China DOS Union

The poster has a very strong personal emotional color, but it can be seen that you don't know much about Windows programming, or that you have the ability to understand DOS but not the ability to understand WINDOWS (this statement sounds unfriendly, but there's no other meaning, don't misunderstand), although Windows is not open, no one should doubt its logic, rigor, and completeness (can anyone say that Windows is not well done), if the function of the application program is not perfect, you can only find the problem from yourself.

Admired! Study hard and make progress every day!~~

Hehe, please give me more advice~! Great person!!!!!

No, now the price of memory is too low. How much is a 2G memory? How much is a 1G memory card?
As long as electromagnetic compatibility is well done, Windows can work normally and stably in harsh environments.
Windows is much more stable than DOS! This...

Is the satellite in the sky, do you install a CPU with a power consumption of 80 watts? And huge hard drives and memory, then do you still need a radiator? Solar panels are also very expensive... The CPU in the building only has a power consumption of 0.9 watts, which can be reduced... The most advanced torpedo in my country still uses a 486 control... If real-time control is required, Windows is even more unacceptable... For industrial and military control, the CPU of the building can work in the range of -50~+150 degrees Celsius. CPUs that can work in that environment generally have a low frequency, and it is difficult to run Windows. In addition, embedded control generally does not use a hard drive. Where can I find such a large memory?

Do you think that WINDOWS can only run on P3, P4 CPUs????
You are too ignorant, besides, WINDOWS also includes Wince, haven't you heard of it?
There are too many ultra-low power consumption CPUs, you figure it out first before coming!

What I said about windows generally includes a batch of advanced and complex operating systems such as linux, not just the MS one!

Quote: China's most advanced torpedoes still use 486 control..
Have you seen it?? Are you sure, controlling a torpedo doesn't need an operating system at all! Not all industrial controls need an operating system!

Quote: Embedded control generally doesn't use a hard disk
Of course, hard disks are unstable, but you can use memory cards and the like, and now electronic hard disks have come out, and the price will drop soon

Quote: CPUs that can work in that environment generally have a low frequency, and it's difficult to run Windows
You can run Windows with 100M. The high CPU requirement of Windows is only because of multimedia drawing! If you don't need multimedia, no matter how bad the CPU is, it's okay!



What is the purpose of us using an operating system?? Have you figured it out?
1. General stable platform
2. Convenient for us to write programs!

Whoever says that writing programs under DOS is more convenient than under Windows must have never written programs under Windows! Just simple multi-threading, DOS is very difficult to do! (Of course it can be done, but debugging is complicated, and writing is also complicated)

The only advantage of DOS is that this hardware system and software system are cheap! And indeed, a lot of things can be done, and very complex controls can also be done!
This is in line with China's national conditions!

But if it goes on like this, it will only make our technology lag far behind foreign countries!
Wake up!

Bump up, the moderators haven't shown up for years

Envious... Every time I come back, I will see some posts that make my heart surge

Choosing what operating system mainly depends on what you use it for. Specific issues are analyzed specifically
I believe that many programmers are currently writing under Windows. But you need to know that directly operating hardware under DOS is much more efficient. For some places that require fast speed, Windows is very helpless. You say 100M is very fast? Unless only the system is running... I admit, I'm just an amateur
In my opinion, DOS is a simple and efficient system, Windows is an easy-to-use and rich system. DOS is suitable for occasions that do not require a graphical interface and have high requirements for speed, efficiency, and volume, and are suitable for professional and bottom-layer familiar programmers;
Windows is suitable for office, entertainment and other graphical interface and multimedia applications, and is suitable for mass programmers.

Microsoft encapsulates everything for you. Programming under Windows is like building blocks. The underlying operations are all encapsulated by Microsoft. This is different from under DOS. It's like you ask me which is better between 51 single-chip microcomputer and P4. Is there a comparison?

Really envy your abilities. We are just moving around on Windows now

For embedded applications, the main operating systems used are "DOS", "Linux", "Win CE", etc. The choice of which operating system to use generally considers:
(1) System volume and power consumption
(2) System complexity
(3) The proficiency of enterprise programmers in programming under this system
(4) Maintenance cost of system code
(5) Copyright fees

Generally speaking, the "DOS" system is better for single-threaded scenarios, and "Linux/WinCE" is better for "multitasking" scenarios.

Many people have a wrong view: "Any embedded application written under DOS is low-end and backward, and any embedded application written under Windows or Unix is high-end". This view is very wrong. We must break the "two凡是" ideology and not be superstitious. After all, we are engaged in scientific research!

At least under DOS, controlling hardware is much more convenient than under WINDOWS. Also, for real-time performance in embedded systems, it is better than WINDOWS control. The system resource consumption is much smaller than that of WINDOWS. I am in the textile machinery field and find that the use of WINDOWS operating systems for this area is very rare. The DOS system can be combined with UC/OS for multi-tasking. Even in the current era of popular USB ports, there are drivers and ICs that can be added under DOS to easily read and write USB drives, etc. The DOS system is indeed very stable for control.

It's getting more and more confusing.

Top, I've been developing under DOS all the time, using allegro + djgpp, looking forward to communication. QQ: 729504816
