Question 11

Fill in the blank: __________ is a type of RAM that can be accessed faster than traditional RAM.

Answer 11

SRAM (Static Random Access Memory)

Question 12

What is DRAM?

Answer 12

Dynamic Random Access Memory, which needs to be refreshed thousands of times per second.

Question 13

True or False: Cache memory is a type of primary memory.

Answer 13

Answer 16

Primary memory provides faster data access speeds compared to secondary memory.

Question 17

True or False: Primary memory is typically larger than secondary memory.

Answer 17

False

Question 18

What is the typical size range for RAM in modern computers?

Answer 18

From 4 GB to 64 GB or more.

Question 19

Fill in the blank: __________ memory is used to store firmware and system-level software.

Answer 19

ROM

Question 20

What type of memory is used for system boot processes?

Answer 20

ROM

Question 21

What does the term ‘memory hierarchy’ refer to?

Answer 21

The structured arrangement of different types of memory in a computer system, from fastest to slowest.

Question 22

True or False: All types of primary memory are accessible by the CPU.

Answer 22

True

Question 23

What is the main disadvantage of volatile memory?

Answer 23

It loses all stored data when the power is turned off.

Question 24

What is the role of memory management in a computer system?

Answer 24

To efficiently allocate and manage primary memory resources among various applications.

Question 25

What is a memory address?

Answer 25

A unique identifier for a specific location in memory.

Question 26

Fill in the blank: __________ is a process that allows the CPU to quickly access frequently used data.

Answer 26

Caching

Question 27

What is the purpose of memory swapping?

Answer 27

To move data from RAM to disk storage when RAM is full, allowing for more applications to run.

Question 28

True or False: The CPU can access both primary and secondary memory at the same speed.

Answer 28

False

Question 29

What is the effect of increasing RAM in a computer?

Answer 29

It can improve performance by allowing more applications to run simultaneously.

Question 30

What does the term 'latency' refer to in memory technology?

Answer 30

The delay between a request for data and the delivery of that data.

Question 31

Fill in the blank: __________ is a type of non-volatile memory used in embedded systems.

Answer 31

Flash memory

Question 32

What is the main purpose of the BIOS stored in ROM?

Answer 32

To perform hardware initialization during the booting process.

Question 33

What is the difference between read and write operations in memory?

Answer 33

Read operations retrieve data, while write operations store data.

Question 34

True or False: Primary memory can be directly accessed by the CPU.

Answer 34

True

Question 35

What is a common use of cache memory?

Answer 35

Storing frequently accessed data for quick access by the CPU.

Question 36

What does the term 'memory bandwidth' refer to?

Answer 36

The amount of data that can be read from or written to memory in a given time period.

Question 37

Fill in the blank: __________ is a method of organizing memory to improve access speed.

Answer 37

Memory interleaving

Question 38

What is the primary role of the memory controller?

Answer 38

To manage data flow to and from the primary memory.

Question 39

What is the significance of memory size in computing?

Answer 39

Larger memory sizes allow for more data to be processed simultaneously.

Question 40

True or False: Cache memory is located on the motherboard.

Answer 40

True

Question 41

What is the purpose of dual-channel memory architecture?

Answer 41

To increase memory bandwidth and improve performance.

Question 42

What is the effect of memory fragmentation?

Answer 42

It can lead to inefficient use of memory and reduced performance.
