The restriction of communication to only machines of the same brand. The ability of workers to perform multiple different jobs. The ability of machines to operate without electricity. The ability of different cyber-physical systems, humans, and Smart Factories to connect and communicate. Q2. How does maintenance typically differ between conventional automation and Industry 4.0? Industry 4.0 requires no maintenance. Conventional uses predictive maintenance; Industry 4.0 uses reactive maintenance. Both rely entirely on breaking down before repairs are made. Conventional uses preventive/reactive maintenance; Industry 4.0 utilizes predictive maintenance. Q3. Which statement is true regarding flexibility in production? Conventional automation is highly flexible for custom orders. Industry 4.0 enables mass customization and agile manufacturing. Industry 4.0 requires changing physical layouts for every new product. Both systems are completely inflexible once set up. Q4. What are "Cobots" in the manufacturing sector? Robots used exclusively for mining raw materials. Collaborative robots designed to work safely alongside humans. Computer bots that write software for factory machines. Robots that strictly replace human workers. Q5. What is meant by "decentralized decisions" in a Smart Factory? The CEO makes all decisions from a remote office. Decisions are made by a vote among factory floor workers. Machines and cyber-physical systems make autonomous decisions based on real-time data. No decisions are made; the factory runs randomly. Q6. What role does Big Data play in Industry 4.0 manufacturing? It is used to fill up hard drives to justify IT budgets. It is analyzed to optimize processes, improve quality, and predict trends. It is primarily used to track employee break times. Big Data is obsolete in Industry 4.0. Q7. What is a "Digital Twin" in the context of modern manufacturing? An exact virtual replica of a physical product, process, or system. A highly advanced 3D printer. A human worker who operates two machines simultaneously. A backup generator for the factory. Q8. What technology helps workers in Industry 4.0 by overlaying digital information onto the physical world? Artificial Intelligence (AI) Augmented Reality (AR) Virtual Reality (VR) Blockchain Q9. Which of the following is a significant cybersecurity risk associated with Industry 4.0? The depletion of local power grids. Machinery rusting due to less human supervision. The hacking of interconnected production networks and data breaches. Increased risk of physical theft of machinery. Q10. What primarily characterizes the Fourth Industrial Revolution (Industry 4.0)? The introduction of the assembly line and mass production. The widespread adoption of early computers and basic PLCs. The transition from manual labor to steam-powered machinery. The integration of cyber-physical systems, IoT, and network connectivity. đ¯ Complete My Submission
