Hi ! I've some doubt regarding multiprocessing and mutlithreading
D
Ты не в курсе, что есть ещё генту?
Не скажу что с генту гемора больше чем с другими. Поставил и забыл. Зато есть свои плюсы.
A
does multiprocessing always mean that the different processes run on different cores of the CPU?
A
If they run on a single core, then does it mean that the system is muli-tasking?

Not really. There is a thing called system interruptions that enables your computer to execute multiple tasks at the same time. In fact it does not mean that microcommands getting executed at the same time - CPU is just switching between execution of microcommands for different processes.
This "switching" also wastes a lot of resources, so that is why, for example, node.js is multiple times faster than php in most cases

are you talking about context-switching between different processes?

Yep

And I think operating systems are smart enough today to utilize maximum out of cpu resources
A
so isn't context-switching across multiple processes called multi-tasking?
A
I'm confused b/w mulit-tasking and multi-processing
AD
So yeah, if there are multiple processes and multiple cores, than OS should automatically try to utilize all cores
AD
Ajay

I'm not sure if multitasking is applicable word in context of operating systems
A
Also, in when multiple threads of a given process are run then they run parallelly instead of context-switching, right?
