Answer:
Cyber crime is an illegal act conducted online.
Explanation:
There are 3 main types of cyber crime; crimes in which the electronic device is the target, crimes in which the electronic device is used as a weapon against other electronic devices, and crimes in which the electronic is used to engage in illegal and malicious activities.
In crimes where the electronic device is the target, the criminal will often use an electronic to gain access to a network and then often changes things in that network.
With crimes in which an electronic device is used as a weapon, the criminal will create certain "attacks" (eg. Dos attacks) to gain information.
Lastly, when an electronic device is used to engage in illegal activities, this means they are conducting a crime that is not limited to cyberspace, but they choose to do it online (eg. buying drugs off of the 'net).
