Question 11.

Magnetic tapes are good storage media for

  1.    backup and low volume data
  2.    backup and high volume data
  3.    storing original but low volume data
  4.    storing original but high volume data
  5.    None of the above
 Discuss Question
Answer: Option B. -> backup and high volume data
Magnetic tape is a storage medium that uses magnetic particles to record and store data. It consists of a long and narrow strip of plastic film coated with a magnetic material. The data is stored on the tape in the form of magnetic signals, which can be read and written using a tape drive.
Magnetic tapes have been in use for several decades and have been a popular choice for backup and archival storage. Here are some reasons why magnetic tapes are suitable for backup and high volume data:
  • High capacity: Magnetic tapes have a high storage capacity and can store large amounts of data. They are available in different sizes and can store anywhere from a few gigabytes to several terabytes of data.
  • Low cost: Magnetic tapes are relatively inexpensive compared to other storage media such as hard disk drives and solid-state drives. This makes them an attractive option for backup and archival storage, where cost is a significant factor.
  • Long-term storage: Magnetic tapes are suitable for long-term storage as they have a longer lifespan compared to other storage media. They are also less prone to data corruption and can retain data for several years.
  • Reliable: Magnetic tapes are less susceptible to mechanical failures and data loss compared to other storage media. This makes them a reliable option for backup and archival storage.
In summary, magnetic tapes are suitable for backup and high volume data storage due to their high capacity, low cost, long-term storage capability, and reliability.
Some other storage media commonly used for data storage include hard disk drives, solid-state drives, optical discs, and cloud storage. Each of these storage media has its advantages and disadvantages, and the choice of storage media depends on the specific requirements of the data storage application.

  1.    a medium capacity removable disk storage system
  2.    an input device
  3.    an output device
  4.    a software
  5.    None of above
 Discuss Question
Answer: Option A. -> a medium capacity removable disk storage system
Question 17.

The type of program required for writing to CD-RWs is called

  1.    a BDF packet writer 
  2.    a VDF packet writer
  3.    a CDF packet writer
  4.    a LDE packet writer
  5.    None of these
 Discuss Question
Answer: Option B. -> a VDF packet writer
 a VDF packet writer, is the correct answer for the type of program required for writing to CD-RWs. Let's understand the different terms used in the question and the answer:
  • CD-RW: It stands for Compact Disc Re-Writable, and it is a type of optical disc that allows data to be written, read, and erased multiple times.
  • Packet Writing: It is a method of writing data to a rewritable disc in small, independent packets, rather than in a single continuous stream. This method allows the disc to be used like a hard drive, with files added, deleted, and modified as needed.
  • BDF, VDF, CDF, and LDE: These are different packet writing formats used for writing data to rewritable discs.
Now, let's see why option B, a VDF packet writer, is the correct answer:
  • VDF: It stands for Virtual Disk File, and it is a packet writing format used for writing data to CD-RWs. VDF packet writing divides the disc into small, fixed-size blocks called sectors, and data is written to these sectors in packets. The VDF format is supported by many popular packet writing programs such as DirectCD, InCD, and Drag-to-Disc.
  • BDF: It stands for Block Descriptor File, and it is a packet writing format used for writing data to DVD-RAM discs.
  • CDF: It stands for Continuous Data File, and it is a packet writing format used for writing data to CD-MO (Magneto-Optical) discs.
  • LDE: It stands for Low-Density Erase, and it is a packet writing format used for writing data to some types of DVD-RAM and DVD-RW discs.
To summarize, a VDF packet writer is the type of program required for writing data to CD-RWs using packet writing. It is important to note that different packet writing formats are used for different types of rewritable discs, and using the wrong format can lead to compatibility issues.
