Low-Level Languages
Low-level programming languages are languages which are much closer to computer-understandable binary.
Low-Level Languages
- Low-level languages (LLLs) are much closer to executable machine code than high-level languages.
- LLLs are harder to read by humans, but are easier to read for the computer.
What does an LLL look like?
- LLL commands are not easy to read, and might include commands such as:
- MOV ax, bx
- CMP ch, dh
- CLI
Why do we use LLLs?
- LLLs provide exact control over the central processing unit.
- LLLs need less translation, and often lead to faster code which is useful for computers with low specifications such as embedded systems.
