Question 1

A(n)____________________ stores copies of data or programs that are located on the hard drive and that might be needed soon in memory chips in order to avoid having to retrieve the data or programs from the hard drive when they are requested.

Accepted Answer

The answer of A(n)____________________ stores copies of data or programs...

Question 2

A ____ is a separate piece of hardware containing multiple high-speed hard drives.

Accepted Answer

A storage server is a separate piece of hardware that contains multiple high-speed hard drives. It is designed to provide centralized storage and editing capabilities for shared files and data.

Question 3

Smart cards and holographic drives are examples of ____ systems.

Accepted Answer

Smart cards and holographic drives are examples of storage systems. Smart cards are small portable devices that contain an embedded microchip to store information. Holographic drives use holographic storage technology to store data in three dimensions, increasing the amount of information that can be stored on a disc. Both examples involve the storage of data, making option D the correct answer.

Question 4

Case 3-2
Rodney owns a computer that he uses to work,keep in touch with friends and family,watch movies,listen to music,and use the Internet.
-If Rodney wants to record music files onto a CD,he needs to make sure that his operating system has CD-____ capabilities.

Accepted Answer

To record music files onto a CD, Rodney would need to use a CD burner or writing software that allows him to copy files onto a blank CD. This process is commonly referred to as CD burning. Therefore, the correct answer is B) burning.

Question 5

To record data,holographic storage systems split the light from a blue laser beam into ____ beams.

Accepted Answer

Holographic storage systems split the light from a blue laser beam into two beams in order to record data.

Question 6

____ provide(s)a method of storing data on two or more hard drives that work in combination to do the job of a larger drive.

Accepted Answer

RAID (redundant arrays of independent disks) provide(s) a method of storing data on two or more hard drives that work in combination to do the job of a larger drive. RAID can increase reliability, data access speed, and/or storage capacity depending on the specific type of RAID configuration used. Storage Area Networks (SANs) and Network Attached Storage (NAS) are different types of network storage solutions that may use RAID configurations, but they are not directly related to the concept of RAID itself. Holographic Storage is a potential future technology that could provide very high storage densities, but it is not directly related to the concept of RAID either.

Question 7

____________________ data refers to data stored on a device's storage medium that will still be there after you have powered off and on your device.

Accepted Answer

The answer of ____________________ data refers to data stored on...

Question 8

Case 3-1
Dan is a small business owner who depends on his computer to keep track of customer and sales data.He is investigating storage options because it is critical for him to ensure that his data is safe in the event of a computer failure.
-A friend of Dan suggested to him that he can use an external hard drive for his data storage and backup needs.To use an external hard drive,Dan should make sure that his computer has an available USB or ____ port.

Accepted Answer

FireWire is a type of port that can be used to connect external hard drives to a computer, similar to USB ports.

Question 9

Case 3-2
Rodney owns a computer that he uses to work,keep in touch with friends and family,watch movies,listen to music,and use the Internet.
-If Rodney wants to be able to record,erase,and overwrite the files on a CD,he should get a ____.

Accepted Answer

CD-RW stands for Compact Disc - Rewritable, which means that the disc can be recorded, erased, and overwritten multiple times. CD-R, on the other hand, stands for Compact Disc - Recordable, which means that the disc can only be recorded once and cannot be erased or overwritten. CD-HD and CD-BD are not valid types of CDs. Therefore, the best choice for Rodney would be CD-RW.

Question 10

In addition to tracks,sectors,and clusters,hard drives also have ____________________.

Accepted Answer

The answer of In addition to tracks,sectors,and clusters,hard drives also...

Question 11

Case 3-2
Rodney owns a computer that he uses to work,keep in touch with friends and family,watch movies,listen to music,and use the Internet.
-Rodney wants to be able to easily carry files with him wherever he goes but he also has a tendency to lose things.Knowing this,he should probably save those files on a ____ drive which he can then attach to his backpack.

Accepted Answer

A USB flash drive is a small, portable device that can easily be attached to a backpack or carried in a pocket. This makes it a good choice for someone like Rodney who wants to carry files with him wherever he goes. Additionally, since Rodney has a tendency to lose things, a USB flash drive would be a better choice than a CD or hard drive, which are larger and more easily misplaced. A fusion drive is a hybrid storage device that combines a hard drive with flash storage, but this would not be necessary for Rodney's needs.

Question 12

A(n)____________________ hard drive is a hard drive that contains both a large amount of flash memory and magnetic hard disks.

Accepted Answer

The answer of A(n)____________________ hard drive is a hard drive...

Question 13

To read data, the reference beam projects the hologram containing the requested data onto a ____ that reads the entire data page at one time.

Accepted Answer

The detector reads the hologram containing the requested data projected by the reference beam.

Question 14

Case 3-1
Dan is a small business owner who depends on his computer to keep track of customer and sales data.He is investigating storage options because it is critical for him to ensure that his data is safe in the event of a computer failure.
-As Dan is very concerned about maintaining the security of his business data,he should look for an external hard drive that comes with built-in ____.

Accepted Answer

Encryption is the best option for maintaining the security of business data, as it provides a way to prevent unauthorized access to the data even if the external hard drive is lost, stolen, or accessed by someone without proper authorization. Zipping and sequential access are not relevant to security concerns, and holographic technology is not commonly used for external hard drives.

Question 15

RAID 0 uses disk ____,which spreads files over several disk drives.

Accepted Answer

RAID 0 uses disk striping, which spreads data over multiple drives to improve performance. This allows for faster read and write speeds as the workload is distributed across multiple drives. However, RAID 0 does not provide any fault tolerance, meaning that if one drive fails, all data may be lost.

Question 16

____ devices are high-performance storage servers that are individually connected to a network to provide storage for the computers connected to that network.

Accepted Answer

NAS devices are specifically designed for high-performance storage capabilities and are connected to a network to provide storage for computers on that network. Super network storage and holographic storage are not terms commonly used in the industry to refer to storage solutions, and while RAID can provide redundancy for data storage, it is a technology used to combine multiple hard drives into a single logical unit, not necessarily designed solely for use over a network.

Question 17

One technology for 3D storage systems that,after many years of research and development,is now a reality is ____.

Accepted Answer

After many years of research and development, holographic storage is now a reality for 3D storage systems.

Question 18

Some smart cards today store ____ data-such as the characteristics of a fingerprint-in the card and use that data to ensure the authenticity of the card's user before authorizing the smart card transaction.

Accepted Answer

Biometric data refers to unique physical characteristics of an individual, such as fingerprints, that can be used for identification purposes. Storing biometric data on a smart card adds an extra layer of security to the authentication process, ensuring that the user is who they claim to be before allowing a transaction to take place. Holographic, optical, and biomagnetic data do not typically refer to biometric characteristics and are not commonly used for authentication purposes in smart cards.
