Q1. Which of the following is a type of sequential access memory?
a) RAM
b) Magnetic tape
c) SSD
d) HDD
Show Answer
Correct Answer: b) Magnetic tape
Explanation: Sequential access memory (SAM) is a class of data storage devices that read stored data in a sequence, as opposed to random access memory (RAM) where data can be accessed in any order. Magnetic tape is a common example of a sequential access memory device.
Q2. What is a direct-access storage device (DASD)?
a) A storage device that reads data sequentially
b) A storage device that allows random access to data
c) A storage device that only stores data temporarily
d) A storage device that requires manual intervention for data retrieval
Show Answer
Correct Answer: b) A storage device that allows random access to data
Explanation: A direct-access storage device (DASD) is a secondary storage device that allows random access to data, meaning each physical record has a discrete location and a unique address. Examples of DASD include hard disk drives, optical disc drives, and flash memory units.
Q3. What is the primary function of a tape drive?
a) To read and write data on magnetic tapes
b) To control the movement of the tape
c) To store data in a non-volatile manner
d) To provide random access to data
Show Answer
Correct Answer: a) To read and write data on magnetic tapes
Explanation: A tape drive is a data storage device that reads and writes data on magnetic tapes. It is used primarily for backup and archiving purposes due to its high storage capacity and low cost per unit of storage.
Q4. Which of the following is a type of magnetic tape?
a) Linear Tape-Open (LTO)
b) Compact Disc (CD)
c) Solid State Drive (SSD)
d) Hard Disk Drive (HDD)
Show Answer
Correct Answer: a) Linear Tape-Open (LTO)
Explanation: Linear Tape-Open (LTO) is a type of magnetic tape used for data storage and backup. It is a high-capacity, high-performance tape format that offers features such as data compression, encryption, and partitioning.
Q5. Which of the following is a disadvantage of magnetic tape storage?
a) High data density
b) Resistance to wear
c) Non-volatility
d) Prone to disintegration
Show Answer
Correct Answer: d) Prone to disintegration
Explanation: Magnetic tape is a medium for magnetic storage made of a thin, magnetizable coating on a long, narrow strip of plastic film. While it has advantages such as high data density, resistance to wear, and non-volatility, it is prone to disintegration and can suffer from sticky-shed syndrome, a deterioration that may render the tape unusable.
Q6. What is the primary function of a tape controller?
a) To read and write data on magnetic tapes
b) To control the movement of the tape
c) To store data in a non-volatile manner
d) To provide random access to data
Show Answer
Correct Answer: b) To control the movement of the tape
Explanation: A tape controller is a device that controls the movement of the magnetic tape within a tape drive. It manages the read and write operations, as well as the positioning of the tape for data access.
Q7. What is the primary difference between sequential access and direct access storage devices?
a) The speed at which data can be accessed
b) The order in which data is accessed
c) The type of data that can be stored
d) The amount of data that can be stored
Show Answer
Correct Answer: b) The order in which data is accessed
Explanation: The primary difference between sequential access and direct access storage devices is the order in which data is accessed. Sequential access devices read stored data in a sequence, while direct access devices allow data to be accessed in any order without having to read through intervening records.
Q8. Which of the following is an example of a magnetic disk?
a) Floppy disk
b) Magnetic tape
c) Optical disk
d) RAM
Show Answer
Correct Answer: a) Floppy disk
Explanation: A magnetic disk is a storage device that uses a magnetization process to write, rewrite, and access data. It is covered with a magnetic coating and stores data in the form of tracks, spots, and sectors. Examples of magnetic disks include hard disks, zip disks, and floppy disks.
Q9. What is the main advantage of direct access storage devices over sequential access storage devices?
a) Larger storage capacity
b) Faster data retrieval
c) Lower cost
d) Longer lifespan
Show Answer
Correct Answer: b) Faster data retrieval
Explanation: The main advantage of direct access storage devices over sequential access storage devices is faster data retrieval. Direct access storage devices allow the host system to access data directly from wherever it is stored within the storage device, enabling efficient data processing and analytics.
Q10. Which of the following is a principle of operation for magnetic disks?
a) Sequential access
b) Direct access
c) Random access
d) Parallel access
Show Answer
Correct Answer: c) Random access
Explanation: Magnetic disks use random access, meaning that data can be read or written at any location on the disk without having to move sequentially through the data. This makes them suitable for real-time data processing and faster access times compared to sequential access storage devices like magnetic tapes.
