Final answer:
Hacking refers to the unauthorized access of a computer system to view or change data. Hackers use various techniques to compromise information, sometimes leading to identity theft, which involves using a person's personal information illegally.
Step-by-step explanation:
The unauthorized use of a computer system with the intent to view or modify data without permission is often referred to as hacking. Hackers employ various methods to break into websites, entice users into clicking malicious links, and manipulate individuals into divulging sensitive personal information. In extreme cases, this might lead to identity theft, also known as 'True-name Fraud', where a person's personal identification, credit, or account information is wrongfully acquired and used without their permission. Identity theft can result in severe financial damages, such as emptied savings accounts or fraudulent large purchases.
