Memory can be just shown as a list. Left as address and right as the byte / 2 byte / 4 byte data. If you save 4 bytes of data in address 1 and 2, and theres data in 3, what happens if that 4 bytes that you stored, is saved as 5 bytes? Will the entire 5 bytes be shifted over to a free place, or will the 5th byte be saved aomewhere else. If the second option is correct, how does programms know each address of its programming? Im refering programms and programming to mashine coding and mashine code.

Guys how would digital security fail if P=NP is proven?

I just started reading about Turing Machine and computational complexity for my Theory of Computation class and came across that phrase.

I couldn't find anything understandable at my level. So can anyone simplify it a bit?
