Solution

Answer:

(D) level 3 cache is a large block of memory on the motherboard for performance purposes.

Level 3 cache is one level of cache memory which is located on mother board in old computers. It is most popular used cache memory in old days now a days mostly level 1 cache is used.

Level 3 cache has slower speed compared to level 1 and level 2 and it is biggest in size. The cost level 3 cache is lower because of missing hit ratio is low comparing to level 2. Typically the size of this cache is 8 MB.

Example: Intel Core i7

By taking intel core i7, we have level 3 cache memory of 8MB size and maybe looking for data for 30-40 cycles. It search speed is slower compared to level 2 cache memory.
