If you hear of computer forensics, the first thing in the sense a Crime Scene Investigator may appear to pull the plastic sheet by a computer and check for signs of a struggle. Nobody has ever really talked about science in everyday life, until he started on prime time cop shows scientifically accurate, so natural, simple word association usually results in us that forensic science to do "something of policemen, is not it ?
Among other things, the science behind Computer forensics is not really much different from that of forensic science including crime scene.

The same applies to the computer. You can not do everything on a computer without> Computer experts are able to understand exactly what you did to.
