itTechnologyThe development is changing with each passing day, and people's pursuit of technology has never stopped. However, there are still some surprises behind this fast-paced digital age, and their concept of hardware and software configuration that keeps up with the times seems to be incompatible. Take the German Bahn system, for example, it actually requires candidates to be familiar with Windows 3 in the recruitment announcement11 systems, even want to have a proficient experience in the use of MS-DOS.
The hardware configuration of the German railway system is even more impressive. The computer processor they used was only 166MHz and the RAM was only 8MB. Such a backward configuration is quite outdated in today's high-performance era. This is especially true when compared to today's high-speed trains, such as ICE1 (401) and ICE2 (402), which are the most advanced EMU trains in Germany. However, even such top-of-the-line trains still use old hardware systems.
windowsforworkgroups3.The 11 system was released in the 1993 year, and it was considered a revolutionary update. This version of Windows introduces network and LAN functionality for the first time, as well as plug-and-play technology, making it easier for users to do soFile sharingand printing. However, with the continuous advancement of technology, Windows 311 announced its retirement in November 2008, and Microsoft no longer provided maintenance support.
Despite Windows 3The 11 system was considered a major breakthrough at the time, but today it seems that its functionality and performance are similar to those of modern timesOperating systemIt does seem very limited in comparison. However, for some critical systems, such as rail and air traffic systems, remain stable andReliabilityMore important. Therefore, for these systems, managers have always adhered to the principle of "don't use it if it doesn't break, use it when you can", and even use configurations that are decades old.
For some mission-critical systems, stability andReliabilityis the first consideration. In the railway system, the safety of passengers is the most important part. Therefore, in order to ensure the stability of the system, the railway management opted for an old configuration and system. Although these configurations are relatively outdated, they have been proven to be reliable after a long period of validation and testing. At the same time, replacing configurations and systems for these systems is not a simple task, and the costs and risks involved are very high. Therefore, as long as they can be operated stably, these systems will continue to be used.
The same is true in other critical systems, such as the United StatesNuclear**Manage. It wasn't until a few years ago that they began phasing out floppy disks and updating their hardware and systems. This once again confirms the principle of "don't move if it's not bad, and use it if you can".
Observe the phenomenon that the German railway system still uses old hardware and software configurations, as:TechnologyAs a bystander of development, we should think about the reasons and implications. While we pursue innovative and high-performance technologies, we also recognize that for some specific tasks and areas, stability and:ReliabilityProbably more important than the latest technology.
Of course, this does not mean that we should stop pursuing technological progress. On the contrary, we should strive to ensure stability andReliabilityOn the premise of continuous exploration and innovation. Technological development should be purposeful and rational, rather than blindly pursuing the latest and trendiest things. Only in this way can we truly contribute to the progress of humanity.
In general, the German railway system still uses DOS and Windows 3The fact of the 11 system may surprise some, but from the stability andReliabilityThis choice is not meaningless. Passenger safety is a top priority for critical systems, and older configurations and systems have proven to be reliable over time in terms of stability. However, this incident also reminds us that while pursuing technological progress, we should also think about the applicability of technology for specific fields and tasks, and how to promote it while ensuring stability and reliabilityTechnologydevelopment.
