A minor niggle there: machine code is the native language of the computer. Assembly language is a slightly higher-level and slightly less expressive language. Most of the time, they can be seen as equivalent, but as a trivial example, a generation of us had to DB Z80 opcodes when using an 8080 assembler. More practically, things like breakpoints have to be set by writing binary to memory - there is no assembly language involved. At a less practical level, you can have things like self-modifying code, or code where the meaning changes depending on what byte offset you start.
