The physical hardware components of a computer system	The legal rights to creative works, such as software, music, and writings, produced by individuals or companies	The process of protecting computer systems from unauthorized access	The ethical guidelines for computer programmers and developers
2	How do computer viruses typically spread from one computer to another?	Through physical contact with infected hardware	Through infected email attachments, malicious websites, or USB drives	Through overheating of computer components	Through electromagnetic interference
3	What is the primary goal of computer security?	To prevent any unauthorized access to computer systems	To make computer systems faster	To maximize network bandwidth	To eliminate the need for passwords
4	What does privacy in computer ethics refer to?	The protection of personal information from unauthorized access or disclosure	The ability to access computer resources without restriction	The speed at which data can be transmitted over a network	The process of securing computer systems from malware attacks
5	Which of the following is an example of multimodal authentication?	Using a fingerprint and a password to unlock a device	Using the same password for different accounts	Using multiple devices to generate a one-time password	Using a single authentication server for all users
6	Unauthorized access refers to:	Access granted to users with proper credentials	Access denied to users without proper credentials	Access granted to users without proper credentials	Access denied to users with proper credentials
7	Which type of malware is designed to spread from one computer to another by attaching itself to executable files?	Virus	Worm	Trojan horse	Spyware
8	What is a common method used by worms to spread across networks?	Attaching themselves to executable files	Exploiting vulnerabilities in software to self-replicate and spread automatically	Hiding within legitimate programs and waiting for specific conditions to execute	Monitoring and collecting user information without their knowledge
9	What is the primary characteristic of a worm?	It replicates itself and spreads across networks without human intervention.	It attaches itself to executable files and spreads when the files are executed.	It hides within other programs and waits for specific conditions to execute.	It monitors and collects user information without their knowledge.
10	Which of the following is an example of unethical behavior in computer use?	Keeping software licenses up-to-date	Sharing confidential information without permission	Sharing confidential information without permission	Following company policies regarding internet usage
11	What does computer crime involve?	Ethical use of computer resources in business environments	Unauthorized access to computer systems for beneficial purposes	Illegal activities conducted using computer technology, such as hacking, fraud, and identity theft	The ethical guidelines for computer scientists and engineers
12	Which precaution helps prevent malware infections when browsing the internet?	Disable firewall protection	Click on pop-up ads and suspicious links	Download files from unknown sources	Avoid visiting suspicious websites and clicking on suspicious links
13	Why is computer security important?	To increase the speed of data transmission	To ensure the confidentiality, integrity, and availability of data	To maximize the number of users accessing the network	To reduce the cost of maintaining computer systems
14	What is the best practice to protect a computer from malware?	Disable antivirus software	Download software from untrusted sources	Keep operating system and software up-to-date, use antivirus software, and exercise caution when browsing the internet or opening email attachments	Share passwords with friends and family
15	What is the purpose of antivirus software?	To spread malware	To detect and remove malware from computer systems	To increase computer performance	To encrypt data for secure transmission
16	What is the main difference between a hacker and a cracker?	Hackers have malicious intent, while crackers seek to improve security.	Hackers are skilled computer experts, while crackers are inexperienced.	Hackers exploit vulnerabilities for personal gain, while crackers do so for altruistic reasons.	Hackers are illegal, while crackers are legal.
17	Which term refers to an individual who gains unauthorized access to computer systems for malicious purposes?	Hacker	Cracker	Cybercriminal	Script kiddie
18	What is the advantage of biometric authentication over traditional password-based authentication?	Biometric authentication is less secure.	Biometric authentication requires less processing power.	Biometric authentication eliminates the need to remember passwords.	Biometric authentication is easier to implement.
19	What is the difference between authentication and authorization?	Authentication verifies the identity of a user, while authorization determines what actions the user is allowed to perform.	Authentication determines what actions the user is allowed to perform, while authorization verifies the identity of a user.	Authentication and authorization are synonymous and refer to the same process.	Authentication and authorization are unrelated to user access control.
20	Which of the following is a common symptom of a malware infection?	Improved computer performance	Increased storage space availability	Unexplained changes to system settings or files	Reduced internet speed
21	What does cyberbullying entail?	Ethical use of computer resources in educational settings	Unauthorized access to computer systems for malicious purposes	Harassment or intimidation of individuals using electronic communication, often through social media or online platforms	The ethical guidelines for conducting research using computer technology
22	What is a potential consequence of ransomware infection?	Increased computer performance	Loss of important data or files	Enhanced system security	Improved network speed
23	Which type of malware disguises itself as legitimate software?	Virus	Worm	Trojan horse	Spyware
24	What is multimodal authentication?	Authentication using multiple devices simultaneously	Authentication using multiple biometric factors	Authentication using multiple passwords	Authentication using multiple authentication servers
25	Which authentication method requires users to provide something they know, such as a password?	Biometric authentication	Two-factor authentication	Knowledge-based authentication	Token-based authentication
26	What does computer ethics primarily concern?	Ensuring computers operate efficiently	Preventing unauthorized access to computer systems	Guiding the moral conduct of individuals and organizations in computing-related activities	Maximizing profits from computer technology
27	What is malware?	Software that enhances computer security	Software that helps improve computer performance	Software designed to disrupt, damage, or gain unauthorized access to computer systems	Software that provides entertainment on computers
