Lets Test Your Knowledge With Some Magnetic Storage - Quiz

Objective questions regarding the issue

Questions and Answers

1.

True or false: the physical components of a magnetic disk are aluminum-based sector and cylinder head.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The physical components of a magnetic disk are indeed aluminum-based sector and cylinder head. These components are responsible for storing and retrieving data on the disk. The sector is a small part of the disk that holds a specific amount of data, while the cylinder head is the mechanism that reads and writes data on the disk. These components work together to allow the magnetic disk to function properly.

True or false: The surface of a magnetic disc is organized by the quadratic tracks are concentric wire combination
- A.
  
  True
- B.
  
  False
Correct Answer
B. False
3.

True or false: Formatting is burning (writing) magnetically successive sectors that make up each of the tracks on a disk or diskette, thus leaving them magnetized.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Formatting is the process of preparing a disk or diskette for data storage by dividing it into tracks and sectors. During formatting, each sector is magnetically marked as either empty or occupied. This process involves burning (writing) data onto the sectors, which leaves them magnetized. Therefore, the statement that formatting is burning magnetically successive sectors on a disk or diskette, thus leaving them magnetized, is true.

True or false: Recording is achieved as a audio recorder by the action of a magnetic field of reversible polarity (NS or SN), which magnetizes the track that field acting on it.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Recording is achieved as an audio recorder by the action of a magnetic field of reversible polarity (NS or SN), which magnetizes the track that the field is acting on. This means that the statement is true.

Which company developed the CD - ROM?
- A.
  
  Time warner
- B.
  
  Ned
- C.
  
  Sony y Phillips
Correct Answer
C. Sony y pHillips

Explanation
Sony and Phillips developed the CD-ROM. The CD-ROM, which stands for Compact Disc Read-Only Memory, is a type of optical disc storage medium. It was jointly developed by Sony and Phillips in the early 1980s. The CD-ROM revolutionized the way data was stored and accessed, allowing for large amounts of information to be stored on a single disc. This technology paved the way for the development of other optical disc formats, such as DVD and Blu-ray.

In handling errors in a DVD ...
- A.
  
  Even parity is used
- B.
  
  Bits PI (Parity Inner) and are used PO (Parity Outter)
- C.
  
  There must always be the same number of bits to bit-PO PI.
Correct Answer
B. Bits PI (Parity Inner) and are used PO (Parity Outter)
7.

The HD-DVD ...
- A.
  
  It was developed, among other companies, Philips
- B.
  
  I could read in a PS3 and an XBOX 360.
- C.
  
  He lost the battle against Blu-Ray.
Correct Answer
C. He lost the battle against Blu-Ray.

Explanation
The given information states that the HD-DVD was developed by Philips and could be read in a PS3 and an XBOX 360. However, it lost the battle against Blu-Ray. This suggests that despite its development and compatibility with popular gaming consoles, HD-DVD was ultimately defeated by the Blu-Ray format.

The capacity of a DVD with respect to a CD ...
- A.
  
  It is enhanced by a larger disk.
- B.
  
  It is enhanced by use of a greater portion of the disk.
- C.
  
  It is enhanced by a higher density of data.
Correct Answer
C. It is enhanced by a higher density of data.

Explanation
The capacity of a DVD with respect to a CD is enhanced by a higher density of data. This means that more information can be stored on the same physical disk space, allowing for a larger amount of data to be stored on a DVD compared to a CD. The higher density of data is achieved through advancements in technology and the ability to store information in a more compact and efficient manner.

9.

What is the capacity of a Blu-Ray?
- A.
  
  About 50 GB double layer.
- B.
  
  25 GB if it is a single layer.
- C.
  
  The same as a DVD ..
Correct Answer(s)
A. About 50 GB double layer.
B. 25 GB if it is a single layer.

Explanation
Blu-Ray discs have a capacity of about 50 GB for double layer discs and 25 GB for single layer discs. This means that a double layer Blu-Ray disc can hold approximately 50 gigabytes of data, while a single layer disc can hold around 25 gigabytes. The capacity of a Blu-Ray disc is greater than that of a DVD.
