Question 1

The reason for the implementation of the cache memory is _________      
A)To increase the internal memory of the system
B)The difference in speeds of operation of the processor and memory
C)To reduce the memory access and cycle time
D)All of the mentioned

Accepted Answer

The primary reason for implementing cache memory is due to the difference in speeds of operation between the processor and the main memory. Cache acts as a high-speed storage area that can be accessed more quickly than the main memory, thereby reducing the time the CPU has to wait for data.

Question 2

The correspondence between the main memory blocks and those in the cache is given by _________        
A)Hash function
B)Mapping function
C)Locale function
D)Assign function

Accepted Answer

Mapping function is used to determine the correspondence between the main memory blocks and those in the cache.

Question 3

The approach where the memory contents are transferred directly to the processor from the memory is called _________  
A)Read-later
B)Read-through
C)Early-start
D)None of the mentioned

Accepted Answer

C

Question 4

The algorithm to remove and place new contents into the cache is called _________    
A)Replacement algorithm
B)Renewal algorithm
C)Updation
D)None of the mentioned

Accepted Answer

The algorithm used for removing and placing new contents into the cache is known as a Replacement algorithm. This is essential for managing the limited space in a cache by deciding which items to replace when the cache is full.

Question 5

Consider a memory organised into 8K rows, and that it takes 4 cycles to complete a read operation. Then the refresh overhead of the chip is _________  
A)0.0021
B)0.0038
C)0.0064
D)0.0128

Accepted Answer

The answer of Consider a memory organised into 8K rows,...
