It appears that some are upset about the reputation people earn. I have received several downvotes without any feedback, so I don't think there is a problem with my answer. This answer has received 2 downvotes. Is it possible for a meta user to suspend an account for someone that has posted many downvotes?
Your answer does not explain anything; it's just two sentences. There's more valuable information in the comments to your answer than in the post itself.
By all means, I see no reason it should not be downvoted – if only to encourage you to improve it. Just because you didn't receive any feedback doesn't mean your answer is without problems.
Note: The question is too broad anyway, since it would require a much too long answer, covering what embedded systems are, and how they run for every imaginable device. Perhaps it can be more focused.
Your answer is woefully short considering the scope of the question asked and is borderline wrong.
I did not down vote it, but I was very close as it only barely answered the question.
All computers can and do run some amount of precompiled code, not just embedded systems. The difference is that higher powered processors with more memory available can support and run larger programs. Embedded systems can still run multitasking systems such as FreeRTOS and the only real difference these days is the size and scope of the programs that run on each system.
You could have said so much more in your answer and in my opinion there are some borderline off topic questions such as this one that can be saved from closure by great answers, yours was not that answer.
