What of the following best describes the relationship between machine code and assembly language?

Assembly code is a symbolic representation of machine code. Machine code is made up 1's and 0's.

In assembly, you move around data into registers. There are many different types of registers, some more special than others. But we will focus on the four general purpose registers:

EAX
EBX
ECX
EDX

And those registers are broken down into even more smaller registers.
I'll put an image at the bottom.

Also, because assembly is basically functions that are in the processor, and that every processor is different, you're gonna find out that programming assembly for one machine might be different from another one...

Ibelieve its true but not sure hope this .
