ARM assembly language is a low-level, RISC-based programming language used to communicate directly with ARM processors. It is widely used for embedded systems, mobile devices (iOS/Android), and IoT hardware. Because it interacts closely with hardware, it enables highly optimized, fast, and memory-efficient software.

The fundamental difference between ARM assembly and MASM assembly is that ARM is a hardware architecture specification (RISC) while MASM is a software tool (an assembler) designed specifically to compile assembly code for Intel/AMD x86 and x64 hardware architectures (CISC). They feature completely different instruction sets, design philosophies, and target ecosystems.
