What problem can occur if a printer cable is to close to a power cable? A. ESD Electrostatic Discharge B. EMI Electromagnetic Interference C. parity error D. no affect E. None of the above

The correct answer is: B. EMI Electromagnetic Interference

Electromagnetic interference (EMI) is a disturbance generated by an external source that affects an electrical circuit by electromagnetic induction, electrostatic coupling, or conduction. The disturbance may degrade the performance of the circuit or even stop it from functioning.

In the case of a printer cable being too close to a power cable, the EMI from the power cable can cause interference with the printer cable. This can result in data errors, print quality problems, or even damage to the printer.

The other options are incorrect because:

• ESD (Electrostatic Discharge) is a sudden discharge of electricity that can occur when two objects with different electrical charges come into contact. It can cause damage to electronic components, but it is not likely to occur in the case of a printer cable being too close to a power cable.
• Parity error is a type of error that can occur when data is being transmitted. It is caused by a mismatch between the parity bit of the data and the parity bit of the received data. Parity error is not likely to occur in the case of a printer cable being too close to a power cable.
• No affect is incorrect because EMI can cause problems with printer cables.
• None of the above is incorrect because EMI is the most likely problem to occur if a printer cable is too close to a power cable.
