Operating system for DOS
Operating system for DOS
... it's not used. Or at least it shouldn't be used (assuming you're referring to the almost-40-year-old system). I doubt it's even used for legacy systems (or at least I hope it isn't), similar to how many US nuclear silos are still using 40 year old systems There is literally no use or reason to use DOS in a company. https://en.wikipedia.org/wiki/DOS
It was suggested by someone familiar with its typical use. In today’s call centre environment, it would actually reduce efficiency to the point where operations couldn’t function properly. The system only has very limited RAM—around 640KB—and requires separate memory pools that are isolated from one another, preventing apps in higher memory areas from accessing each other. It lacks native networking support, and any external framework would consume all available RAM. The only reason it might still exist is for basic telephony functions, but there’s no compelling need to maintain it now.
I tried to be passive-aggressive, but you're right—I was incorrect. Both of your points are valid.
You’ll discover that many older programs aren’t running on DOS itself but instead use AS400 or comparable server systems such as Lightspeed, which offer a terminal-like interface reminiscent of DOS. Most of this legacy code is built on outdated Unix kernels.
There are still some DOS-based programs running in industry today, as I mentioned. It's fortunate I can work with a few at my current job. This highlights how much legacy remains. Most of these tools aren't used by clients because they focus on internal data handling.
The focus isn't on DOS applications disappearing entirely, but they remain relevant in niche scenarios such as data handling. What I was saying was that the majority of what appears to resemble DOS from a user's viewpoint is likely not DOS itself—more likely a Unix or AS400 style terminal.
