Question 1: Which of the following is a disadvantage of magnetic and optical storage systems compared to flash drives?
A) Physical motion is required for reading and writing data.
B) They are more susceptible to electronic interference.
C) They offer faster data transfer speeds.
D) They are more compact in size.
Explanation: Flash drives use electronic signals, eliminating the need for moving parts.
Question 2: In flash drives, how are data bits stored?
A) By magnetizing a surface.
B) By burning holes with a laser.
C) By trapping electrons in tiny silicon dioxide chambers
D) By physically moving a read/write head.
Explanation: Flash memory uses this method to store data.
Question 3: Flash memory can retain data for years:
A) Only with constant power supply.
B) Even without external power.
C) Flash memory is non-volatile, meaning it retains data without power.
D) Reformatting is required to maintain data retention.
Explanation: Flash memory is non-volatile, meaning it retains data without power.
Question 4: Why is flash memory not a suitable replacement for main memory (RAM) in computers?
A) It is much faster than RAM.
B) Flash memory is more expensive per GB.
C) Flash memory has a limited write endurance.
D) Flash memory requires a physical connection for access.
Explanation: Repeated erasing can damage flash memory cells, unlike RAM which is designed for frequent writes.
Question 5: Flash memory is ideal for use in:
A) Mainframes due to their large storage capacity.
B) Portable devices like cameras and smartphones due to its compact size and low power consumption.
C) Long-term data archiving due to its superior reliability.
D) Servers that require frequent data writes.
Explanation: Flash memory suits devices where data changes are controlled.
Question 6: Compared to optical discs, flash memory is considered:
A) Less reliable for long-term data storage.
B) More susceptible to physical damage.
C) Slower in data transfer speeds.
D) Less portable due to larger size.
Explanation: Flash memory can degrade over time, while optical discs can last for decades.
Question 7: What is the term for larger flash memory devices designed to replace traditional hard drives?
A) SD Cards
B) USB Drives
C) Solid State Drives (SSDs)
D) MicroSD Cards
Explanation: SSDs offer faster performance and lower power consumption compared to HDDs
Question 8: Solid State Drives (SSDs) offer several advantages, but what is a potential drawback?
A) They are generally smaller than traditional hard drives.
B) They are more resistant to physical shock.
C) SSDs are typically more expensive per gigabyte of storage.
D) They require a separate power source to operate.
Explanation: Flash memory technology is currently costlier than traditional hard drives.
Question 9: Secure Digital (SD) cards are commonly used in:
A) Desktop computers due to their large storage capacity.
B) Portable devices like cameras and car navigation systems due to their compact size.
C) Servers that require high data transfer rates.
D) Data backup solutions due to their durability.
Explanation: SD cards offer convenient storage for these devices.
Question 10: What are the different sizes available for SD cards?
A) Micro only
B) Standard only
C) Standard, Mini, and Micro
D) None of Above
Explanation: SD cards come in different sizes to cater to various devices.
Question 11: What is the maximum storage capacity offered by SDHC cards?
A) Up to 2 GB
B) Up to 32 GB
C) Up to 128 GB
D) They do not have a specific limit.
Explanation: SDHC stands for High Capacity, offering increased storage compared to standard SD cards.
Question 12: What is the potential storage capacity of SDXC cards?
A) Up to 64 GB
B) Up to 128 GB
C) May exceed Terabytes (TB)
D) None
Explanation: explanation
Question 13: Flash drives are also known by which of the following names?
A) Hard Disk Drive (HDD)
B) Pen Drive
C) Optical Drive
D) Memory Card (SD Card)
Explanation: This is a common alternative name for flash drives.
Question 14: Flash memory relies on which type of memory technology?
A) Dynamic Random-Access Memory (DRAM)
B) Static Random-Access Memory (SRAM)
C) Read-Only Memory (ROM)
D) None of the above
Explanation: Flash memory shares similarities with ROM in terms of data retention.
Question 15: When formatting a flash drive, what happens to the existing data?
A) The data is physically erased and unrecoverable.
B) The data remains intact, but access is restricted.
C) The file system table is reorganized, potentially making some data inaccessible without recovery tools.
D) The data is automatically backed up to the cloud.
Explanation: Formatting primarily affects the file system, not the data itself.
Question 16: Which factor most significantly impacts the lifespan of a flash drive?
A) The brand of the flash drive
B) The size of the flash drive
C) The number of write/erase cycles performed
D) The color of the flash drive casing
Explanation: Frequent erasing and writing can shorten the lifespan of flash memory cells.
Question 17: How can you improve the performance and lifespan of a flash drive?
A) Filling the drive to full capacity.
B) Defragmenting the drive regularly.
C) Leaving some free space on the drive and avoiding unnecessary write/erase cycles.
D) option
Explanation: This reduces strain on the memory cells.
Question 18: What security measures can be implemented for data stored on a flash drive?
A) Leaving the drive connected to a computer.
B) Using password protection or encryption software.
C) Sharing the drive with multiple users.
D) Not labeling the drive with your name.
Explanation: Encryption scrambles the data for secure storage.
Question 19: Compared to traditional hard drives, SSDs offer:
A) Slower data transfer speeds.
B) Higher noise levels due to moving parts.
C) Greater resistance to physical shock due to the lack of moving parts.
D) All of the above
