To talk about knowledge, it is necessary to talk about data, it is a mixture of codes and information is the result of the process of manipulating that data, so knowledge can be considered information with a utility.
Knowledge is divided into a series of categories: sensory knowledge, which is common knowledge between humans and animals; intellectual knowledge that is the reasoning, the thought of the human being; popular knowledge which is the form of knowledge of a particular culture; scientific knowledge which is evidence-based analysis; philosophical knowledge that is linked to the construction of ideas and concepts and theological knowledge that is knowledge gained from faith.
Scientific knowledge is real knowledge because it deals with occurrences or facts, it constitutes contingent knowledge, because its prepositions or hypotheses have their veracity or falsity proven through experimentation and not just by reason, as it occurs in philosophical knowledge.
But the empirical knowledge , is that we have acquired in the course of the day, is done through trial and error in a grouping of ideas; Empirical knowledge is knowledge that does not need scientific proof.
