A computer is used in many purposes. However, at first, a computer that was very colossal, was introduced to largely numerical calculate. Thus, there were computers in only huge organizations such as banks, university or important ministries. The time was passed and the computer was developed; its size is smaller, its price is cheaper, its ability is more. Nowadays, there are computers in almost every household, office and organization. A computer is used as a television, a home theater, a calculator, a radio, a text book or a window that can sees the global, etc.
Conversely, a computer can be used to be a criminal’s equipment. Namely, criminal uses computer to crack network that is not allowed by administrator, uses computer network to piracy, uses computer on risqué way.
