There are three general types of evidence:
--> Best evidence: can be presented in court in the original form (for example, an exact copy of a hard disk drive).
--> Corroborating evidence: tends to support a theory or an assumption deduced by some initial evidence. This corroborating evidence confirms the proposition.
--> Indirect or circumstantial evidence: extrapolation to a conclusion of fact (such as fingerprints, DNA evidence, and so on).
