[amp_mcq option1=”RFI” option2=”EMI” option3=”EXE” option4=”FYI E. IOU” correct=”option2″]<\/p>\n
The correct answer is: B. EMI<\/strong><\/p>\n 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.<\/p>\n Floppy drives, hard drives, and even VCR tapes or cassette tapes are all sensitive to EMI. When these devices are placed near a source of magnetism, the magnetic field can cause the data on the device to be corrupted or erased. This can result in data loss or even damage to the device.<\/p>\n To avoid this, it is important to keep these devices away from sources of magnetism, such as speakers. If you must place them near a speaker, it is important to use a protective case or shield to block the magnetic field.<\/p>\n The other options are not correct. RFI stands for radio frequency interference. EXE is a file extension for executable files. FYI stands for for your information. IOU stands for I owe you.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”RFI” option2=”EMI” option3=”EXE” option4=”FYI E.
