T/F: A storage medium is volatile; that is, items stored on it remain intact even when you turn off a computer or mobile device.
False: A storage medium is NONVOLATILE; that is, items stored on it remain intact even when you turn off a computer or mobile device.
T/F: An active RFID tag contains a battery than runs the chip's circuitry and broadcasts a signal to the RFID reader; because they are so small, they can be embedded in skin.
False: An active RFID tag contains a battery than runs the chip's circuitry and broadcasts a signal to the RFID reader; BECAUSE THEY CONTAIN A BATTERY, THEY ARE TOO BIG TO BE EMBEDDED IN SKIN.
T/F: Because of current standards, head crashes no longer occur.
False: EVEN WITH THE current standards, head crashes STILL OCCASIONALLY OCCUR.
T/F: Mini discs require a separate mini disc drive; that is, they do not work in standard-sized optical disc drives.
False: Mini discs DO WORK in standard-sized optical disc drive
T/F: Storage devices can be categorized as input or output devices.
False: Storage devices FUNCTION AS INPUT, BUT ARE CATEGORIZED AS STORAGE DEVICES.
T/F: When you are finished using a USB flash drive, simply remove it from the USB port.
False: When you are finished using a USB flash drive, EJECT, AND SAFELY REMOVE FROM USB PORT.
