registers question

You are in the wrong place! We sold all our EIP's for food...
I'm not questioning your powers of observation; I'm merely remarking upon the paradox of asking a masked man who he is. (V)

So after the sale did the EIP's point to the first thing that you, or the byuer will do next?
Me of course! Buyer do not know about computers - he thinks EIP is some innovation think...

Suppose we run two programs on a single-core processor First sets the EIP pointer to 2 (example)and the second one sets it to 1 How does the first program know it will continue from adress 2 and not 1 ? Thank you very much (random fact: Pink Floyd's wish you were here was written not for someone who died ,but for an ex member who went insane)

Random random fact: While recording Wish You Were Here, the same former member wandered into the recording and none of the band recognised him.

Syd Barrett[^] was the driving force and one of the original members of Pink Floyd. He released 2 solo albums; The Mapcap Laughs and Barrett but they didn't go very well. I have The Mapcap Laughs and it is a very strange album.
Along with Antimatter and Dark Matter they've discovered the existence of Doesn't Matter which appears to have no effect on the universe whatsoever! Rich Tennant 5th Wave

Each program runs in its own address and activity space, totally isolated from the other. As one is pre-empted, its environment, including registers, is saved and then restored when it gets its next timeslice.

So far 45 minutes have elapsed and nobody has suggested your answer is incomplete or theirs is better. I vote we move Q&A to the Lounge and post drivel in Q&A. All in favor raise your hands...

Where's the change in that? :confused:

both of his solo records are great. and they've influenced a ton of artists over the years.

Obviously it can't work that way, precisely because of the reason you give. So why is this even a question?

Not everyone understands how a multi-tasking operating system works. Certainly plenty of "developers" in Q&A would seem not to.
Even though they may not know how it works, it should be immediately obvious that the way OP implied it might work is definitely impossible, especially since OP gave an argument for why that is so. If you prove something can't work, then obviously it doesn't work that way.

Yes, but only if you have an undestanding of how an OS works, which is not always obvious to students, and others who are learning.

Just to add to the context switching answer... The thing to remember is the CPU can only do one thing at once... just really really fast. Running two apps at once or two threads in an app at once is simply a software construct in things like the Windows subsystem. Hardware doesn't care.

No. I'm not saying it should be obvious how a multi tasking OS works. I'm saying that it should be obvious that if you disprove a theory, that means it's wrong.
Only if you think scientifically. "Intelligent Design" has it's adherents, despite being a load of old cobblers...
