Definitively, knowledge is the understanding of facts and information by education. It was said by Plato that knowledge is the "justified true belief". In other words, it's the information which accepts both conditions of truth and belief; hence, resulting with a true belief. But of course, this justification requires proof and evidence.

Justified True Belie

Some factors that affect knowledge are its accuracy, consistency, and desirability. The more accurate an information is, the more accepted it is as a knowledge, and so does for consistency and desirability. Let's show a simple example, 2+2=4. Not only knowing that 2+2=4, you've probably know how to add two numbers, person, place, or any object. That's the main thing about knowledge. Based on philosophical point of view, is that it's divided generally into "knowledge that" and "knowledge how". Knowledge that or know-that is most probably a belief instead of truth, but might also be truth. While know-how, mostly tacit knowledge, refers to facts and information a person knows how to get, but hard to explain by written words. So back to the equation, simply by learning 2+2=4, a person might actually be able to learn hoe to add 2 different numbers and apply it in daily life. However, if this equation or theory of addition never came into his life, that means that this person will never gain knowledge of addition. Which questions the existence of knowledge. Where do they really come from? Is it as simple as studying from school or Internet? Another example is, 'a person builds a bridge and said it's safe to cross it' but when he crosses, it collapsed. This means he didn't knew but instead believed, which means his belief that the bridge could support him, which was not, was false, and considered as, not a knowledge, but belief instead.
Now, wisdom on the other hand, is the ability to use experience and knowledge for common sense and intuition, usually obtained by constant observing day-to-day activities. What makes wisdom differ from knowledge is that it remains constant with time, while knowledge changes over time. Wisdom is usually symbolized with an owl, since owls can see through 'darkness', and by darkness, it means the unknown.
Another thing is, wisdom is universal, while knowledge is still undergoing further researches. An example to explain their difference is, "A person died from an unknown disease". Now let's analyze the sentence again. Knowledge-based, we don't know what caused the death, which means they have to undergo researches to know the cause. Wisdom-based, on the other hand, all we know is that the person has died, and there comes a time when a person must die, and this is universal no matter how much you deny it, everyone will have that time where they 'sleep'. While knowledge on the other hand still needs proofs, and even if they did find the disease causing the death. Is the 'disease' the only factor that played in this death scene? No! There might be age-related factor or genetic factor. There is no simple conclusion to the death, and even if there were, some people might not accept it.
Back to the main thing, a knowledge-less person doesn't refer to wisdom-less, and vise versa. This can be seen in a lot of religious histories. 'Stupid' people often gain enlightenment when they encounter the religious image (Jesus, Buddha, Allah, etc.), and this doesn't say that he gained knowledge, instead, wisdom. An intelligent person might not be wise yet, and vise versa. So as far as we can see, wisdom doesn't have to refer to an intelligent person. And as Albert Einstein said:

"Wisdom is not a product of schooling but a lifelong attempt to acquire it."

Proving that wisdom is harder to obtain, and this is probably the reason why religious icons are honoured. And to end this post, I'll add a quote to hope you understand the difference between wisdom and knowledge.

"To attain knowledge, add things everyday. To attain wisdom, remove things every day" - Lao Tzu
