Lec 5,6,8

Which of the following is NOT an internal memory type?

• Main memory

• Registers

• Cache

• Disk storage

What is the common word length for internal memory?

• 4, 8, 12, or 16 bits

• 8, 16, 32, or 64 bits

• 16, 32, 48, or 64 bits

• 32, 64, 128, or 256 bits

In which access method is access time independent of location or previous access?

• Sequential

• Direct

• Random

• Block-based

Which access method is used by cache memory?

• Sequential

• Direct

• Random

• Associative

What is the formula for transfer rate?

• Tr = cycle time

• Tr = 1/cycle time

• Tr = access time × cycle time

• Tr = access time + cycle time

In the memory hierarchy, what happens as we go down?

• Increasing cost, decreasing capacity

• Decreasing cost, increasing capacity, increasing access time

• Increasing cost, increasing access time

• Decreasing capacity, decreasing access time

What is the primary purpose of cache memory?

• To replace main memory completely

• To improve performance by providing fast access to frequently used data

• To increase total memory capacity

• To reduce the cost of memory systems

What happens when a cache hit occurs?

• Data is fetched from main memory

• Data is retrieved directly from cache

• The entire block is replaced

• The processor waits for the next cycle

When a cache miss occurs, what is loaded into the cache?

• Only the required word

• The entire block containing the required word

• The next sequential word

• All related data

What principle explains why loading entire blocks into cache is effective?

• Temporal locality

• Locality principle

• Spatial distribution

• Random access principle
