Education/knowledge

What is knowledge?
Knowledge means to understand an idea or concept. When a person has the capacity and ability to use and act on an idea or concept understanding is achieved and knowledge is acquired. Knowledge may also be narrowly defined as an idea or concept that is understood and believed to be true. How knowledge is acquired is the subject of many theories and research efforts in the field of Epistemology.

Types/kinds of knowledge
One way of generating knowledge is by experience. This knowledge is of two kinds:
 * 1) Priori knowledge: It is acquired independently of experience. For example, telling a child that the certain object is a pen.
 * 2) Posteriori/Empirical knowledge: Posteriori literally means afterward. So, this knowledge is acquired through experience.
