"Never plug an ATX power supply into AC power unless it is connected either to a computer's motherboard or to a dummy test load." Inference: Why is this rule in place for an ATX power supply?
To prevent the power supply from overheating due to lack of airflow.
To ensure the user follows the proper sequence of assembly.
ATX power supplies require a minimal load (like the motherboard or test load) to regulate output voltages correctly and safely.
Connecting it directly will immediately cause a short circuit.
Why is it explicitly forbidden to eat, drink, or smoke while working on a computer?
It takes too much time away from the task.
It prevents the technician from concentrating.
To prevent spills, ashes, or crumbs from contaminating and damaging sensitive internal components.
It can lead to static electricity buildup.
The module states that PPE can be used to protect the working environment from infection from the worker, "for example in a microchip factory." What does this imply about the dual purpose of PPE?
It only protects the worker from hazards.
It only protects the environment from the worker.
It can protect the worker from hazards AND the work environment (and components) from the worker.
It must always be disposed of after use.
Why must a computer be disconnected from both the AC power and any powered peripherals (like a USB printer with its own power source) before working on it?
Disconnecting peripherals is only a courtesy.
Powered peripherals do not pose any electrical hazard.
Any connected powered device can still create a potential path for stray voltage or current into the system's components.
It makes the computer lighter and easier to move.
A technician is about to install a stick of RAM and is only wearing an anti-static wrist strap. They decide not to first grasp a metal part of the chassis with their bare hand. How would this choice be rated according to the module's safety rules?
Excellent, because the wrist strap is sufficient on its own.
Acceptable, as long as they are also wearing gloves.
Poor, because the module requires grasping the metal chassis even when wearing the wrist strap for added discharge protection.
Neutral, it has no effect on safety.
What is the potential consequence of touching the pins or other connectors of an electronic component instead of its non-metallic edge?
The component will scratch easily.
The component will fail to fit into its slot.
Body oils, dirt, or a static charge from the hand could damage the sensitive electrical contacts or circuits.
It will void the component's warranty.
What is the most significant difference between the static shock a human feels (several thousand volts) and the voltage needed to damage a computer component (less than 30 volts)?
Static electricity from a person is always stronger.
The computer component is made of different materials.
Computer components are vastly more sensitive to lower voltage electrostatic discharge (ESD) than humans are to feeling a shock.
The air is more conductive around the computer.
