  1. What does IIoT stand for in the context of Industry 4.0 manufacturing?

    Answer: Industrial Internet of Things

    IIoT stands for Industrial Internet of Things — the network of sensors, devices, and machines on the shop floor that collect and share real-time production data to improve efficiency and decision-making.

  2. Which Industry 4.0 technology overlays digital information onto a technician's view of real equipment to assist with maintenance or assembly?

    Answer: Augmented reality (AR)

    Augmented reality (AR) overlays computer-generated information — such as assembly instructions, part labels, or fault indicators — onto the real-world view of machinery, helping technicians work faster and with fewer errors.

  3. Additive manufacturing (3D printing) builds parts by:

    Answer: Depositing material layer by layer from a digital model

    Additive manufacturing builds objects by adding material layer by layer based on a digital CAD model, allowing complex geometries that traditional subtractive machining cannot easily produce and reducing material waste.

  4. On a smart factory floor, IIoT sensors on machines primarily help production teams by:

    Answer: Collecting real-time operational data to monitor performance and predict failures

    IIoT sensors capture real-time data on temperature, vibration, cycle times, and other parameters, enabling predictive maintenance, faster troubleshooting, and continuous process improvement without requiring manual data collection.

  5. In an Industry 4.0 environment, autonomous robots are most commonly deployed to:

    Answer: Perform repetitive, precise, or hazardous tasks that benefit from consistent automation

    Autonomous robots excel at repetitive, high-precision, or hazardous tasks — such as welding, painting, or heavy material handling — improving safety and consistency while freeing human workers for tasks requiring judgment and problem-solving.

  6. Big data analytics in a manufacturing context is primarily used to:

    Answer: Identify patterns in production data to optimize processes and reduce defects

    Big data analytics processes large volumes of machine and process data to surface patterns — such as which conditions predict defects or downtime — enabling data-driven decisions that improve quality, efficiency, and equipment reliability.
