There is a longstanding controversy about the term’s true meaning. In this controversy, the term hacker is reclaimed by computer programmers who argue that it refers simply to someone with an advanced understanding of computers and computer networks. A developer or somebody who hacked out computer codes. A hacker can “hack” his or her way through the security levels of a computer system or network.

Hackers are the reason software manufacturers liberate sporadic “security updates” to their programs. To avoid hacking strong the security of your networking computer otherwise all the data can be stolen by the hacker with unauthorized access to your computer system. 

This can be as simple as finding out somebody else’s password or as complex as writing a institution program to break another computer’s security software.
