Chapter 1-3 Quiz: Safety Issues, Measures, and Procedures

What is the primary risk of static electricity (ESD) to computer components?

• It can cause components to overheat.

• It can cause components to become physically larger.

• It can zap and damage components, even with less than 30 volts.

• It can slow down the processing speed of the CPU.

Which of the following is NOT an ESD protection measure mentioned?

• Using antistatic bags to store components.

• Using grounded mats on workbenches.

• Using regular wool sweaters while working on computers.

• Using antistatic wrist straps when working on computers.

What is the purpose of connecting an antistatic wrist strap to the metal chassis of a computer?

• To increase the computer's processing power.

• To keep your body at the same voltage (potential) as the computer, preventing ESD.

• To provide additional power to the computer.

• To allow for faster data transfer.

To ensure you and the computer are at ground potential when using an antistatic mat, you should:

• Lay the computer on the mat and connect the mat to a reliable electrical ground.

• Only place the computer on the mat.

• Connect the computer to the mat but not to an electrical ground.

• Wear rubber-soled shoes.

What is a potential consequence of exchanging AC adapters between different types of laptops or devices?

• It may improve performance for both devices.

• It may cause damage to both the AC adapter and the laptop.

• It will not affect either device.

• It will only damage the AC adapter.

When installing or removing computer hardware, which type of apparel should be avoided?

• Cotton shirts

• Acrylic or wool sweaters

• Polyester pants

• Leather shoes

Before opening any covering cases of computer equipment, what is the first safety step?

• Put on an antistatic wrist strap.

• Unplug all computer equipment and peripherals.

• Ensure the work area is well-lit.

• Check for damaged parts.

If excessive force is needed to remove or add a computer component, it likely indicates that:

• You are using the wrong size screwdriver.

• Something may be wrong with the component or installation.

• The component is designed to be difficult to install.

• The computer needs more power.

Why should magnetized tools NOT be used around electronic devices?

• They can cause electrical shorts.

• They can damage the surface finish of components.

• They can interfere with or damage magnetic storage media and potentially other electronic components.

• They are too difficult to handle.

What is a potential risk of using a pencil inside a computer?

• The pencil lead can act as a conductor and damage components.

• The pencil can scratch internal components.

• The pencil can absorb moisture.

• The pencil can cause static buildup.
