Q51. What is the main advantage of using solid-state drives (SSDs) for data storage?
a) High data transfer rate
b) Large storage capacity
c) Durability and resistance to environmental factors
d) Low cost
Show Answer
Correct Answer: a) High data transfer rate
Explanation: The main advantage of using solid-state drives (SSDs) for data storage is their high data transfer rate. SSDs use flash memory to store data, which allows for quicker data retrieval and write times compared to the spinning magnetic disks used in hard disk drives (HDDs).
Q52. What is the main disadvantage of using optical disks for data storage?
a) Lower data transfer rate compared to magnetic disks
b) Susceptibility to physical damage
c) Limited storage capacity
d) High cost
Show Answer
Correct Answer: a) Lower data transfer rate compared to magnetic disks
Explanation: The main disadvantage of using optical disks for data storage is the lower data transfer rate compared to magnetic disks. Optical disks use laser technology to read and write data, which is generally slower than the magnetic technology used in magnetic disks.
Q53. Which of the following is a type of 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.
Q54. What is the main advantage of using RAM for data storage?
a) High data transfer rate
b) Large storage capacity
c) Durability and resistance to environmental factors
d) Low cost
Show Answer
Correct Answer: a) High data transfer rate
Explanation: The main advantage of using RAM for data storage is its high data transfer rate. RAM is a type of volatile memory that stores data temporarily for quick access by the computer’s processor. This allows for faster data retrieval and processing compared to other storage devices, such as magnetic disks and optical disks.
