Question 1

What term is used to measure machine cycle time?

Accepted Answer

A

Question 2

Where are the CPU and memory of a computer located?

Accepted Answer

The CPU and memory of a computer are located in the system unit. The system unit includes the motherboard, which connects to the CPU, memory, and other components such as storage drives and expansion cards.

Question 3

The selection of computer hardware requires understanding of the organization's relationship to two things.The first is its information system.What is the other?

Accepted Answer

The other thing that must be understood when selecting computer hardware is the organization's needs. This includes its current needs and anticipated future needs in terms of storage, processing power, and other hardware specifications. Understanding the organization's needs ensures that the hardware selected will effectively support its operations and enable growth.

Question 4

What is another name for secondary storage?

Accepted Answer

Secondary storage is also known as permanent storage because it retains data even when power is turned off, unlike primary storage such as main memory and cache memory. Backup storage refers to a separate copy of data kept in case the original is lost or damaged.

Question 5

Which of the following terms means that data must be accessed in the order in which it is stored?

Accepted Answer

Sequential access requires data to be accessed in the order it is stored, while direct and indirect access allow random access to data. Volatile access refers to the volatility of memory, not the order in which data is accessed.

Question 6

Gillian recently bought a computer that allows her to download a movie and play a game simultaneously.What is the term used for this type of capability?

Accepted Answer

The answer of Gillian recently bought a computer that allows...

Question 7

Company ABC needs a large volume of disk space to be used by employees in different locations.What type of storage solutions would help them?

Accepted Answer

A storage area network (SAN) is a high-speed network that connects storage devices to servers. It allows multiple servers to access the same storage devices, which can be located in a different location. This makes it an ideal solution for companies that need a large volume of disk space to be used by employees in different locations.

Question 8

What type of data storage does RAID storage devices provide for organizations?

Accepted Answer

RAID (Redundant Array of Inexpensive Disks) storage devices provide fault-tolerant data storage, which means that even in the event of a disk failure, the data can still be accessed and recovered. This is important for organizations that rely on important data and cannot afford to lose it due to hardware failure. RAID also offers improved performance and faster data access, but this is not its primary function.

Question 9

What advanced optical disk technology, still in development, would store more data than even the Blu-ray optical disk system?

Accepted Answer

The holographic versatile disk is an advanced optical disk technology that uses holographic storage to store significantly more data than the Blu-ray system. It has the potential to store up to one terabyte of data on a single disc.

Question 10

Susan is doing her taxes using Excel.She has opened several files and is swapping data from one file to another.What type of memory is enabling Susan to do the swapping efficiently?

Accepted Answer

Cache memory is a type of high-speed memory that helps speed up data access by storing frequently accessed data, allowing for efficient data swapping between files.

Question 11

In computers, how many bits usually form a byte of data or a single character?

Accepted Answer

A byte is typically composed of 8 bits, which can represent a single character or a unit of data.

Question 12

"Which of the following is a primary element of a central processing unit?"

Accepted Answer

The control unit is a primary element of a central processing unit (CPU) because it manages and directs the flow of data within the CPU and communicates with other computer components. The memory unit and hard drive unit are secondary storage components, while the input/output unit handles communication between the computer and external devices.

Question 13

What activity uses several computers, often owned by many people or different organizations, working in a coordinated manner to solve a common problem?

Accepted Answer

Grid computing involves multiple computers owned by different entities, often working together towards a common goal or to solve a common problem. This can include tasks such as scientific research, data analysis, or large-scale simulations. Cloud computing involves accessing shared resources through the internet, rather than coordinating the use of multiple computers. Parallel computing involves using multiple processors within a single computer to perform tasks simultaneously. Virtual computing involves creating a virtualized environment within a single computer or network to simulate multiple systems.

Question 14

What computer components, also called hardware, perform the input, processing, storage, and output activities of the computer?

Accepted Answer

Physical components perform the input, processing, storage, and output activities of the computer. Examples of physical components include the central processing unit (CPU), motherboard, random access memory (RAM), hard disk drive (HDD), monitor, keyboard, and mouse.

Question 15

What type of memory's contents is NOT lost if the power is turned off?

Accepted Answer

Nonvolatile memory retains its contents even when power is turned off, unlike the other types of memory listed.

Question 16

Which technology provides a fast and high volume of storage to large organizations??

Accepted Answer

A storage area network (SAN) is a technology that provides fast and high volume storage to large organizations. SANs use dedicated high-speed networks to connect storage devices to servers, allowing multiple servers to access the same pool of storage resources. This enables organizations to store and manage large amounts of data efficiently and securely. RAID storage devices can also provide high volume storage, but they may not always be as fast as SANs, and they typically require more maintenance and monitoring. Digital video disks and virtual tapes are not typically used for high volume storage in large organizations.

Question 17

What type of storage method is used for less frequently needed data and appears to be stored entirely on tape cartridges?

Accepted Answer

Virtual devices often simulate storage on tape cartridges for less frequently accessed data, providing a cost-effective solution for archival storage.

Question 18

How does secondary storage compare to main memory?

Accepted Answer

Secondary storage devices, such as hard disk drives and solid-state drives, are generally slower than main memory or primary storage devices like RAM. This is because secondary storage devices are typically used for long-term storage and retrieval of data, while primary storage is used for quick access to data that is currently being processed by the computer's CPU.

Question 19

Katarina, a graphic designer, purchased a computer with the capability to effectively manage her graphical needs to manipulate images.What type of processor would she need?

Accepted Answer

A graphics processing unit (GPU) is specifically designed to handle the graphical needs of a computer, making it the ideal choice for a graphic designer. The other options listed (graphic multiprocessor, multicore, and multithread) may also be beneficial for graphic design, but a GPU is the most important component for managing graphical needs.

Question 20

Sharon does accounting work for many clients and needs her computer to back up data as she makes changes to the files.What type of mechanism would do that?

Accepted Answer

Disk mirroring (also known as RAID 1) is a mechanism that maintains an identical copy of data on two separate hard drives. Whenever Sharon makes changes to the files, disk mirroring will automatically replicate those changes onto the backup drive, providing reliable protection against data loss.
