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...

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

FALSE
One of them did
I think it was Waters
He asked him what does he think of the album and he replied...well i dont exactly remember but it was something negative !

Sorry to correct you - albeit slightly - but I was referring to the initial entry of Barrett. In a later interview, Richard Wright said:
"One thing that really stands out in my mind, that I’ll never forget; I was going in to the the Shine On sessions. I went in the studio and I saw this guy sitting at the back of the studio, he was only as far away as you are from me. And I didn’t recognise him. I said, ‘Who’s that guy behind you?’ ‘That’s Syd.’ And I just cracked up, I couldn’t believe it… he had shaven all his hair off… I mean, his eyebrows, everything… he was jumping up and down brushing his teeth, it was awful. And, uh, I was in, I mean Roger was in tears, I think I was; we were both in tears. It was very shocking… seven years of no contact and then to walk in while we’re actually doing that particular track. I don’t know – coincidence, karma, fate, who knows? But it was very, very, very powerful.”
Waters described the meeting as:
“I had no idea who he was for a very long time.”

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.

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.

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!

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.

Erm...not quite. Each core is an "independent" processor which is part of the CPU - and two or more cores can be doing different things at the same time.

OP asked in the context of a machine with one [single core?] CPU.
