Knowledge is defined as the remembering of previously learned material by recall or recognition. This may involve the recall of a wide range of material from specific facts to complete theories, but all that is required is the bringing to mind the appropriate information. It answers the question
what is known?

The previous learning is relatively unaltered in the process.

Knowledge includes:

1. Memory of specifics: It is the ability to recognize or recall definitions, symbols, terminology, specific facts (dates, names, places, events, sources of information, define terms and vocabulary words).

2. Memory of ways and means of dealing with specifics: It includes knowing (in a passive way) the ways and means of dealing with specific (organizing, studying, judging and criticizing) information. It includes:

Memory of trends and sequences	Memory about classifications and categories
Memory of criteria	Memory of methodology

3. Memory of universals and abstractions in a field: It is the memory of the principles, generalizations, theories, concepts, and patterns. It is having the ability to recall or recognize statements of relationship between two or more concepts. This includes:
