Question 1

Experts estimate that hard disks using perpendicular recording will provide storage capacities about how many times greater than disks that use longitudinal recording?
A) 3
B) 7
C) 10
D) 15

Accepted Answer

Perpendicular recording stores data perpendicular to the disk surface, while longitudinal recording stores data parallel to the disk surface. This allows perpendicular recording to store more data in the same amount of space, resulting in higher storage capacities.

A) sector
B) read/write head
C) vector
D) platter

Accepted Answer

A platter is a rotating disk made of aluminum, glass, or ceramic and is coated with an alloy material that allows items to be recorded magnetically on its surface. Sectors, vectors, and read/write heads are all components found within a hard drive, but they do not match the given description.

A) RAID
B) RAS
C) NAS
D) RAN

Accepted Answer

NAS (Network Attached Storage) devices are servers connected to a network with the sole purpose of providing storage. RAID (Redundant Array of Independent Disks) is a technology used in storage devices to increase data reliability and performance. RAS (Remote Access Server) is a device that allows remote access to a network. RAN (Radio Access Network) is a type of mobile telecommunications network.

Question 8

Which of the following is an advantage of portable hard disks and removable hard disks?
A) They can transport a large number of files.
B) They can add storage space to a notebook computer or Tablet PC.
C) They can easily store large audio and video files.
D) all of the above

Accepted Answer

Portable and removable hard disks offer the benefits of transporting large files, adding storage to devices, and storing large media files, making all options correct.

Question 9

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

The term used in the question is "improve hard disk access time". The fastest way to access data is from memory chips, so using a disk cache can help improve access time by storing frequently accessed items in memory for faster retrieval. Options A, C, and D are not related to computer hardware or storage.

Question 10

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 (Redundant Array of Independent Disks) is a technology that combines multiple hard disks into a single logical unit, either for data redundancy and backup or for improved performance.

Question 11

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 component that interacts with the disk's recording surface to read and write data. It is a tiny magnet located at the tip of an actuator arm, which moves it across the surface of the platter to access different areas of the drive.

Question 12

Which of the following devices is the computer hardware that records and/or retrieves items to and from storage media?
A) concatenation
B) indexed
C) resolved
D) storage

Accepted Answer

Storage devices are hardware components that record and retrieve data from storage media.

Question 13

Access time for today's hard disks is which of the following ranges?
A) 8 - 10 KBps
B) 3 - 12 MBps
C) 3 - 12 ms
D) 5,400 - 15,000 rpm

Accepted Answer

Access time for hard disks is typically measured in milliseconds (ms), and today's hard disks generally have access times in the range of 3 to 12 ms.

Question 14

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. Optical disks use a more flexible disk with a reflective surface and grooves that hold the data in the form of tiny pits and lands. Digital disks can refer to both hard disks and optical disks, but the term usually refers to optical disks such as CDs and DVDs that store data in digital format. Indexed disks are not a common storage medium and do not typically use magnetic particles.

Question 15

Which of the following is a duplicate of a file, program, or disk that can be used in case the original is lost, damaged, or destroyed?
A) cache
B) backup
C) home site
D) baseline

Accepted Answer

A backup is a duplicate of a file, program, or disk that can be used in case the original is lost, damaged, or destroyed.

Question 16

What kind of hard disk is a hard disk that you insert and take out of a drive, and that may either be built into the system unit or external and connected via a USB or FireWire port?
A) personal
B) mini
C) USB
D) removable

Accepted Answer

A removable hard disk is designed to be easily inserted and removed from a drive, and can be either internal or external, often connecting via USB or FireWire.

Question 17

Memory (chips) accesses items in which of the following units of time?

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

The write-protect notch is a characteristic of a floppy disk, not a hard disk. Hard disks use read/write heads to access data stored in sectors and tracks, and their capacity can vary depending on the size of the disk.
