50 Memory Storage MCQs with Detailed Explanations | RAM, ROM, HDD, SSD, USB | CCC, Banking, SSC Exam Preparation
1What is the full form of RAM?
Answer: C
RAM allows data to be read or written in almost the same amount of time regardless of physical location.
2Which memory type is volatile?
Answer: C
Volatile memory requires constant power to maintain stored information.
3What does ROM stand for?
Answer: C
ROM retains its contents even when computer is turned off and typically contains firmware.
4Which storage device has the fastest access speed?
Answer: B
SSDs use flash memory which is much faster than mechanical hard drives.
5What is the smallest unit of computer memory?
Answer: B
8 bits make 1 byte, 4 bits make 1 nibble.
6Which memory is located between CPU and RAM?
Answer: B
Cache stores frequently used data for quick access by CPU.
7What does HDD stand for?
Answer: C
HDDs store data on spinning magnetic platters with read/write heads.
8Which memory type is non-volatile?
Answer: C
Non-volatile memory preserves data without constant power.
9What is the capacity of a standard CD?
Answer: A
CDs use optical storage technology with laser reading.
10Which memory is fastest in computer?
Answer: C
L1 cache is fastest, followed by L2 and L3 cache.
11What does SSD stand for?
Answer: A
SSDs have no moving parts, making them faster and more durable than HDDs.
12Which storage device uses magnetic platters?
Answer: C
HDDs are mechanical devices with moving parts.
13What is virtual memory?
Answer: B
This allows running more applications than physical RAM could normally handle.
14Which memory type is used in USB flash drives?
Answer: C
Flash memory is non-volatile and can be electrically erased and reprogrammed.
15What is the capacity of a standard DVD?
Answer: C
DVDs have higher storage capacity than CDs due to smaller pit size.
16Which memory is directly accessed by CPU?
Answer: C
RAM provides the working space for CPU operations.
17What does BIOS store?
Answer: C
BIOS performs Power-On Self-Test and initializes hardware during boot.
18Which storage device has no moving parts?
Answer: C
SSDs are more durable, faster, and consume less power than HDDs.
19What is the main function of RAM?
Answer: B
More RAM allows more programs to run simultaneously without slowing down.
20Which memory type is used for CPU cache?
Answer: B
SRAM is faster but more expensive than DRAM used in main memory.
