Maintenance tasks like defragmenting a disk or scanning a hard drive for errors are part of a software maintenance routine.

6. A scientific expedition team is using laptops for their work. The temperatures where the scientists are working range from -13 degrees Fahrenheit (-25 degree Celsius) to 80 degrees Fahrenheit (27 degrees Celsius). The humidity level is around 40 percent. Noise levels are low, but the terrain is rough and winds can reach 45 miles per hour (72 kilometers per hour). When needed, the scientists stop walking and enter the data using the laptop. Which condition is most likely to adversely affect a laptop that is used in this environment?

   • the rough terrain
   • the wind
   • the humidity
   • the temperature
     

     Answers Explanation & Hints: Even though laptops are normally manufactured to operate within a wide range of temperatures, the lower temperature is below freezing and not an optimal environment.
