exec : execute a binary file and push arguments in. The stack

Fork : used to eat food

EXCELLENT EXPLANATION ( hello from national technical university of Athens - Greece)

[narasimhann]

The Best Explanation for fork() and exec() I ever saw. Hats off Sir !!

[lakshminarayanans]

Because of your c programming video today I have clear the 1st round of ZOHO... Really thank you sir

[shaiksoofi]

Sir it's🔥🔥🔥🔥..U are simply awesome..Why can't we find a professor like u in colleges???🙍🙍

[quratraja]

Thank You!
So, fork() function creates a duplicate copy of the same program with different process id. The process who calls fork() is called parent process while the newly created process with exactly same contents and different process is called child process.
Whereas exec() function is called with some argument by an already existing process. It replaces the existing process with the one referenced in argument. So the whole process is replaced by another with same process id of the older process. In fork (), process id changes while in exec(), process id remains the same. Fork produces duplicate while exec replaces the program.

[ismail]

Thanks sir
with respect from NIT Calicut

[bluechacha]

Very straight and clear explanation with simple example.

[saraswati]

I can't believe I finally got this <3

[nicolagigante]

If my college professors explained programming concepts like you do, many students would finish their degrees instead of dropping out!

[followying]

I got this, lessons on my class created the fear on me !
Thank you !

[manshushivam]
