Understanding Memory Hierarchy Concepts

What is the primary purpose of cache memory in a computer system?

• To store permanent data

• To speed up data access for the CPU

• To increase the storage capacity

• To manage power consumption

Which of the following is typically the fastest type of cache memory?

• L3 Cache

• L2 Cache

• L1 Cache

• Main Memory

What is memory access time?

• The time taken to write data to a storage device

• The time taken to read or write data to memory

• The time taken to boot up a computer

• The time taken to transfer data over a network

What unit is commonly used to measure data transfer rates?

• Bytes per second (Bps)

• Bits per second (bps)

• Kilograms per second (kg/s)

• Metres per second (m/s)

What is the typical role of L2 cache in a computer system?

• To store the operating system

• To act as a buffer between the CPU and RAM

• To store user files

• To manage network connections

Which of the following factors does NOT affect memory access time?

• Memory type

• CPU speed

• Network bandwidth

• Cache size

Which of the following is NOT a type of cache memory?

• L1 Cache

• L2 Cache

• L3 Cache

• Virtual Cache

What is the typical unit of measurement for memory access time?

• Seconds

• Milliseconds

• Microseconds

• Nanoseconds

What is the relationship between cache size and performance?

• Larger cache size always decreases performance

• Larger cache size always increases performance

• Larger cache size can increase performance up to a certain point

• Cache size does not affect performance

Which of the following best describes the function of cache memory?

• To store large amounts of data permanently

• To provide temporary storage for frequently accessed data

• To manage network traffic

• To increase the physical storage capacity of a computer
