A

ROM

20
Q

What type of memory is used for system boot processes?

A

ROM

21
Q

What does the term ‘memory hierarchy’ refer to?

A

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

22
Q

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

A

True

23
Q

What is the main disadvantage of volatile memory?

A

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

24
Q

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

A

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

25
Q

What is a memory address?

A

A unique identifier for a specific location in memory.

26
Q

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

A

Caching

27
Q

What is the purpose of memory swapping?

A

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

28
Q

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

A

False

29
Q

What is the effect of increasing RAM in a computer?

A

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

30
Q

What does the term ‘latency’ refer to in memory technology?

A

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

31
Q

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

A

Flash memory

32
Q

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

A

To perform hardware initialization during the booting process.

33
Q

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

A

Read operations retrieve data, while write operations store data.

34
Q

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

A

True

35
Q

What is a common use of cache memory?

A

Storing frequently accessed data for quick access by the CPU.

36
Q

What does the term ‘memory bandwidth’ refer to?

A

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

37
Q

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

A

Memory interleaving

38
Q

What is the primary role of the memory controller?

A

To manage data flow to and from the primary memory.

39
Q

What is the significance of memory size in computing?

A

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

40
Q

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

A

True

41
Q

What is the purpose of dual-channel memory architecture?

A

To increase memory bandwidth and improve performance.

42
Q

What is the effect of memory fragmentation?

A

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

43
Q

Fill in the blank: __________ is a technique used to improve memory performance by using multiple memory modules.

A

Memory mirroring

44
Q

What is the function of virtual memory?

A

To extend the apparent amount of RAM by using disk space.

45
Q

True or False: Primary memory is slower than secondary memory.

A

False

46
Q

What is a memory leak?

A

A situation where a program consumes memory without releasing it, leading to reduced available memory.
