What does hacking do?

Answer 1

Hacking is the act of finding and exploiting weaknesses in computers, networks, software, or devices to gain access, control, or information. It can be used for legitimate purposes, such as security testing, vulnerability research, and improving defenses, when performed with authorization, or for malicious ends like data theft, financial fraud, service disruption (DDoS), spying, or installing malware.

Techniques range from social engineering and phishing to exploiting software bugs, misconfigured systems, or weak credentials. The effects of hacking vary from minor privacy breaches to large-scale financial loss, reputational damage, and threats to public safety, depending on the attacker’s intent and the target. Defensive measures—patching, strong authentication, network segmentation, monitoring, and security training—help reduce the risk and impact of hacking.

Answer 2

Hacking is basically the vast knowledge of computers or any particular thing. For a computer hacker you should have vast knowledge of computer or in other words you must know everything about everything.

There are different types of hackers and the work they do depends on their category.

Ethical Hacker or White Hat Hackers do only ethical hacking like securing computers from malicious viruses and activity. They trace the path of the virus and other things.

Black Hat Hackers do only non ethical things or malicious things for harming the computer like hacking email accounts, sending Trojans, stealing, and lots of illegal things related to computers.
