 to machine code. An assembly language text file is fed into an assembler and a
 binary object file containing machine code is returned.
 
-## Relation to instruction set architectures
+A disassembler does the opposite: translate machine code into assembly.

+### Relation to instruction set architectures
+
+- the ISA defines the hardware capabilities and the instructions that can be run
+  on the hardware
+- machine code is a binary representation of these instructions and can be
+  directly executed by the CPU
+- humans use an assembly language version of the machine code which is then
+  translated back to machine code for the computer to execute.
