A(n) ________ machine is a computer running software that allows for an instance of an operating system, or multiple operating systems, without making any changes to the user's computer

Fill in the blank(s) with the appropriate word(s).

Answer: Virtual. In other words, after the user terminates a virtual machine session, the computer's configuration remains unchanged. If a criminal uses virtual machine software to perpetrate criminal activities, this makes the work of the computer forensics examiner difficult because little or no evidence relating to the suspect's activities can be found on the computer.
