Introduction to Computer Engineering MCQs (Part-13)
What is the primary purpose of ethical hacking?
A Develop malware
B Hack into systems
C Protect systems from attacks
D Install software
Ethical hacking involves legally testing and identifying vulnerabilities in computer systems to improve security. Ethical hackers help organizations safeguard their data by simulating potential attacks and finding weaknesses before malicious hackers can exploit them.
Which of the following is NOT a tool used by ethical hackers?
A Windows Defender
B Nmap
C Wireshark
D Metasploit
Windows Defender is a security tool that protects against malware and viruses, but it is not specifically designed for ethical hacking. Metasploit, Nmap, and Wireshark are common tools used by ethical hackers to test vulnerabilities and monitor network traffic.
What is a primary responsibility of a robotics engineer?
A Develop software applications
B Write operating systems
C Manage computer networks
D Build and program robots
A robotics engineer is responsible for designing, building, and programming robots. They apply principles of mechanical, electrical, and computer engineering to create autonomous or semi autonomous machines used in various industries, from manufacturing to healthcare.
What type of security threat does ethical hacking aim to address?
A Software bugs
B Data breaches
C Network congestion
D Hardware failures
Ethical hacking focuses on identifying and addressing vulnerabilities that could lead to data breaches. By identifying weaknesses, ethical hackers help organizations prevent unauthorized access to sensitive data and protect their digital infrastructure from cyberattacks.
In robotics, what does the term “actuator” refer to?
A Movement mechanism
B Power source
C Sensory device
D Control system
An actuator in robotics is a component responsible for creating movement. It converts energy (such as electrical or hydraulic) into mechanical motion, enabling robots to perform tasks such as gripping objects or walking.
What is the primary concern of cybersecurity in ethical hacking?
A System performance
B Protecting data integrity
C Hardware repair
D Speed optimization
The primary concern of cybersecurity in ethical hacking is protecting data integrity. Ethical hackers test and secure systems to ensure that data is not altered, deleted, or stolen by malicious actors, maintaining the trust and security of systems.
Which programming language is commonly used for robotics programming?
A C++
B Ruby
C Python
D JavaScript
C++ is commonly used in robotics because of its efficiency and ability to handle complex operations. It allows robotics engineers to write programs that control robot behavior, process sensor data, and interact with hardware in real time.
What is the role of ethical hackers in preventing cyberattacks?
A Create malware
B Test vulnerabilities
C Monitor traffic
D Analyze threats
Ethical hackers play a critical role in preventing cyberattacks by testing vulnerabilities within an organization’s systems. They simulate cyberattacks to find weaknesses, which helps the organization address those weaknesses before they can be exploited by malicious hackers.
What is a common feature of most modern robots?
A Artificial intelligence
B Large physical size
C Limited sensors
D Single function
Many modern robots integrate artificial intelligence (AI) to improve their functionality. AI allows robots to learn from their environment, make decisions, and adapt to different tasks, making them more versatile and autonomous.
In ethical hacking, what is a “penetration test”?
A A code compilation
B A system reboot
C A software installation
D An attack simulation
A penetration test is a controlled attack simulation performed by ethical hackers to identify vulnerabilities in a system. By mimicking the actions of malicious hackers, ethical hackers assess the system’s security and help strengthen it.
What is the importance of a robot’s “sensor” in its operation?
A Detect environmental changes
B Provide movement
C Control power
D Interpret data
Sensors in robots detect environmental changes, such as temperature, proximity, or light. This information allows robots to respond intelligently to their surroundings, navigate obstacles, and perform tasks autonomously or semi autonomously.
What is one of the primary benefits of ethical hacking?
A Writing new software
B Reducing system cost
C Identifying and fixing vulnerabilities
D Making systems faster
Ethical hacking helps organizations by identifying and fixing vulnerabilities in their systems. By discovering weaknesses before malicious hackers can exploit them, ethical hackers improve the overall security and resilience of the system.
What is the role of an “end effector” in robotics?
A Hardware assembly
B Gripping mechanism
C Building robots
D Control system
The end effector is the part of a robot that interacts with the environment to perform tasks, such as gripping, picking, or welding. It is typically the robotic “hand” or tool that allows robots to manipulate objects or tools.
How does AI contribute to the development of robots?
A Enabling decision making and learning
B Storing data
C Programming control systems
D Creating physical components
AI contributes to robotics by enabling robots to make decisions based on data and learn from experiences. AI allows robots to adapt to new environments and tasks, increasing their autonomy and efficiency in various applications.
Why is ethical hacking important for organizations?
A To find and fix security flaws
B To test employees
C To increase network speed
D To create software
Ethical hacking is important because it helps organizations find and fix security flaws before malicious hackers can exploit them. Ethical hackers simulate attacks to identify vulnerabilities and strengthen systems against future threats.
