What is the meaning of hacking?

Hacking refers to the act of gaining unauthorized access to computer systems, networks, or devices, often with the intention of manipulating, stealing, or destroying data, or disrupting the normal functioning of the targeted system. Hacking can be performed by individuals or groups known as hackers, who possess advanced technical skills and knowledge of computer systems and networks. While hacking is often associated with illegal activities, there are also ethical hackers, known as "white hat" hackers, who use their skills to identify vulnerabilities in systems and help improve their security.
