1)All components comprising a computer system except for the                                     , are considered peripherals.

1. 1. CPU
   2. CPU and memory
   3. CPU, memory, and power source

4. In technical specifications for flash memory, the read/write block is called a
   1. page.
   2. lump.

5. On a modern hard disk, what is the typical size of a block of data?
   1. 64 bytes
   2. 128 bytes
   3. 512 bytes
   4. 1024 bytes

6. With the hard drive read/write head in a fixed position, it traces out a circle on the disk surface as the disk rotates; this circle is known as a
   1. page.
   2. block.
   3. track.
   4. cluster.

7. When a disk drive has multiple platters, the heads on each surface all line up. The set of tracks for all the surfaces form a geometric shape similar to a
   1. bottle.

   3. sphere.
   4. cylinder.

8. In a disk drive where the drive motor turns at constant angular velocity, which is true of the linear velocity?
   1. inner tracks move the fastest
   2. outer racks move the fastest
   3. middle tracks move the fastest
   4. all tracks move at the same speed

9. The time it takes for the hard-disk read/write head to move from one track to another is called
   1. latency.                                                                                  .
   2. seek time.
   3. flight time.
   4. arrival time.

10. Once the hard-disk read/write head is located over the desired track, the read/write operation must wait for the disk to rotate to the beginning of the correct sector. This time is called

1. seek time.
2. arrival time.
3. transfer time.
4. rotational latency time.

11. The time required to transfer one block of data is called as the

1. seek time.
2. arrival time.
3. transfer time.
4. rotational latency time.

12. What system performance attribute is most increased by using a redundant array of independent disks (RAID)?

1. System reliability
2. System accessibility
3. System serviceability
4. System maintainability

13. In a mirrored array with 4 disks, each of the disks stores exactly the same data. The access time for a multiblock read is reduced by a factor of about                     .

1. two
2. four
3. eight
4. sixteen

14. A special fault-tolerant computer system uses an array of 3 disks. The following logic is used to detect errors: If the data from all three disks is identical, then it is safe to assume that the integrity of the data is acceptable. If the data from one disk differs from the other two, then accept the data where both match and flag the other as an error. This logic is known as

1. disk logic.
2. majority logic.
3. difference logic.
4. greater-part logic.

15. A mirrored array requires a minimum of                                disk drives.
    1. two
    2. three
    3. four
    4. five

16. The technique used for storage and retrieval in an LTO formatted data cartridge is called

1. data torrent.
2. LTO tasking.

3. data continuity.
4. data streaming.

17. In terms of the ability to see detail in a display, a more interesting measure of resolution is the

1. pixel count.
2. pixel density.
3. pixel intensity.
4. pixel concentration.

18. Displays that use 256 (Red) × 256 (Green) × 256 (Blue) different colors on the screen is sometimes described as a

1. 1. true color system.
   2. virtual color system.
   3. ultra high density system.
   4. high density color system.

19. The number of bits used to represent colors in an image is known as

1. color depth.
2. color length.
3. color strength.
4. color intensity.

20. A proprietary standard, developed by Microsoft to render 2-D and 3-D objects is known as

1. OpenGL.
2. DirectX.
3. ActiveX.
4. OpenSource.

21. An International standard maintained by a non-profit consortium to render 2-D and 3-D objects is known as

1. OpenGL.
2. DirectX.
3. ActiveX.
4. OpenSource.

22. A key to the efficient operation of a GPU is the ability to dispatch instructions to the CPU cores in rapid succession, a process commonly called

1. flowing.
2. cramming.
3. smoothing.
4. streaming.

23.                          is a standard GPU programming interface for general-purpose parallel programming that is implemented on a number of GPUs from different vendors.

1. OpenX
2. DirectX
3. OpenCL

24. With the exception of the Cell Engine, current GPUs are generally based on maximizing the number of operations that can take place at the same time, or                                      .

1. serialization
2. concurrency
3. parallelization

4. synchronization

25. One of the main disadvantages of active matrix LCDs is that they

1. consume a lot of power.

1. QR software compares images to a list of known images.
2. QR software uses 2D mapping technology to read the QR code.
3. QR software requires the image capture device be perpendicular to the QR code.
4. QR software positions and sizes the image with the aid of large squares in three corners and a smaller square set in from the fourth corner.
