assembly language

Assembly language is a low-level programming language that uses human-readable mnemonics to represent machine code instructions—the binary operations a computer's processor actually executes.

Each assembly instruction typically corresponds to one machine instruction: MOV AX, 5 might move a value into a register.

Assembly gives programmers direct control over hardware, making it useful for operating systems, device drivers, and performance-critical code, but it's tied to specific processor architectures and far more tedious than higher-level languages.
