Computer Storage Devices Review

1. The device interface that will allow you to connect up to 7 devices to a single controller card through 1 ribbon cable is called the _________ interface.
   1. IDE
   2. SCSI
   3. EISA
   4. EIDE

2. Hard Disk drives have which of the following characteristics?
   1. Access speeds in the 8 to 12 ms range.
   2. One or more magnetic coated surfaces.
   3. Can be installed as a "master" or "slave" drive.
   4. All of the above are true.

3. Of the current storage devices available, which of the following will allow you to have 1 GB or more storage space?
   1. Floppy drive
   2. Hard Disk drive
   3. ZIP drive
   4. Bernoulli drive

4. The interface which is most common in today's PCs and which only allows 2 devices per ribbon cable is the
   1. IDE
   2. SCSI
   3. EIDE
   4. EISA

5. A "Bernoulli" drive differs from a 3 1/2 inch floppy drive primarily in their
   1. size, capacity, and access speeds.
   2. size and speed.
   3. 'bernoulli drives are used for backup.
   4. a 'bernoulli' is slower than a floppy drive, but holds 10 times more data.

6. The current 'removable' storage devices that makes high capacity data (1 GB+) data devices efficent are called
   1. ZIP drives and SyJET drives.
   2. Bernoulli and ZIP drives.
   3. JAZ and SyJET drives.
   4. SyJET and DITTO drives.

7. The Access time (seek time) for the 'best' removable cartridge type storage devices are approximately
   1. 18 ms.
   2. nearly equivalent to hard disk technology - around 10-12 ms.
   3. only about 50% as quich as a hard drive.
   4. slower than a CD-ROM device.

8. Tape drives, when compared to most other 'mass' storage devices suffer in comparison because
   1. a tape drive has a low storage capacity.
   2. a tape drive has a very slow access time.
   3. tape drives are more cumbersome.
   4. All of the above.

9. You would normally purchase a tape drive for which of the following reasons?
   1. high-volume data storage.
   2. large data bases with low access rates.
   3. for transferring data between PCs.
   4. for backup of a system's hard drives.

10. "Portability" of data can be accomplished between remote locations best by using the Internet; however, if you travel and want to hand-carry large volumes of information, you could purchase a
    1. external floppy drive with a SCSI interface.
    2. a recordable CD-ROM device.
    3. a tape drive.
    4. an external "JAZ" or "SyJet" drive with a parallel interface.
