A user is experiencing intermittent power losses with their desktop computer. The IT support technician suspects an issue with the power cable. What common fault in power cables should the technician check for first?
Correct Answer: B
Correct Answer. B. Physical damage to the cable or its connectors Physical damage to the power cable or its connectors is a common cause of intermittent power losses in desktop computers. The technician should first inspect the cable for any signs of wear, tear, or damage to the connectors that could disrupt the power supply. Option A is incorrect because electromagnetic interference affects data transmission more than power cables. Option C is incorrect because data transmission speed is irrelevant to the performance of power cables, which are designed solely to transmit electrical power. Option D is incorrect because power cables for desktop computers do not need to be compatible with USB devices; this is unrelated to powering the desktop itself.
