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.
