the future. It is easy to coach a champion player. "

"Lu Kaku made me feel sorry for him: he was already in trouble, and everyone booed him in this game, but Inter fans didn’t need to boo him at all. Where did you expect Rome to play like that? Mourinho is very cunning, he changed the subject, and his communication style is suitable for those who follow him. None of the reporters asked him what he thought of the game and how he organized it. Why did you play so badly? Are you scared? People like Mourinho have a good life in Italy. Luck will end sooner or later, just like allegri. He won’t let the team pass the three-legged ball in a row. Only when the team he coached is strong can he win the championship. He has strong players in Porto and a super team in Inter Milan. He put two buses in front of the door when he played against Barcelona. Of course, that’s no problem. At home against Barcelona, he won the game by an offside goal and his opponent’s failure to blow a penalty, but his luck will end sooner or later. I don’t care that he took Rome to the finals twice. De Zerbi and Belsa may not have won the championship, but you will be excited when you see their teams. I’d rather not win, but play good football and make people happy. Mourinho is like this, I have said so for a long time. Inter gave him a dance music, but you didn’t even shoot straight through the goal. You just played for 0-0. What are you talking about? "

Gerrard plays football so well, can I have a pair of football shoes？ Get out! Get out! !

Original title: Gerrard is so good at football, can I have a pair of football shoes? Get out! Get out! !

England’s national team, Gerrard’s story revealed 17 years later.

Micah Richards, a former member of the English national team, gave up his brilliant career as a player and showed his talents through media comments, revealing an episode of national team members related to the legendary Steven Gerrard. On 14th, the Sports Bible exposed an episode in which Gerrard insulted Richards when he participated in the football podcast The Rest Is Football, which drew laughter. Richards recalled the time in 2006, which was an anecdote that happened during the training of the England national team. Richards was the first player to be called up to the national team at that time, and Gerrard was one of the players who established himself as a key member of the national team and has been participating in international competitions since 2000. Richards told Gerrard an anecdote. He said, "When I train, I always bring two pairs of football shoes, one is artificial lawn, and the other is natural lawn." However, when Richards checked whether he brought his football shoes to the national team training, he couldn’t wear them because all football shoes only fit his left foot. I borrowed Gerrard’s football shoes from the corridor I met in the team training center. Richards said, "At that time, I borrowed a pair of football shoes from Gerrard. I said,’ Stevie, can you lend me a pair of football shoes? Our feet are the same size.’ "Gerrard willingly gave up his football shoes. The problem is that Richards performed very well in training in Gerrard’s football shoes.After the training, I went to Steven Gerrard and asked if I could buy some football shoes. But Gerrard is so cold. "Gerald said without thinking,’ Fuck off,’" Richards said. Richards’ words made the talk show audience burst into laughter. Gary Lineker, The 1986 Mexico FIFA World Cup’s top scorer and a celebrity representing English football, sarcastically said: "This is why Richards has only been selected for the national team for 13 times." Richards also talked about his England teammate Jolyon Lescott, a defender who played for Everton and Manchester City. Richards said, "Lescott confessed to me during the national team training (playing for Everton at that time) that he wanted to come to Manchester City." Subsequently, Richards conveyed the matter to Mark Hughes, then Manchester City coach, and explained that Manchester City Club was also paying attention to Lescott. However, it turns out that coach Hughes is making a deal to send Richards to Everton after bringing Lescott from Everton. Richards said that after learning this fact, he was very angry and said, "I did all the work to recruit him." In the end, Lescott joined Manchester City in 2009, and Richards played in Manchester City until 2015. There was no transfer, so they could play together. Richards moved to Aston Villa in 2015 and retired in 2019. In addition, Lescott and Richards moved to Aston Villa together and will play until 2016.

The stars are dim! The American men’s basketball team lost to the sparring team in succession, but coach Cole said it was ＂tradition＂

The high-profile American men’s basketball team has concentrated in Las Vegas to prepare for the Men’s Basketball World Cup. These days, the American men’s basketball team is playing a warm-up match with the sparring team for 10 minutes in two consecutive games, but the American men’s basketball team has lost to the sparring team, which makes the outside world have more worries and even doubts about this team that lacks star flavor. However, coach Cole has different views on this. He thinks that the American men’s basketball team has always been like this before, and losing during the preparation period has become a "tradition".
In the face of this year’s World Cup, NBA bigwigs are still uninterested. At present, the established American men’s basketball team lacks absolute superstars and is even regarded as the worst team in history by the outside world. It is true from the talent of players. The core lineup of this American men’s basketball team includes Ingram, Halliburton, bridges and Jackson. Although they are all-star players, they are still far from superstars. Comparatively speaking, the coach lineup of the American men’s basketball team is luxurious, with Warriors coach Cole in command, Clippers owner Bruu and Heat coach Spostra, who are NBA champion coaches.
All the players of this mediocre talent American men’s basketball team are playing the World Cup for the first time. People are not optimistic about what they can do. The fact that this team lost to the sparring team in a row during the concentration period aggravated the worries of the outside world.
However, Cole did not agree. He said, "This is a tradition of the American men’s basketball team, and everyone knows about it. In 2019, that is, in the last World Cup, the sparring team kicked the ass of the team. This is the point. You want the best players to join the sparring team to challenge you. This is what the sparring team is doing now. "
The 2019 Men’s Basketball World Cup was a disgraceful record of the American men’s basketball team. At that time, there was also a lack of heavy players to help them, and they finally got the seventh bad result. However, when the American men’s basketball team went to the Tokyo Olympics and many superstars returned, they won the Olympic champion as they wished. At that time, Cole was an assistant to the American men’s basketball team, assisting the then coach Popovich. Now Cole, who is the coach, is likely to go back to the past.
