Computer Forensics is the scientific study of computers or computer related data in relation to an investigation by a law enforcement agency for use in a court of law. While this technology may be as old as computers themselves, the advances in technology are constantly revising this science.
In the technological old days, computer forensics was mostly related to data dumps, printing out every keystroke that had been logged on a computer in a series of eight digits, all of them zeroes and ones. Literally cases of paper would be used for the printing of the materials. Systems analysts would then have to convert all of the data into hex and then translate the value into whatever the actual keystroke was. In this way, it was possible to go over all of the data and figure out at what point the computer and the corresponding program crashed. Like computers and technology, Computer forensics has evolved by leaps and bounds since those days of old.
