I heard it through the grapevine. This is an idiom that means ” I learned the information because I was gossiping.”

Coat and Quote are similar, but not the same. “Quote” starts with a /kw/ sound, but “coat” starts with only /k/.

“Software” and “hardware” are noncount. If you want to use count expressions, say “pieces of software,” “apps,” or “programs.” For “hardware,” say “computers,” “devices,” or “tablets/phones/laptops.”
