Computer forensics is a branch of digital forensic science that is concerned with evidence found in computers and other digital storage media. This field is also referred to using the term computer forensic science. The goal of this field of study is examining digital media forensically with the intention to identify, preserve, recover, analyze, and present opinions and facts concerning digital information therein. The professional who does this job is called a computer forensic expert.
Digital forensic science is a new field with a relatively short history. Its creation and development was made necessary by the increase in the number of people who owned personal computers in the 1980s. People used personal computers as tools for committing computer-related crimes.
