Tell us, what is a hacker?

A hacker is a person who likes to use his intelligence and creativity to challenge the limits of his brain, especially in the fields they are interested in, such as computer programming or electrical engineering.

Hackers originated from English hacker, and were highly respected in American computer field in the early days. But in media reports, the word hacker often refers to those "software crackers".

The word hacker originally refers to computer experts, especially programmers, who are enthusiastic about computer technology and have a high level.

But today, the word "hacker" has been used to refer to those who use computers to sabotage or play pranks. The correct English name of these people is Cracker, which translates as "hacker"

The fundamental difference between hackers and hackers is that hackers build and hackers destroy.

Others call hackers hackers hackers.

The word hacker generally has the following four meanings:

A person who knows enough programming languages can create useful software without long thinking.

Malicious (usually illegal) attempts to crack or destroy programs, systems and network security. This meaning will often bring serious trouble to those qualified hackers (1). They suggested that the media call this group "hackers". Sometimes these people are also called "black hat hackers".

For example, the famous hacker "master" in China is a professional black hat hacker who uses the loopholes in the system to achieve the purpose of invasion and infiltration.

An attempt to crack a system or network to warn the system owner of a system security vulnerability. This group of people is usually called "white hat hackers" or "anonymous" or honker. Many of these people are employees of computer security companies, attacking a system under completely legal circumstances.

A person who modifies a program (usually good) through knowledge or speculation and changes (or enhances) the purpose of the program.

"script kiddies" refers to those who have no or only a little hacking skills, but can achieve the purpose of cracking as long as they follow the instructions or run some hacking programs.
