Definition of assembler

The word "assembler" is derived from its primary function: assembling. It originates from the process of taking low-level instructions written in assembly language and converting them into machine code that a computer can directly execute. The term "assemble" itself comes from the concept of putting together smaller parts into a larger whole, similar to how an assembler combines individual instructions into a complete program. This process of "assembly" was crucial in the early days of computing, before high-level programming languages were widespread.
