Q41. Which of the following is an example of a sequential access storage device?
a) Hard disk drive
b) SSD
c) Magnetic tape
d) RAM
Show Answer
Correct Answer: c) Magnetic tape
Explanation: A sequential access storage device reads and writes data in a linear sequence. Magnetic tape is an example of a sequential access storage device, as data is stored and accessed sequentially along the length of the tape.
Q42. What is the main disadvantage of using magnetic disks for data storage?
a) Lower data transfer rate compared to RAM
b) Susceptibility to physical damage
c) Limited storage capacity
d) High cost
Show Answer
Correct Answer: a) Lower data transfer rate compared to RAM
Explanation: The main disadvantage of using magnetic disks for data storage is the lower data transfer rate compared to RAM. While magnetic disks can store large amounts of data at a lower cost than RAM, the data access rate is slower due to the nature of secondary memory.
Q43. Which of the following is a type of direct access storage device?
a) Magnetic tape
b) Punched card device
c) Hard disk drive
d) Paper tape
Show Answer
Correct Answer: c) Hard disk drive
Explanation: A direct access storage device allows data to be accessed in any order without having to read through intervening records. A hard disk drive is an example of a direct access storage device, as it allows random access to data stored on its magnetic disks.
Q44. What is the main advantage of using optical disks for data storage?
a) High data transfer rate
b) Large storage capacity
c) Durability and resistance to environmental factors
d) None of Above
Show Answer
Correct Answer: c) Durability and resistance to environmental factors
Explanation: The main advantage of using optical disks for data storage is their durability and resistance to environmental factors. Optical disks, such as CDs, DVDs, and Blu-ray discs, use laser technology to read and write data, making them less susceptible to damage from magnetic fields, dust, and temperature fluctuations compared to magnetic storage devices.
Q45. Which of the following is an example of a hierarchical storage management (HSM) system?
a) RAID
b) NAS
c) SAN
d) ILM
Show Answer
Correct Answer: d) ILM
Explanation: Information Lifecycle Management (ILM) is an example of a hierarchical storage management (HSM) system. ILM involves the automated movement of data between different storage devices based on its age, access frequency, and other factors. Q46. This helps optimize storage costs and performance by storing frequently accessed data on high-performance devices and less frequently accessed data on lower-cost devices.
Q46. What is the main purpose of a hierarchical storage system (HSS)?
a) To increase storage capacity
b) To improve data access speed
c) To optimize storage costs based on data access frequency
d) To provide a backup solution for data storage
Show Answer
Correct Answer: c) To optimize storage costs based on data access frequency
Explanation: The main purpose of a hierarchical storage system (HSS) is to optimize storage costs based on data access frequency. HSS automatically moves data between high-cost, high-performance storage devices and low-cost, low-performance storage devices based on how frequently the data is accessed, helping to balance storage costs and performance.
Q47. Which of the following is an example of a mass storage device?
a) RAM
b) SSD
c) Magnetic tape library
d) CPU
Show Answer
Correct Answer: c) Magnetic tape library
Explanation: A mass storage device is used to store large amounts of data, often for backup or archiving purposes. A magnetic tape library is an example of a mass storage device, as it can store enormous amounts of information on magnetic tapes and automatically retrieve them from a large library without human intervention.
Q48. What is the main advantage of near-line storage compared to online storage?
a) Faster data access
b) Lower cost per unit of storage
c) Greater storage capacity
d) Better data security
Show Answer
Correct Answer: b) Lower cost per unit of storage
Explanation: The main advantage of near-line storage compared to online storage is the lower cost per unit of storage. Near-line storage systems store data on devices that are not directly connected to the computer or network, resulting in lower costs compared to online storage systems that require high-performance devices for immediate data access.
Q49. What is the main disadvantage of using RAM for data storage?
a) Lower data transfer rate compared to magnetic disks
b) Susceptibility to physical damage
c) Limited storage capacity
d) Volatility
Show Answer
Correct Answer: d) Volatility
Explanation: The main disadvantage of using RAM for data storage is its volatility. RAM is a type of volatile memory, meaning that it loses its stored data when the power is turned off. This makes it unsuitable for long-term data storage, as data must be constantly refreshed to prevent loss.
Q50. Which of the following is a type of offline storage?
a) Hard disk drive
b) SSD
c) Magnetic tape
d) RAM
Show Answer
Correct Answer: c) Magnetic tape
Explanation: Offline storage is a type of data storage that requires manual intervention to access the data. An example of offline storage is magnetic tape, which must be physically loaded into a tape drive before the data can be accessed.
