Consider the following :
- 1Small memory
- 2Less expensive memory
- 3Fast memory
Which of the above are the characteristics of the cache memory?
general-scienceinformation-technology
- A1 and 2 only
- B2 and 3 only
- C1 and 3 only
- D1, 2 and 3
Explanation
Cache memory is a small, very fast SRAM placed close to the CPU to speed up access to frequently used data. It is expensive per bit, not less expensive, so 'less expensive memory' is not its characteristic. Hence its characteristics are 1 (small) and 3 (fast) only.
