Comparison of Linux and Win2000 Operating System Reliability

Article Title: Comparison of Linux and Win2000 Operating System Reliability. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

Reliability is one of the most talked about topics today. It refers to the consistency of applications and services running on a computer. Reducing the potential factors that may cause system failures means improving the system reliability. Improving Reliability also means increasing the interval between two failures. Reliability works together with the system to defend against possible faults. When the system crashes, good reliability can ensure rapid system restart.

Comparison of Windows2000 and Linux Reliability

The comparison of systems must be based on the same standards and carry out the same functions, because no matter what system, as long as you add the application in it, it will increase its complexity, that is to say, it will increase the probability of system problems. Generally, we install the Linux system to act as a firewall, Web server, or email server. In contrast, windows is not that simple, and there are a lot of applications that come with the default installation. So, is it because the two cannot be compared? In fact, we can compare the reliability of the two from the following perspectives.

　　1. fault recovery

First, file protection in Windows 2000 accelerates recovery after a fault. When a Linux system encounters a very major fault, for example, the system cannot be guided, it is very difficult to recover. Windows 2000 is different, it has a file protection function, when the system encounters a fault, it can automatically put the server and its application in the shortest time, it is restored to the status before the fault and requires no user intervention.

In addition, DFS in Windows 2000 provides additional fault tolerance features. DFS allows you to create a large Virtual File System on multiple different servers. In a DFS share, if a server fails, the client automatically connects to other servers in the DFS share, and the services that the client can obtain will not change at all. Linux also has distributed systems such as CODA and AFS, but they have not yet obtained commercial support and are not ready for managing major tasks.

　　2. driver source

The driver signature ensures that all installed drivers are tested. Linux has fewer available software, and most of these software have not been officially tested. What will happen? When you install a new product, you always have to worry about whether it will conflict with existing applications in your system, resulting in system faults or even crashes. The driver signature feature of Windows 2000 is designed to address this issue. Drivers with this signature all come from trusted channels and have passed various tests, ensure that there is no conflict with your existing applications. Of course, those applications you have now must be reliable.

3,Authoritative evaluation report

Before the release of Windows 2000, Windows NT 4.0 was well received in the Reliability Evaluation Test of ZD Labs. Windows 2000, as an upgraded version of Windows NT4.0, has been released for a short period of time and has no formal authoritative evaluation report. However, we can see from the case analysis of media reports that, it is more reliable than Windows NT 4.0. For example, Windows NT has an obvious drawback, that is, whenever the system configuration changes, the system is often required to be restarted. After Microsoft noticed this, it made great improvements in Windows 2000. Most configuration modifications, such as IP address modification, do not need to restart the system, reducing the operation steps means reducing the possibility of failure and thus improving the system reliability. Relatively speaking, it is not long enough for Linux to enter the practical field. At present, there are no rich cases or first-hand testing materials to prove its reliability, linux is better than Microsoft's platforms. After the above discussion, do you know more about the reliability of the system? It is undeniable that the open source code and free use of Linux bring a huge potential market for it, but now it seems more like a stage for programmers to show their capabilities, for Linux, which has not yet stood the test of a large network environment, it is now asserted that its reliability is less scientific than that of Windows. For most common users, convenient and reliable products are their direct needs. Windows 2000 is a good choice.
