all items; all parts; all points
Used when referring to every member of a set counted or treated as individual points/items, such as products, works, parts, questions, or listed points. Often appears in written, business, retail, exhibition, or explanatory contexts rather than as a general everyday word for everything.

全数 emphasizes the total count or quantity of items (as in 全数調査), while 全点 emphasizes each individual item or point within the whole set.
一部 means 'a part/some' of a set, directly contrasting with 全点's meaning of 'every single item/point' in that set.
A transparent kanji compound: 全 means 'all' or 'entire,' and 点 here means an individual item, part, or point. This is a component explanation of the spelling, not a claim about historical origin.
