Question

**Which among the following statements is incorrect?**

1. Cache memory keeps the programs that can be run in a short amount of time.
2. Cache memory stores data in permanent use.
3. Cache memory is faster than main memory.
4. The size of cache is usually small.

Accepted Answer

**Solution:**

1. Cache memory is a small, fast memory that stores frequently accessed data and instructions to speed up processing.

2. It is a type of volatile memory, which means it loses its contents when power is off. Hence, it does **not** store data permanently.

3. Cache memory is indeed faster than main memory (RAM).

4. The size of cache memory is usually small compared to main memory.

Therefore, the incorrect statement is:

- "Cache memory stores data in permanent use."

**Answer:** (2) Cache memory stores data in permanent use.
