Assemblers
Assemblers translate assembly code into executable binary.
Assemblers
- Assembly is a very low-level programming language.
- Each instruction directly corresponds to a binary sequence, and the assembler replaces the commands with the relevant binary.
Pros of assemblers
- Assembly provides exact control over the hardware:
- This can lead to very efficient code that takes up little space in memory and is quick to execute.
- Assembly can be used on low specification machines.
Cons of assemblers
- Assembly is very difficult to use, and needs deep technical knowledge of the central processing unit and the memory.
