Assembly language is a low-level programming language that offers a direct interface to a system’s hardware. Unlike high-level languages like Python or Java, assembly is closely tied to the machine architecture, providing instructions that correspond one-to-one with machine code executed by the CPU. Assembly acts as a symbolic representation of machine instructions. It uses mnemonic codes (such as MOV , ADD , JMP ) to represent fundamental CPU operations. Each instruction typically translates directly into a binary operation that the processor executes. Because it gives precise control over memory access, processor registers, and instruction timing, assembly is used in performance-critical applications, embedded systems, device drivers, operating system kernels, and reverse engineering. Writing in assembly requires an understanding of the system architecture, especially the layout and function of registers, the stack, memory, and the instruction set specific to the target CPU.
