FASM

FASM (Flat Assembler) is a software tool used to translate human-readable assembly language code into machine code that a computer's processor can execute directly. Assembly language provides a way for programmers to write instructions close to how the hardware operates, allowing for highly efficient and precise control. FASM simplifies this process by offering a fast, flexible, and easy-to-use assembler specifically designed for x86 architecture. It is popular among developers who need to create low-level programs, optimize performance, or develop system components, providing a clear pathway from writing code to running it on hardware.
