Question 1

Which of the following is the mechanism that reads and writes items in the drive as it barely touches the disk's recording surface?
A) read/write head
B) disc index
C) input vector
D) platter notch

Accepted Answer

The read/write head is the mechanism that reads and writes items in the drive as it barely touches the disk's recording surface. The disc index, input vector, and platter notch are not involved in this process.

Question 2

Which of the following is made of aluminum, glass, or ceramic and is coated with an alloy material that allows items to be recorded magnetically on its surface?
A) sector
B) read/write head
C) vector
D) platter

Accepted Answer

The platter is the component of a hard disk drive that is made of aluminum, glass, or ceramic and is coated with an alloy material that allows items to be recorded magnetically on its surface.

Question 4

Which of the following is NOT a cloud storage provider?
A) eCloud
B) Amazon Cloud Drive
C) Box
D) Google Drive

Accepted Answer

There is no cloud storage provider named "eCloud". The other options are all well-known and popular cloud storage providers. However, the best choice depends on individual needs and preferences. Amazon Cloud Drive and Google Drive may be good choices for those who already use other Amazon or Google services. Box may be a good choice for businesses or teams that need collaboration features.

Question 5

Some computers improve hard disk access time by using which of the following, which consists of memory chips that store frequently accessed items?
A) warehouse
B) disk cache
C) base
D) home

Accepted Answer

Disk cache is a portion of random access memory (RAM) that is set aside to hold data that has recently been read from or written to the disk. This improves hard disk access time because the system can retrieve data from the cache faster than from the disk.

Question 6

Which of the following is NOT an advantage of external hard drives over internal hard drives?
A) They can transport a large number of files.
B) They can add storage space to a mobile computer.
C) They can easily store large audio and video files.
D) They leave data in the computer.

Accepted Answer

This statement is not an advantage of external hard drives over internal hard drives. Internal hard drives do leave the data in the computer, whereas external hard drives can be removed and stored separately. A, B, and C are all advantages of external hard drives over internal hard drives.

Question 7

A group of two or more integrated hard disks is referred to as which of the following?
A) pocket
B) UFC
C) RAID
D) baseline

Accepted Answer

RAID stands for Redundant Array of Independent Disks and is a technology that combines multiple hard disks into a single logical unit for better performance, data redundancy, and fault tolerance. The other options (A, B, and D) are not related to integrated hard disks.

Question 8

Which of the following is a device that reads from and writes on memory cards?
A) access stick
B) reader/writer
C) access port
D) restorer

Accepted Answer

A device that reads from and writes on memory cards is commonly referred to as a reader/writer.

Question 9

Storage devices access items in which of the following units of time?
A) nanoseconds
B) macroseconds
C) milliseconds
D) petaseconds

Accepted Answer

Storage devices typically access items in milliseconds, which is a thousandth of a second. Nanoseconds are too fast for most storage devices to access, while macroseconds and petaseconds are too slow.

Question 10

What is the term for the case that contains the same adapters found on a motherboard with which to connect the internal hard drive?
A) drive manager
B) vector
C) enclosure
D) platter

Accepted Answer

The term for the case that contains the same adapters found on a motherboard with which to connect the internal hard drive is enclosure. A drive manager is software used to manage and optimize hard drives. Vector refers to a mathematical concept in computer graphics. Platter is a component of a hard drive that stores data using magnetic fields.

Question 11

The inflexible, circular platters on which kind of disks use magnetic particles to store data, instructions, and information?
A) hard
B) digital
C) optical
D) indexed

Accepted Answer

Hard disks use inflexible, circular platters with magnetic particles to store data, instructions, and information.

Question 12

Which of the following is true of SSDs compared to traditional hard disks?
A) SSDs have lower storage capacities.
B) SSDs generate more heat.
C) SSDs have faster transfer rates.
D) SSDs have a shorter life.

Accepted Answer

SSDs have faster transfer rates compared to traditional hard disks.

Question 13

Which of the following devices is the computer hardware that records and/or retrieves items to and from a flash drive or external hard drive, for example?
A) concatenation
B) indexed
C) resolved
D) storage

Accepted Answer

The device that records and retrieves items to and from a flash drive or external hard drive is a storage device. Concatenation, indexed and resolved do not refer to such a device.

Question 14

Which of the following is NOT a common type of memory card?
A) SDXC
B) Memory Stick PRO Duo
C) MX6
D) SDHC

Accepted Answer

SDXC, Memory Stick PRO Duo, and SDHC are all common types of memory cards. MX6, however, is not a common type of memory card.

Question 15

Memory (chips) accesses items in which of the following units of time?
A) nanoseconds
B) microseconds
C) milliseconds
D) seconds

Accepted Answer

Memory chips are designed to access data at very high speeds. It is measured in nanoseconds because most memory chips can access data in less than a nanosecond, which means they can access millions of pieces of data in a single second. Therefore, option A is the best choice.

Question 16

Users subscribe to a cloud storage service, like the kind advertised in the accompanying figure, to do all of the following EXCEPT to ____.
A) save time by storing large files instantaneously
B) allow others to access files
C) store offsite backups of data

Accepted Answer

Capacity refers to the amount of data a storage medium can hold.

Question 19

What kind of storage is an Internet service that provides storage to computer or mobile users?
A) encrypted
B) shared
C) cloud
D) net

Accepted Answer

The term used to describe an Internet service that provides storage to computer or mobile users is "cloud storage." Cloud storage refers to a network of remote servers that allow users to store, manage, and access data over the Internet instead of on a physical hard drive. Encrypted storage refers to storage that has been coded or scrambled to protect the data from unauthorized access. Shared storage refers to storage that is accessible by multiple users or devices. Net storage is not a commonly used term in the industry.

Question 20

Which of the following is not a characteristic of a hard disk?
A) write-protect notch
B) read/write head
C) sectors and tracks
D) capacity

Accepted Answer

A write-protect notch is a characteristic of a floppy disk, not a hard disk. Hard disks have read/write heads, organized into sectors and tracks, and have varying capacities.
