Test by Bikram | Computer Organization and Architecture | Test 2 | Question: 16

Question

Consider the following statements about the Locality of Reference principle used in the computer memory systems.

1. The principal states that an already accessed memory location is accessed further again and it is also more likely that adjacent memory locations will also be accessed.
2. The principle states that memory can be accessed simultaneously and in parallel on the basis of data content rather than by specific address or location.
3. This principle help to reduce the average access time, and increase cache memory hits.

Which of the above statements is/are TRUE?

• A. I only
• B. II only
• C. II and III only
• D. I and III only

Answer 1

(A) should be correct option for this question!

Statement III is not true because Locality of Reference principle doesn't increase memory hit. It increases cache hit by bringing more words into a cache block, though it reduces average access time.

by "memory hit" --  guess it means "cache memory hit" .

so in that case statement III is correct and  option D is correct too.
