Yesterday I discovered that a hardware store in French is a quincaillerie [kɛ̃.kaj.ʁi]. This word can also refer to hardware, ironmongery or junk, or in French, une ensemble hétéroclite de choses inutiles (a motley collection of useless things) [source]

Quincaillerie comes from quincaille (hardware, utensils) a variant of clincaille [klɛ̃.kaj], which is related to clinquant [klɛ̃.kɑ̃] (flashy, kitsch, pretentious), from clinquer [klɛ̃.ke] (to rattle, make a metalic noise), which comes from the onomatopeic word clic (click).

Similar words exist in Spanish: quincallería (hardware store) and quincalla (low-value hardware, junk). They were borrowed from French [more details].

Incidentally, the word clinquant [ˈklɪŋkənt] also exists in English, and was borrowed from French, which was possibly borrowed from Dutch klinken (to sound, ring, clink), As an adjective it means glittery, gleaming, sparkling, dressed in, or overlaid with, tinsel finery, and as a noun it means Dutch metal, tinsel or glitter [source].

Computer / IT hardware is matérial (informatique) or hardware in French [source] and computer software is logiciel [source].
