Digital forensics is a branch of forensics science that involves the recovery and investigation of data stored in digital devices, such as computers, smartphones, and other electronic devices. The purpose of digital forensics is to identify, preserve, analyze, and present electronic data in a manner that is admissible in a court of law.

Digital forensics is used in criminal investigations to gather evidence for use in legal proceedings, such as prosecuting cybercrime, intellectual property theft, and other offenses. It is also used in civil litigation to provide electronic evidence in support of claims and defenses. Additionally, digital forensics is used in internal investigations to determine whether employees have violated company policies, engaged in misconduct, or have compromised sensitive information.

In short, the purpose of digital forensics is to provide impartial and scientifically-based evidence for use in legal proceedings and other investigations, thereby contributing to the administration of justice and the protection of individuals and organizations.
