This is a question that philosophers have been discussing and debating since at least the time of  Socrates. What do we really know? How do we know what we know? How do we know that we really know what we think we know? Much of what people used to think they knew in former times has turned out to be either completely or partially false. So how do we know that what we think we know today is really true knowledge or just opinion or hearsay or superstition or something else? If two people "know" two different "truths" about the same question, such as religion, how can they both be right? The study of the nature and origin of knowledge is called epistemology.

We can say that all knowledge is information but all information isnot knowledge. Knowledge is all that we know - the basic manners, facts, information etc...
