You are in a carpeted office lighted by fluorescent bulbs. You are preparing to add memory modules to a user's computer. The user has already unpacked the memory modules and stacked them on top of an old, unused CRT monitor. What is the greatest threat to these memory modules in this environment? answer Electromagnetic interference (EMI) from the fluorescent lights. Electrostatic discharge (ESD). The magnetic field around the CRT monitor. High-voltage discharge from the CRT monitor.
Question
You are in a carpeted office lighted by fluorescent bulbs. You are preparing to add memory modules to a user's computer. The user has already unpacked the memory modules and stacked them on top of an old, unused CRT monitor.
What is the greatest threat to these memory modules in this environment?
answer
Electromagnetic interference (EMI) from the fluorescent lights.
Electrostatic discharge (ESD).
The magnetic field around the CRT monitor.
High-voltage discharge from the CRT monitor.
Solution
The greatest threat to these memory modules in this environment is Electrostatic discharge (ESD). This is because memory modules are sensitive to static electricity. If someone touches the memory modules without first grounding themselves to discharge any static electricity built up on their body, they could inadvertently send a surge of electricity through the module, damaging it.
The other options, such as Electromagnetic interference (EMI) from the fluorescent lights, the magnetic field around the CRT monitor, and high-voltage discharge from the CRT monitor, while potentially harmful, are not as immediate or likely a threat as ESD in this scenario.
