Computer hacking is when someone modifies computer hardware or software in a way that alters the creator’s original intent. People who hack computers are known as hackers. Hackers are usually real technology buffs who enjoy learning all they can about computers and how they work. Hackers think that what they do is like an art form. They usually have expert-level skills in one specific program. For most hackers, hacking gives them the opportunity to use their problem-solving skills and a chance to show off their abilities. Most of them do not wish to harm others.
