- Assembly Language is used to control directly computer hardware via communicating with the OS.
- Assembly Langauge could be used to design programs on embedded systems.
- Just by studying Assembly Language, we could have a better understanding about the computer architecture and operating system.
- Benefits of programming in Assembly Language are speed, versatility, flexibility, and compact.
- 'Versatility' means that anything that can be done with a computer can be done with Assembly Language.
- 'Flexibility' means that there exists multiple ways to accomplish one task than High Level Languages.
- After compiling, the assembler and linker, loader changes into a binary code that the computer can read.
- 'Assembler' converts assembly code into machine code.
- 'Linker' combines individual files into a single executable program.
- In programming language analogy, 'Langauge L0' is a native machine language read by the computer, while 'Language L1' is a more human-friendly language usually constructed above machine langauge.
- 'Interpretation' is the L0 program interpreting and executing L1 instructions one by one.
- 'Translation' is L1 program being completely translated into L0 program, and then running on the computer hardware.
- Assembly Language has a one-to-one relationship with machine language.
