MACHINE CODE
Machine code, also called machine language, is a computer language that is directly understandable by a computer's CPU (central processing unit), and it is the language into which all programs must be converted before they can be run.
Machine codes are binary numbers
-in MicroAsm every instruction set in the program source will be converted into a set of bytes, this set of bytes is called a machine code.
VARIABLES
Variable is a memory location. For a programmer it is much easier to have some value be kept in a variable named "var1".
