Forensic science is the application of scientific knowledge to legal matters. This means that crime investigations are assisted by processing evidence using scientific methods. Cyber forensics is a subset of forensic science for processing digital evidence. Cyber forensics does not necessarily apply to legal matters. It encompasses a large number of activities, from computer crime investigations to locating specific data on digital devices. Cyber forensics is not limited to crimes or incidents committed with computers. It also includes the processing of electronic data from mobile devices such as cellular telephones, personal digital assistants (PDAs), music players, or microchips with storage capability.
