Answers

  1. D. In fact, just about all recordable media should be stored in a cool and dry location, although some are less affected by the environment than others. See “Storing data on tape.”

  2. B. Material Safety Data Sheets contain information on all aspects of using, handling, and storing chemical products. Take a look at “Using the right cleaning supplies.”

  3. D. These three keys open up a slot on the end of the keyboard through which the dirt chunks can fall out. Check out “The keyboard.”

  4. B. The monitor glass carries quite a charge of static electricity, and cleaning it when it is on, especially with a wet solution or cloth, can light up your life. Look at “The monitor.”

  5. C. Before you do anything to a hard drive, back it up. Then you can scan it for surface defects and optimize it by defragging it. Review “The hard drive.”

  6. C. Many viruses, like the infamous MELISSA.VBX virus, are transmitted as attachments to e-mail messages. See “Viruses and how they spread.”

  7. B. A rather nasty danger lurks inside the monitor in the form of a very large capacitor that is just looking for a way to discharge its thousands of volts of stored electricity to the first grounded entity that it can find. Don’t let it be you! Check out “The monitor.”

  8. A & C. Both an incremental backup and a differential backup copy files that have been updated (meaning written to and saved) since the last backup was created. Take a look at “Creating a data backup.”

  9. D. Each virus program has a digital signature that uniquely identifies it. See “Playing hide-and-seek with viruses.”

  10. C. The contacts of memory modules and expansion cards should be cleaned periodically with contact cleaner to remove any oxidation that may have accumulated. Review “Using the right cleaning supplies.”
