What is hacker And its type ?

In the computer security context, a hacker is someone who seeks and exploits weaknesses in a computer system or computer network. Hackers may be motivated by a multitude of reasons, such as profit, protest, challenge or enjoyment

Hackers are three types:-

1.    White hat hacker
2.    Gray hat hacker
3.    Black hat hacker


What Is A White Hat Hacker?
 
Today, anyone can become a hacker. Within that denomination, there are three types of hackers. The first one is the black hacker, also known as a cracker, someone who uses his computer knowledge in criminal activities in order to obtain personal benefits. 

On the other side is the white hat hacker. Although white hat hacking can be considered similar to a black hacker, there is an important difference. A white hacker does it with no criminal intention in mind. Companies around the world, who want to test their systems, contract white hackers. They will test how secure are their systems, and point any faults that they may found. If you want to become a hacker with a white hat, Linux, a PC and an internet connection is all you need.



Grey Hat Hackers

A grey hat hacker is someone who is in between these two concepts. He may use his skills for legal or illegal acts, but not for personal gains. Grey hackers use their skills in
order to prove themselves that they can accomplish a determined feat, but never do it in order to make money out of it. The moment they cross that boundary, they become black hackers.




Black Hat Hackers

Black hat is used to describe a hacker (or, if you prefer, cracker) who breaks into a computer system or network with malicious intent. Unlike a white hat hacker, the black hat hacker takes advantage of the break-in, perhaps destroying files or stealing data for profit. The black hat hacker may also make the exploit known to other hackers and/or the public without notifying the victim. This gives others the opportunity to exploit the vulnerability before the organization is able to secure it.

Note :
There is another type of hacker know as Ethical Hacker.Who work or do hacking for the organization or individual by following ethics.They didn't mean to do for any profit.This concept was first used by US army.They use this to find out any loop hole present in their army.
