Assembly code vs Machine code vs Object code?

Question

What is the difference between object code, machine code and assembly code?

Can you give a visual example of their difference?

Answer 1

Assembly is short descriptive terms humans can understand that can be directly translated into the machine code that a CPU actually uses.

While somewhat understandable by humans, Assembler is still low level. It takes a lot of code to do anything useful.

So instead we use higher level languages such as C, BASIC, FORTAN (OK I know I've dated myself). When compiled these produce object code. Early languages had machine language as their object code.

Many languages today such a JAVA and C# usually compile into a bytecode that is not machine code, but one that easily be interpreted at run time to produce machine code.
