Criminalist Tom Parauda is investigating the scene of a
crime involving a computer. After he arrives, he photographs the overall scene and takes close-up shots of all
the connections to the single computer involved, as well
as photos of the serial numbers of the computer and all
peripheral devices. Tom then labels the cord to each
peripheral device, then disconnects them from the computer. After making sure that all data in RAM has been
saved to the hard disk drive, he unplugs the computer
from the wall. What mistakes, if any, did Tom make?
