GNU Assembler

The GNU Assembler (GAS) is a software tool used by programmers to convert human-readable assembly language into machine code that a computer's processor can execute directly. Assembly language provides a low-level way to control hardware, making programs faster and more efficient. GAS translates these instructions into binary, enabling the computer to perform specific tasks. It's part of the GNU toolset and supports various computer architectures, helping developers build and optimize software at a very detailed hardware level. Essentially, GAS acts as a bridge between written assembly instructions and the computer's understanding of those commands.
