Plural of assembler; people or machines that put parts together to create finished products, or in computing, programs that convert code into machine language.
From assemble + -er suffix (one who does the action) + -s (plural). The computing meaning emerged in the 1950s as the technology developed.
Factory 'assemblers' and computer 'assemblers' show how the same word adapted to new technologies—both are translators, whether assembling car parts or converting human-readable code into what computers understand.
