* Quiet refers to a lack of noise or activity.
* Quite means "to a considerable degree" or "very".
Here are some examples:
* Quiet: "The library was very quiet."
* Quite: "The movie was quite good."
It's important to note that "quite" can be a quantifier as well, in which case it functions as an adverb. For example, "I have quite a lot of work to do today."
