## Summary
|
||||
|
||||
- Machine code is hard for humans to parse, even in
|
||||
[[Hexadecimal_number_system|hexadecimal]]
|
||||
|
||||
- Assembly is one level up from machine code and provides a more human-friendly
|
||||
abstraction layer
|
||||
|
||||
- An assembly instruction is a _mneumonic_ that comprises an "op code" plus
|
||||
operands
|
||||
|
||||
## Detail
|
||||
|
||||
### Example instruction
|
||||
|
||||
We can translate the machine instruction `e3a07004` into the assembly
|
||||
instruction `mov r7, #4`. This translates to: _move the value number 4 to the
|
||||
register r7_.
|
||||
|
||||
### Assemblers
|
||||
|
||||
Although assembly is useful for humans, computers still work at the level of
|
||||
machine code. Therefore you need an **assembler** to translate the assembly code
|
||||
to machine code. An assembly language text file is fed into an assembler and a
|
||||
binary object file containing machine code is returned.
