Final answer:
Option 1 is the correct definition of cybercrime, which is any illegal act that involves a computer or the systems and applications associated with it. Cybercrime not only includes identity theft but also a wider spectrum of criminal activities such as hacking, cyberbullying, and unauthorized access.
Step-by-step explanation:
What is Cybercrime?
Cybercrime is broadly defined as any illegal act involving a computer, or the systems and applications associated with computers. This definition is most accurately aligned with Option 1: Cybercrime means any illegal act that involves a computer or the systems and applications associated with it. Cybercrime encompasses a wide range of criminal activities which can include identity theft, hacking, cyberbullying, and other forms of unauthorized access or cyberattacks. Option 2 (Cybercrime is the same as identity theft) is incorrect because identity theft is actually just a subset of cybercrime, not its entirety. Option 3 (Cybercrime is any illegal act that involves a criminal using a computer) is also incorrect as it does not necessarily represent the full scope of activities, systems, and applications that can be involved in criminal activities.
It's important to note that cybercrimes can range from minor offenses to serious transnational issues that affect global security. Cybercriminals may use computers to commit crimes against individuals, such as harassment or identity theft, crimes against property, such as intellectual property theft or ransomware attacks, and they can even participate in crimes against governments by hacking into systems to access sensitive information or disrupt services.
