EMI

ESD

C.
Broadcast storm

D.
Surge

Explanation:
If the power cable runs along with the computer network cable, radiation from the power cable,
known as electromagnetic interference (EMI) , may be inducted into the computer network cable
affecting the signals that pass through it. Answer option B is incorrect. ESD stands for Electrostatic
discharge. The static electricity that we generate everyday creates ESD. If you walk across a carpet
and touch someone, you experience a mild shock. Electrostatic discharge occurs when the
electrostatic charge is transferred
from one charged entity to another entity sensitive to that charge.To minimize Electrostatic
discharge (ESD) problems, consider wearing a wrist strap when you are working with computer
components. A wrist strap is a wire with a watchband-style strap at one end and a plug or clip on the
other end. The wrist strap plug or clip is connected to the ground or to the piece of equipment being
worked on.
Answer option D is incorrect. Surge is a momentary voltage variation (+/- 170 volts) that lasts from
one microsecond to a few milliseconds. Turning on and off large inductive electrical devices such as
air conditioners and refrigerators can cause a surge. Answer option C is incorrect. Broadcast storm is
a situation in which one or more network devices send jabber packets constantly, thereby
increasing the traffic. A faulty network interface card (NIC) that sends jabber packets can be
detected by the network monitor software. A faulty NIC can cause a broadcast storm on the
network. Broadcast storms caused by a faulty network interface card can be resolved by disabling or
replacing the card.
