what is a hacker?

First, what is a hacker?
The term "hacker" can mean two different things:
- Someone who is very good at computer programming, networking, or other related computer functions and loves to share their knowledge with other people
- Someone who uses their expert computer skills and knowledge to gain unauthorized access to systems, corporations, governments, or networks.
- What most people think of when they hear the term "hacker"
- The word "hacker" does not bring the best of thoughts to most people’s minds. The popular definition of a hacker is someone who intentionally breaks into systems or networks to illegally procure information or infuse chaos into a network for the express purpose of control. Hackers are not usually associated with doing good deeds; in fact, the term "hacker" is often synonymous with "criminal" to the public. These are black-hat hackers or crackers, the folks we hear about on the news creating chaos and pulling down systems. They maliciously enter secure networks and exploit flaws for their own personal (and usually malicious) gratification
