How many volts of electricity is sufficient to damage computer components?

30 Volts

What precautions should one take to prevent damage of computer components via ESD (electrostatic discharge)?

• Keep all components in antistatic bags until you are ready to use them.
• Use grounded mats on workbenches.
• Use grounded floor mats in work areas.
• Use antistatic wrist straps when working on computers.

Define EMI (electromagnetic interface)

The intrusion of outside electromagnetic signals in a transmission media.

EMI distorts signals so that receiving devices have difficulty interpreting them.

What are the sources of EMI?

• Any source designed to generate electromagnetic energy.
• Man-made sources like power lines or motors.
• Natrural events such as electrical storms, or solar and interstellar radiations.

In what ways does climate effect computer equipment?

• If the environment temperature is too high, equipment can overheat.
• If the humidity level is too low, the chances of ESD increases.
• If the humidity level is too high, equipment can suffer from moisture damage.
