Computer forensics is a sub-set of digital forensics. At one time the terms were synonymous, but with the growth of all types of digital storage devices, there was a need to distinguish between the two terms.
The goal of computer forensics is to examine computer storage systems and extract useful information from them in a forensically sound manner. That information can be used in a number of ways, including criminal cases, but also in personal investigations and the possible investigation of a cheating spouse.
Personal computers became available and accessible to individuals beginning in the early 1980s, and, of course, that led to their being used in crimes, such as fraud. It was then that the discipline of computer forensics emerged. There was a need to recover and investigate digital evidence for use in court, both in criminal trials and civil litigation.
All of the rules of evidence apply to computer forensic evidence no matter if it is a criminal or civil case, although those rules change between those two different types of investigations. Computer forensics is now widely accepted as valid both in the United States and in Europe.
The scope of forensic analysis can vary. It can be as simple as information retrieval or as complex as the reconstruction of a series of events. Even at this point some still believe that computer forensics is more art than science.
