It is the modern forensic technic came existence. • PERSISTANT DATA Meaning data that remains intact when the computer is turned off.

(deleted files, computer history, the computer's registry, temporary files and web browsing history).
- 10. Forensic tools • Typical forensic analysis includes a manual review of material on the media, reviewing the Windows registry for suspect information, discovering and cracking passwords, keyword searches for topics related to the crime, and extracting e-mail and pictures for review. • Disk Imaging Software. • Software Write Tools. • Hashing Tools. • File recovery programs. • Analysis Software. • Password cracking software.
