How does ESD occur?

Answer 4

When two objects that store different amounts of static electricity come in contact.

Question 5

How can you avoid ESD?

Answer 5

• By keeping yourself and the computer parts you are working with at the same electrical potential (grounding yourself to the computer device).
• You can keep yourself grounded by either using specialized equipment or by periodically touching the power supply (Equipment Grounding).

Question 6

Answer 6

The act of periodically touching the power supply of a device to keep the electrical potential between you and the device the same.

Question 7

What is Electromagnetic Interference (EMI)?

Answer 7

Occurs when electrical signals from one device disrupt the operation of another device nearby. It can cause malfunctions, noise, or even complete failure in electronic systems.
