## Definition

a person or a computer program that translates very simple code into a language the computer can run directly. It is often used for very fast or low-level programming.

For teachers: a person or a program that converts assembly language into machine code. Often used in the context of low-level programming or hardware development.

## Examples

- The assembler translates the code into machine language.
- Writing the kernel required using an assembler to ensure the code ran as efficiently as possible on the hardware.
- While high-level languages abstract away the hardware, an assembler provides direct control over the processor's registers and memory addresses, making it essential for specific performance-critical tasks.
