Answer 1

The programmer wrote a a programmer, the compiler/assembler took the stuff he wrote and re-wrote it so a machine could understand it.
So for example it might write.
JMP 0x2131 meaning go to the part of the code marked 0x2131.
All of this would be written in binary so it would be:
111010010010000100110001

You then opened it with notepad.
Basically, you told notepad, here’s a bunch of text, read it like a text file.
So it looks up, what “11101001” is, then what “00100001”, then what”00110001″ is.
Which is “�!1”

Because you told it this was a text file, when it’s an instruction set.
