True/False
Indicate on scantron whether the sentence or statement is true or false.
1. When a user issues a command to start application software, the operating system locates the program in
memory and loads it into storage.
2. Instead of, or in addition to access time, some manufacturers state a storage device’s transfer rate because it
affects access time.
3. A typical floppy disk can store up to 500 double-spaced pages of text, several digital photographs, or a small
audio file.
4. Users who seldom work with floppy disks can purchase their computers without an internal floppy disk drive
and opt for an external floppy disk drive instead.
5. On a floppy disk, if the write-protect notch is open, the drive can write on the floppy disk.
6. The system unit on most desktop and notebook computers contains at least one hard disk.
7. A typical hard disk has multiple platters stacked on top of one another.
8. A hard disk’s platters typically continue to spin even after power is removed from the computer.
9. A hard disk platter’s spinning motion creates a cushion of air above the read/write head, which ensures that
the read/write head makes contact with the platter surface instead of floating above the platter.
10. The average hard disk access time is at least seven times slower than the average floppy disk drive.
11. External hard disks have storage capacities up to 120 GB or higher.
12. When music is stored on a DVD, it includes surround sound and has a much better quality than that of an
audio CD.
13. Miniature hard disks are magnetic media and operate like their desktop-sized counterparts — just on a smaller
scale.
14. Depending on the device, manufacturers claim miniature mobile storage media can last from 10 to 100 years.
15. When a user purchases digital cash, the amount of money is added to the user’s bank account.
