#1
Which of the following is a volatile memory type?
RAM
ExplanationVolatile memory loses its contents when the power is turned off.
#2
What does CPU stand for?
Central Processing Unit
ExplanationCPU is the primary component of a computer responsible for executing instructions.
#3
Which type of memory is commonly used for storing BIOS firmware?
ROM
ExplanationRead-Only Memory (ROM) is commonly used for storing BIOS firmware as it retains data even without power.
#4
Which of the following is a type of non-volatile memory?
ROM
ExplanationNon-volatile memory retains its contents even when the power is turned off.
#5
What is the purpose of a cache memory?
To store frequently accessed data for quicker access
ExplanationCache memory reduces data access time by storing frequently used data closer to the CPU.
#6
What is the role of virtual memory in computer systems?
To extend the capacity of physical RAM
ExplanationVirtual memory uses disk space to simulate additional RAM when physical memory is full.
#7
What is the purpose of a memory controller?
To manage data transmission between CPU and memory
ExplanationMemory controller regulates the flow of data between the CPU and memory modules.
#8
What is the typical size of a cache memory in modern CPUs?
Several megabytes
ExplanationCache memory in modern CPUs typically ranges in size from a few megabytes to tens of megabytes.
#9
Which memory hierarchy level has the fastest access time?
Primary Memory
ExplanationPrimary memory, such as RAM, offers the fastest access time compared to secondary storage.
#10
Which of the following is a characteristic of DDR4 memory?
Higher data transfer rates than DDR3
ExplanationDDR4 memory offers faster data transfer rates compared to its predecessor DDR3.
#11
What is the purpose of memory swapping?
To transfer data between RAM and secondary storage
ExplanationMemory swapping moves data between RAM and secondary storage to free up RAM space.
#12
What does the term 'latency' refer to in computer memory?
The time delay between initiating a request and receiving a response
ExplanationLatency in memory refers to the time delay between requesting data and receiving it.
#13
Which memory technology provides the fastest access time?
SRAM
ExplanationStatic Random Access Memory (SRAM) provides the fastest access time among memory technologies.
