Q21. Which of the following is an example of a hybrid secondary storage device?
a) Hard disk drive
b) Solid-state hybrid drive (SSHD)
c) Magnetic tape
d) Optical disk
Show Answer
Correct Answer: b) Solid-state hybrid drive (SSHD)
Explanation: A hybrid secondary storage device combines the features of two or more storage technologies to provide the benefits of both. An example of a hybrid secondary storage device is a solid-state hybrid drive (SSHD), which combines the high-speed performance of an SSD with the large storage capacity of an HDD.
Q22. Which of the following is a type of optical disk that can store high-definition video?
a) CD-ROM
b) CD-R
c) DVD
d) Blu-ray
Show Answer
Correct Answer: d) Blu-ray
Explanation: Blu-ray is a type of optical disk that can store high-definition video, as well as other types of data. It uses a blue-violet laser to read and write data, which allows for higher storage capacities and faster data transfer rates compared to CDs and DVDs.
Q23. What is the primary difference between a Hard Disk Drive (HDD) and a Solid State Drive (SSD)?
a) HDDs use magnetic storage, while SSDs use optical storage
b) HDDs have moving parts, while SSDs have no moving parts
c) HDDs are faster and more reliable than SSDs
d) SSDs have a higher storage capacity than HDDs
Show Answer
Correct Answer: b) HDDs have moving parts, while SSDs have no moving parts
Explanation: The primary difference between a Hard Disk Drive (HDD) and a Solid State Drive (SSD) is that HDDs have moving parts, while SSDs have no moving parts. HDDs use magnetic storage and rely on spinning disks and a moving read/write head, whereas SSDs use NAND-based flash memory. This makes SSDs faster, more reliable, and more energy-efficient than HDDs.
Q24. Which of the following is a type of memory card?
a) CompactFlash (CF)
b) CD-ROM
c) Magnetic tape
d) Hard Disk Drive (HDD)
Show Answer
Correct Answer: a) Compact Flash (CF)
Explanation: CompactFlash (CF) is a type of memory card used for storing data in portable electronic devices such as digital cameras, audio recorders, and smartphones. Memory cards are small, removable storage devices that use flash memory to store data.
Q25. What is the main advantage of online storage compared to near-line and offline storage?
a) Lower cost
b) Faster data access
c) Greater storage capacity
d) Better data security
Show Answer
Correct Answer: b) Faster data access
Explanation: The main advantage of online storage compared to near-line and offline storage is faster data access. Online storage systems store data on devices that are directly connected to the computer or network, allowing for immediate access to the data. Near-line storage systems require some delay in accessing the data, while offline storage systems require manual intervention to access the data.
Q26. What is the primary function of a Zip disk?
a) To store and manage multiple CD-ROMs in a single device
b) To provide a portable, high-capacity storage solution
c) To store data in a non-volatile manner
d) To provide random access to data
Show Answer
Correct Answer: b) To provide a portable, high-capacity storage solution
Explanation: A Zip disk is a type of magnetic disk that provides a portable, high-capacity storage solution. It was popular in the 1990s and early 2000s as a means of transferring large files between computers and for backing up data. Zip disks have since been largely replaced by more modern storage solutions, such as USB flash drives and cloud storage.
Q27. Which of the following is a type of magnetic disk?
a) CD-ROM
b) Magnetic tape
c) Hard Disk Drive (HDD)
d) Solid State Drive (SSD)
Show Answer
Correct Answer: c) Hard Disk Drive (HDD)
Explanation: A Hard Disk Drive (HDD) is a type of magnetic disk used for data storage. It uses magnetic storage and relies on spinning disks and a moving read/write head to store and access data. HDDs are widely used in computers and other data storage systems due to their high storage capacity and relatively low cost.
Q28. What is the primary function of a CD-ROM Jukebox?
a) To store and manage multiple CD-ROMs in a single device
b) To play music from multiple CD-ROMs simultaneously
c) To increase the storage capacity of a single CD-ROM
d) To provide random access to data on multiple CD-ROMs
Show Answer
Correct Answer: a) To store and manage multiple CD-ROMs in a single device
Explanation: A CD-ROM Jukebox is a storage device that can store and manage multiple CD-ROMs in a single unit. It allows users to access data from multiple CD-ROMs without having to manually swap discs, making it an efficient solution for managing large collections of optical media.
Q29. What is a Winchester disk?
a) A type of magnetic disk
b) A type of optical disk
c) A type of solid-state drive
d) A virtual disk created in a computer’s RAM
Show Answer
Correct Answer: a) A type of magnetic disk
Explanation: A Winchester disk is a type of magnetic disk that was an early version of the modern hard disk drive. It was named after the IBM 3340 Winchester disk drive, which was introduced in 1973. The term “Winchester” was used to describe the sealed disk and head assembly, which improved reliability and reduced contamination compared to earlier disk drive designs.
Q30. What is a Memory card?
a) A type of magnetic disk
b) A type of optical disk
c) A type of solid-state drive
d) A small, removable storage device that uses flash memory
Show Answer
Correct Answer: d) A small, removable storage device that uses flash memory
Explanation: A Memory card is a small, removable storage device that uses flash memory to store data. Memory cards are commonly used in portable electronic devices, such as digital cameras, smartphones, and audio recorders, to provide additional storage capacity and easy data transfer between devices.
