Sixth class Linux and other operating systems the difference

Currently running on the PC’s operating system are Microsoft’s MS-DOS, Windows, Windows NT, IBM’s OS / 2 and so on. Early PC users generally use MS-DOS, the operating system because the hardware configuration of the machine ask for much, and with the rapid development of computer hardware technology, hardware prices getting lower and lower, it can be relatively easy to improve computer hardware configuration, so start using Windows, Windows NT and other operating systems with graphical interfaces. Linux is a concern recently been the operating system, it is gradually accepted by the PC user. So, Linux and other operating systems the main difference is it? The following two aspects to be addressed.

First look at Linux and MS – DOS the difference between.


On the same system running Linux and MS-DOS has become quite common, it is to play a processor function, MS-DOS does not fully realize the function x86 processors and Linux completely in the processor to protect mode, and the development of the processor all the features. Linux can directly access all available memory within the computer, provide a complete Unix interface. The MS-DOS supports only part of the Unix interface.


Terms of use of cost, Linux and MS-DOS are two completely different entities. Compared with other commercial operating systems, MS-DOS relatively cheap, and the PC user has a very large share of any other PC operating systems are difficult to achieve the popularity of MS-DOS, because other operating systems costs for most PC users who are not a small burden. Linux is free, users can access the internet or other means its version, and can be free to use, cost concerns.


Function of the operating system is on, MS-DOS is a single task operating system, once user to run an MS-DOS applications, it dominated the system resources, users can no longer run other applications. Linux is a multitasking operating system, users can run multiple applications simultaneously.


Look at the Linux and OS / 2, Windows, Windows NT difference between.


From a development background to see, Linux and other operating systems the difference is, Linux is a more mature operating system evolved, and other operating systems such as Windows NT, are self-contained, without relying on the corresponding phase operating system. This distinction makes Linux users can greatly benefit from the contribution of Unix groups. Because Unix is ​​the world’s most widely used to develop the most sophisticated operating systems, it is the mid-seventies developed multi-tasking computer systems and supercomputers, although sometimes confusing interface, and the lack of relative concentration of the standard, but or grow to become the most widely used operating systems. Whether it is the author of Unix or Unix users, are that only a true Unix operating system, many computer systems (from PCs to supercomputers), there are versions of Unix, Unix users can get support in many ways and help. Thus, Linux as a Unix clone, will be equally appropriate support and assistance, direct ownership of Unix users in the strong position established.


From the cost point of view to use, Linux and other operating systems, the difference is that Linux is an open, free operating system, and other operating systems are closed systems, require compensation for the use. This distinction allows us to do a lot of money can get the Linux version and its development of application software. When we access the Internet, you will find almost all the available free software to run on Linux systems. There are many software vendors from a variety of Unix implementations, Unix developer, the developer of an open system approach to promote its standardization, but not a company to control the design. Thus, any software vendor (or Portland) can be achieved in a Unix implementation of these standards. OS / 2 and Windows NT operating system is a copyrighted product, its interface and design by a company controlled, and only those companies have the right to achieve their design, they are in a closed environment development.
