What is a Computer Hacker ?

A Hacker is a programmer who breaks into computer systems in order to steal or change information as a form of cyber-terrorism.

Case: In 1999 a 19 year old Russian hacker named Maxim broke into an e-commerce (Amazon.com) web site and stole 300,000 credit card numbers, demanding $100,000 from the site owners, and threatened to post all the credit card numbers on the Internet if he did not get the money.

What is a Computer Virus?

A computer virus is a computer program that can copy itself and infect a computer without the permission or knowledge of the user.

Case: In 1974, the Rabbit virus infected computers, as a result, it reduced the system’s performance just before the computers crashed.

As of today there has been over 51 world known computer viruses that has affected millions of computers.

Viruses can be avoided, and reinstalling a computer’s operating system is a known approach of removing viruses.
